Database design – Basic for web development

noreply@blogger.com (Anonymous) — Sat, 03 May 2014 11:49:00 +0000

For all database designs, there are a set of standard rules and best practices to follow, all of which can help a database stay organized and help to team up with the respective site in a smart and efficient way.

What Functionality is Needed from the Database?

The first method for planning for a database is to simply brainstorm, on paper or otherwise, concerning what the database will need to store, and what the site will need out of it. Try not to think of the individual fields or tables that will be needed at this point - all that specific planning can take place later. The goal is to start with a general and complete view, and narrow down. It can often times be more difficult to add in items later, rather than get it right the first time.

Think outside the database. Try to think about what the website will need to do. For example, if a membership website is needed, the first instinct may be to begin thinking of all the data each user will need to store. Forget it, that's for later. Rather, write down that users and their information will need to be stored in the database, and what else? What will those members need to do on the site? Will they make posts, upload files or photos, or send messages? Then the database will need a place for files/photos, posts, and messages.

What information will they need to derive from the site? Will they need to search for their favorite recipe, be able to access member-only content, or need to look up products and their recently purchased or viewed products? Then the database will need a place to hold those recipes, a place for content that is defined as members-only or not, or hold all products and create a method to link certain products to a specific member.

Determining Tables and Fields

The next phase would be to begin determining exactly what tables and fields one would need in the database. This is the core of database design, and the most difficult part. Using correct methods for linking tables together, sorting the data within each table correctly, and grouping it or keeping it separate are all arising problems when it comes to database design. At this point, list out what tables and fields are clear at this point, trying to be as specific as possible. Through the process, items can be rearranged or reorganized to improve the database's efficiency and security.

USE A DATA MODELING TOOL

Now that you know what the site will need to do, it's time to organize what exact information needs to be stored. A great database design tool can be helpful for this; specifically one that can help set up visual database models, suchas MySQL Workbench (for MySQL databases only) or DBDesigner4.Gliffy is also a great free online application for creating flowcharts and database models.

Become familiar with the common icons and standard visual elements necessary to create database models, and begin planning via flowcharts and diagrams ahead of time. This can sort out logical errors before any actual databases are created.

RELATIONAL DATABASES

Almost all databases are relational databases. This means that the tables in the database are related to each other in some way. For example, if a there is a member on an ecommerce website, that member may be related to certain products based on what they ordered last, or what they have expressed they are interested in. For a blog database, authors would have to be somehow related to the posts they wrote, and logged in users could be related to any comments they've left.

By using the techniques for relationaldatabases, we can store plenty of information in an organized fashion within separate tables: one table for members, one for posts, another for comments, and yet another for products. Then, we can link the data between different tables together via unique keys.

Every entry in every table needs a uniqueprimary key. This is the "social security number" or "bar code" for each entry. It is unique to each entry, and no other entry can have the same ID in the same table. Having unique usernames or product names in a database table is not enough. It is far more efficient, and best practice as well, to use unique primary keys. Even with other types of unique fields, a database is still vulnerable to duplicate records, which can later break code within the website.

To relate two tables we use a foreign key, which is just a number ID that references a unique key in another table, usually our primary key.

GROUPING OR SEPARATING DATA INFO FIELDS

Within fields, it's also important to know when to group certain pieces of data together, and when to keep them separate. A good way to determine which information should be in the same field or otherwise is to think about what it would take to change that piece of information if necessary. For example, would it be necessary to place a full address in separate fields, based on 1) street address, 2) city, 3) state, 4) zip code, and then 5) country?

Is it essential for the functionality of the site (perhaps users or admins would need to search addresses by state only), or is it just a waste of fields and database space? If it's not essential, just to change an address the database would have to update five separate fields, when it could just update one field in string form. In order to keep such a field organized, one could take in the information via an HTML form with these fields separated, but then concatenate them into one single string before placing the address into the database.

This is just one example, but always keep in mind the most efficient ways to organize table fields, and when to combine them, or when to keep them separate for the sake of the website's functionality.

