A9.2-R5-Web Application Development Using PHP

2020-08-09T17:55:00.005+05:30

A9.2-R5-Web Application Development Using PHP

Introduction

The combination of PHP and MySQL is the most convenient approach to dynamic, database-driven web design. Flexible, scalable, extensible, stable, open—PHP is all of these and more, which is why it’s one of the most popular programming toolkits in the world. Today, more than 20 million domains use PHP, including Facebook and Yahoo. PHP is easily embedded with HTML, and is used to manage dynamic content and the databases of websites or, we can say, Web applications. We can use PHP with many popular databases like MySQL, PostgreSQL, Oracle, Sybase, Informix and Microsoft SQL Server.

So, using PHP is also good economics for organizations: it allows them to save on licensing fees and expensive server hardware, while simultaneously producing higher- quality products in shorter time frames. Any would-be developer on a Unix/Linux or even a Windows/Apache platform will need to master these technologies. At the same time, JavaScript is important, as it provides in-browser dynamic functionality and, through Ajax, hidden communication with the web server to create seamless interfaces. In conjunction with CSS, these technologies integrate to provide a formidable array of powerful web-development tools. 2.11.2. Objective

A5-R5- Data Structure Through Object Oriented Programming Language

2020-08-08T21:33:00.007+05:30

A5-R5- Data Structure Through Object Oriented Programming Language

Introduction

Good knowledge of data structures and algorithms is the foundation of writing good code. Having good knowledge of essential Data structures like array, string, linked list, stack, queue, tree, graph etc makes one understand when to use which Data Structure and accordingly reduce the space and time complexity of the algorithm. Using the right data structure can drastically improve the performance of an algorithm. In depth understanding of Data Structures, enables one to understand how computer gets things done. Everything from memory allocation in the depths of operating system, to the inner workings of an RDBMS, to how networking stack manages to send data from one place to another, all computers rely on fundamental data structures and algorithms, so understanding them better makes one understand the computer better.

In this course, the Data Structures and algorithms have been implemented using Object Oriented Approach with C++.Object-oriented programming (OOP) is a programming language model in which programs are organized around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behaviour. OOP approach enables a programmer to deal with real world entities. This opposes the historical approach to programming where emphasis was placed on how the logic was written rather than how to define the data within the logic.

Objective