DATABASE NORMALIZATION

Database normalization is a set of guidelines created by the community for organizing data in a database efficiently. We've mentioned a few of the most important and basic practices already, which are included in some of the most standard normalization forms. There are five normal forms to follow, and it's a good idea to learn about these five forms in order to conform any database's design to their best practices.

Database normalization is a large topic, but just understanding the basics can help tremendously. To take a look at each normalization form and a general overview of the concept, be sure to take a look at Database Normalizaiton Basics.

Conclusion

Database design can be a heavy subject with a lot to cover, but it doesn't take a lot to learn the basics and get a good design for the most basic of database structures. Perhaps the most important rule and phase to designing a database is the initial design and brainstorming phase. This is what allows any developer to get all of the information they need up front, and to begin organizing as necessary. Only with all of the necessary information to work with can a great database design be created intelligently, with tables linked properly, and best practices intact.

The goal of any database is to be efficient and scalable. Data is always being edited, added, and deleted, so it's important to keep a database organized in order to maintain this constant changing set of data. Be sure to design a database that deletes only the information necessary when needed, adds no duplicate records, and is able to reference other data throughout the database easily and simply.

Beyond 2012: The Future of Database Administrator Careers

noreply@blogger.com (Anonymous) — Sat, 12 Apr 2014 10:57:00 +0000

Let's tie together the last several columns on "2012 Might Really be The End of the World." In this series, When discussed several megatrends in the general IT industry that will have a tremendous impact on the database administration (DBA) profession. The megatrends include both software-related (virtualization and cheap cloud database services) and hardware-related (SSDs and massively multi-core CPUs). These technologies have the potential to obviate many of the core competencies of the DBA, with the first two eliminating or lessening the need for server and hardware configuration and provisioning, and the last two diminishing the need for IO tuning and query tuning, respectively. But those are trends that will take years to reach fruition. What about the near future?

In actuality, prospects for current and future DBAs. Here are a few reasons.

First, most companies, even many Fortune 500-sized organizations, aren't getting basic database administration right in the first place. They can't institutionalize the benefits of basic information management techniques until they've had a few years of solid experience with their data. These organizations, both great and small, need some time to understand their database before they can exploit their data assets or effectively extract business intelligence from them. I'm doubtful that immature organizations can leapfrog into the newest technologies without wasting a lot of money, time, and morale.

Second, there aren't enough DBAs, and there won't be for the foreseeable future. The Bureau of Labor Statistics shows there are currently 380,000 people working under the title of "databaseadministrator." (The most recent data I could find was from 2009.) Of course, many more do the work of a DBA without that title. However, database administration and its variants are considered high-growth. There's only about a 4 % unemployment rate for DBAs, and demand far outstrips supply.

Third, our higher education system just doesn't get it. It's not turning out the kind of graduates needed to step immediately into database management professions. Even the most savvy and progressive of universities don't think deeply about data. They're still focused primarily on algorithms (for the Computer Science department) or requirements and business analysis (for Information Systems majors). And those who do think about data usually offer, at best, two courses on database management.

So, a new graduate must spend at least a few years in the trenches before he or she can become an effective part of a data management team. This effectively winnows out many potential candidates. It's also given rise to the term "accidental DBA," which we see daily in the SQL Server world on blogs and conference presentations. The accidental DBA is someone who was given DBA responsibilities with no formal training on the subject. He or she might be the best SQL developer on the dev team. Or they might be the most analytical of the business analysts. Sometimes, they just happen to be the person standing closest to the server rack when the boss says, "We need a volunteer to be a DBA - ah, you!"

With so many accidental DBAs put in charge of valuable data assets, organizations essentially start the cycle all over again, which goes back to my first point - companies aren't getting even the basics of database administration right.

So, yes - if you're a DBA today, you have some things to learn and some things to worry about in the future. But you have plenty of time to learn them. Once you learn new technologies like virtualization and IO tuning with SSDs, you'll be able to leverage those skills into promotions and pay raises. Because as long as we have "accidental DBAs" coming up from the trenches, large organizations will have to pay a premium for the elite data management professionals who know both the best practices for operational database administration - and how to take advantage of the newest technologies.

Introduction to Oracle Concepts

noreply@blogger.com (Anonymous) — Sat, 29 Mar 2014 11:38:00 +0000

This is a brief introduction to Oracle Concepts for the DBA. Conceptually, you can think of an Oracle database as nothing more than a large electronic filing cabinet, a place to store and retrieve information. At the computer level, Oracle is a computer program that manages an electronic filing cabinet.

What is an Oracle Database?

A database is a collection of data. An Oracle database holds its data in a coordinated set of files stored on disk, including following types:

Parameter Files - The Oracle Parameter File (PFILE or SPFILE) holds initialization parameters which indicate where the control files are, how memory is allocated, how logging is performed, and other characteristics of the Oracle instance.
Control Files - The Control File stores information needed to verify that the database is consistent, including a list of all database files making up the instance and other important data.
Redo Log Files - The Redo Log files store a sequence of entries describing all actions taken against the database. This data is used to recover a database in the event of instance failure.
Data Files - The Data Files contain blocks of data which store database objects (e.g., tables, indexes, materialized views, etc.) in the database.
Temp Files - The Temp files contains data used temporarily including intermediate results, sort results and so forth.

Duties of Database Administrators

The principal responsibility of a database administrator (DBA) is to make enterprise data available to its users. DBAs must work closely with the developers to ensure that their applications make efficient use of the database, and with system administrators to ensure that physical resources are adequate and used efficiently.

Oracle DBAs are responsible for understanding the Oracle Database architecture and how the database works. DBAs can expect to perform the following tasks:

Installing, upgrading, and patching Oracle Database software
Designing databases, including identifying requirements, creating the logical design (conceptual model), and physical database design
Creating Oracle databases
Developing and testing a backup and recovery strategy, backing up Oracle databases regularly, and recovering them in case of failures
Configuring the network environment to enable clients to connect to databases
Starting up and shutting down the database
Managing storage for the database
Managing users and security
Managing database objects such as tables, indexes, and views
Monitoring and tuning database performance
Investigating, gathering diagnostic data for, and reporting to Oracle Support Services any critical database errors
Evaluating and testing new database features

The types of users and their roles and responsibilities depend on the database environment. A small database may have one DBA. A very large database may divide the DBA duties among several specialists, for example, security officers, backup operators, and application administrators.

Tools for Database Administrators

Oracle provides several tools for use in administering a database. This section describes some commonly used tools:

Oracle Enterprise Manager
SQL*Plus
Tools for Database Installation and Configuration
Tools for Oracle Net Configuration and Administration
Tools for Data Movement and Analysis

Advantages & Disadvantages of Oracle SQL

noreply@blogger.com (Anonymous) — Sat, 08 Mar 2014 10:41:00 +0000

Oracle SQL Developer is a free integrated development environment that simplifies the development and management of Oracle Database. SQL Developer offers complete end-to-end development of your PL/SQL applications, a worksheet for running queries and scripts, a DBA console for managing the database, a reports interface, a complete data modeling solution, and a migration platform for moving your 3rd party databases to Oracle.

Oracle SQL (structured query language) is a computer language that is designed to manage data stored in RDBMS (relational database management systems) databases. An RDBMS is a system of tables that store data and represents the relationships between them. SQL has various structural elements, including clauses, expressions, queries, statements and predicates. Oracle SQL is commonly used for the management of data stored in Oracle databases (also called Oracle RDBMS or simply Oracle).

Oracle SQL Developer is a free graphical tool for database development. With SQL Developer, you can browse database objects, run SQL statements and SQL scripts, and edit and debug PL/SQL statements. You can also run any number of provided reports, as well as create and save your own. SQL Developer enhances productivity and simplifies your database development tasks.

Advantage: Centralized Management System and Control

Oracle SQL statements allow data to be controlled from a central tabular repository. A database administrator (DBA) is responsible to create users, assign privileges, add records, delete redundant information, modify existing data and process queries. This centrally stored data is shared and accessed by various applications. This eliminates data entry and data storage redundancy.

Advantage: Standardization

A major advantage of Oracle SQL is its standardization and consistency among various different implementations. SQL was first standardized by ANSI (American Standards Institute) in 1986, and further ratified in 1987 by the International Organization for Standardization (ISO), which remains its standardization body.

Disadvantage: Inability to Implement Recursive Processing

According to "SQL for Dummies," one of the major drawbacks of SQL is its incapability to execute recursive processing. Recursive processing is a type of computer function (or program) in which one of the steps of a program (or procedure) reruns the entire program (or procedure). SQL lacks looping constructs that are common in other high-level programming languages, such as for and what loops. It cannot repeat actions and there is no way to define repetitive looping constructs in SQL.

Disadvantage: Incompatibility and Complexity
One of the major disadvantages of Oracle SQL is inconsistency and data incompatibility in the areas of time and date syntax, string concatenation and case sensitivity. The language is complex, with a keyword approach similar in structure to COBOL (common business-oriented language), with fewer syntax and grammar rules.

Disadvantage: Limited Functionality
SQL is a domain specific or special-purpose language, and its use is limited to a specific program domain. SQL statements are operated on tables and sets of data, such as personnel databases and accounting spreadsheets. SQL is a declarative domain specific language that is limited to the tabular representation of data.

Types of DBMS

noreply@blogger.com (Anonymous) — Sat, 15 Feb 2014 12:17:00 +0000

Database Management Systems

All of us know that, a Database is a collection of records. Database management systems are designed for managing all the records. Database Management is a software system that uses a standard method and running queries with some of them designed for the oversight and proper control of databases.

Types of Database Management Systems:

There are four structural types of database management systems:

Hierarchical databases.
Network databases.
Relational databases.
Object-oriented databases

Hierarchical Databases :

It is very fast and simple. In a hierarchical database, records contain information about there groups of parent/child relationships, just like as a tree structure. The structure implies that a record can have also a repeating information. In this structure Data follows a series of records, It is a set of field values attached to it. It collects all records together as a record type. These record types are the equivalent of tables in the relational model, and with the individual records being the equivalent of rows. To create links between these record types, the hierarchical model uses these type Relationships.

Network Database :

A network databases are mainly used on a large digital computers. It more connections can be made between different types of data, network databases are considered more efficiency It contains limitations must be considered when we have to use this kind of database. It is Similar to the hierarchical databases, network databases .Network databases are similar to hierarchical databases by also having a hierarchical structure. A network database looks more like a cobweb or interconnected network of records.

In network databases, children are called members and parents are called occupier. The difference between each child or member can have more than one parent.

Object-Oriented Model :

In this Model we have to discuss the functionality of the object oriented Programming .It takes more than storage of programming language objects. Object DBMS's increase the semantics of the C++ and Java .It provides full-featured database programming capability, while containing native language compatibility. It adds the database functionality to object programming languages.This approach is the analogical of the application and database development into a constant data model and language environment. Applications require less code, use more natural data modeling, and code bases are easier to maintain. Object developers can write complete database applications with a decent amount of additional effort.

The object-oriented database derivation is the integrity of object-oriented programming language systems and consistent systems. The power of the object-oriented databases comes from the cyclical treatment of both consistent data, as found in databases, and transient data, as found in executing programs.

Relational Databases :

In relational databases, the relationship between data files is relational. Hierarchical and network databases require the user to pass a hierarchy in order to access needed data. These databases connect to the data in different files by using common data numbers or a key field. Data in relational databases is stored in different access control tables, each having a key field that mainly identifies each row. In the relational databases are more reliable than either the hierarchical or network database structures. In relational databases, tables or files filled up with data are called relations (tuples) designates a row or record, and columns are referred to as attributes or fields.

Relational databases work on each table has a key field that uniquely indicates each row, and that these key fields can be used to connect one table of data to another.

Database Design

noreply@blogger.com (Anonymous) — Sat, 01 Feb 2014 12:07:00 +0000

Introduction

Database Design is the step by step process of producing a detailed Data Model of a Database. This Logical Data Model contains all the needed Logical and Physical Design choices and physical storage parameters needed to generate a design in a Data Definition Language, which can then be used to create a Database. A fully attributed Data Model contains detailed attributes for each entity.

The term Database Design can be used to describe many different parts of the design of an overall Database System. Principally, and most correctly, it can be thought of as the Logical Design of the base Data Structures used to store the data. In the Relational Model these are the Tables and Views. In an Object Database the entities and relationships map directly to object classes and named relationships. However, the term Database Design could also be used to apply to the overall process of designing, not just the base Data Structures, but also the forms and queries used as part of the overall Database application within the Database Management System (DBMS).

The process of doing Database Design generally consists of a number of steps which will be carried out by the database designer. Usually, the designer must:

Determine the relationships between the different data elements.
To add as a distinct feature, element, or quality a logical structure upon the data on the basis of these relationships.

DATABASE DESIGN BASICS :

A properly designed database provides you with access to up-to-date, accurate information. Because a correct design is essential to achieving your goals in working with a database, investing the time required to learn the principles of good design makes sense. In the end, you are much more likely to end up with a database that meets your needs and can easily accommodate change.

This article provides guidelines for planning a database. You will learn how to decide what information you need, how to divide that information into the appropriate tables and columns, and how those tables relate to each other. You should read this article before you create your first database.

Design process :

Determine the purpose of the database.
Find and organize the information required.
Divide the information into tables.
Turn information items into columns.
Specify primary keys.
Set up the table relationships.
Refine the design
Apply the normalization rules.

Oracle :

Oracle is the world's most complex and having acquired worldly knowledge or refinement databases. Learning Oracle is only appropriate for experienced computer scientists and information systems professionals with years of required prior condition training will be able to successfully get a career as an Oracle professional.

Most Oracle Applications databases support mission critical systems, a successful Oracle Applications

DBA must have these skills:

Outstanding Communications Skills -

Oracle Applications DBA's must interface with the end-user community and they must have college-level communications skills, being able to communicate clearly, both orally and with written communications.
Business Degree -

Most successful Oracle Applications DBA staff have advanced degrees in business administration, almost all from AACSB accredited collegiate business schools. Graduates of sub-optimal business schools will have very difficult time obtaining a job in Oracle Applications administration, and a firm understanding of business processes is essential to perform many of the duties of the Oracle Applications DBA job role.
DBA skills -

Most Oracle Applications DBA staff have at least five years of full-time progressive DBA experience, and they sometimes have Oracle certifications such as OCP Oracle Certified Professional and OCM Oracle Certified Master. The Oracle Applications DBA must also have a good understanding of related technologies, especially Java (JDeveloper, J2EE, Apache) and Oracle Application Server.

What College Degrees are best for the DBA?

Companies are now requiring a combination of technical and managerial skills and the best-fits are those with an undergraduate degree in Computer Science and a MBA in Information Systems. Employers need a DBA who can understand business systems areas (accounting, finance, marketing) and MBA's are a perfect fir for the DBA job role.

Note :

Remember, there is a difference between working in database administration and being "the" DBA, the person solely responsible for the corporations data resources.

DBA (Database Administrator)

As all we know that DBA is a person related to the Database field. The person who knows SQL programming language, works in IT industry as a SQL Programmer.After that the very first Question comes in our mind is what is the difference between DBA and SQL Programmer?
A Database Programmer requires more advanced skills in SQL programming than a DBA may have, and Database Programmers may not have and do not require the skills of database administration, backing up, restoring, monitoring or tuning to do their job well. It means that, the Database Programmer does not require the knowledge about how to tackel the Database but it must for the Database Administrator to have the detailed knowledge about the administration or we can say that how to tackel the Database.
