I've completely neglected this piece due to a tightly scheduled phase of a project. That's over and so will be this. In part 1 & part 2 we envisioned an architectural model for data entities that exhibit data related behavior without using JPA and explained how to track and report changes. In this part, we'll look into the ways we can populate and validate these objects. Data Population

In the introduction episode, I wrote about an Idea for an architectural model to create data entities that exhibit data related behaviors particularly Population, Validation, and Tracking and Reporting Changes without using JPA. In this episode we take a closer look at the model and the implementation of "tracking and reporting changes". Basics In this model, entities are divided into two

When C# is my technology of choice to design a middle tier (and I have the chance to work it out from scratch) I often end up using an open source architectural framework called CSLA.NET (This post isn't about C# or CSLA though. Indulge me a few moments as I try to set the context.). Created by +Rockford Lhotka, CSLA.NET essentially helps you with building an object-oriented business layer

I decided to write this post when I came across a website with a background image in its homepage and the header part of each internal page! And not just any image, but children's hand-drawn ones (a skeuomorph of children's drawing notebook). Although a trend out of fashion, I'd like to use this opportunity to explain why this isn't such a good idea from both usability and technical points

IDC's press release on April 10th suggests a decline of almost 14% in PC shipments in the first quarter of 2013 compared to the same quarter in 2012 and, at the same time, the increase in the sale of tablets and smart phones. It also suggests that even the introduction of Windows 8 hasn't made any difference and, on the contrary, has slowed the market. The report continues to explain why:

One of the companies I'm associated with is going through a major website redesign project. My responsibilities, as an architect, are divided between back-end duties (e.g.: design reviews of enterprise components) and participating in review sessions of many artifacts of Information Architecture and Content Strategy delivered by an external vendor.

Recently I have been working with a development team on various sub-projects of a bigger project. New features were being introduced in form of new sub-projects and the team was eager to adopt Agile development. So we decided to do so in one of those sub-projects in order to get them familiar with the concept and hopefully apply it to all the future development projects.I’ll briefly elaborate the

I wanted to write a quick one about the IT Architect Regional Conference SEA which was over yesterday. One of the questions I got a few times was that how one becomes a software architect.Well, the quick answer would be that you need to realize that architecture design imposes different kinds of challenges compared to software development. If you become a senior developer it doesn't necessarily

Here is the link to the conference home page:http://www.iasahome.org/web/itarc/KLThe topic's title in the website is "Managing Changes and Mitigating Risks in Software Development" which is not correct.

The benefits of Agile development approaches in which developing software applications iteratively and incrementally is an important and inevitable principal are questionable if deliverables produced during the project do not introduce any business value.If a development project doesn’t deliver business values incrementally iteration by iteration then it’s executed in a value-neutral setting in

I hope can keep it up.This is the direct link and this is a link through IASA's content repository.I also figured out that you can not post any comment on the IASA's forum unless you are a member.

HelloI’ve recently joined a BPO (Business Process Outsourcing) provider company which gives me an excellent opportunity to put my knowledge of SOA and SaaS in action. So I guess that’s what is going to shape my future posts here.Well, here is one.SDPs (Service Delivery Platforms) are playing almost the same role for delivering Software as a Service (SaaS) as Operating Systems do in desktop

What would be your answer to the above question? Use-Case driven, Test-Driven, Scenario-Driven, or perhaps Feature-Driven. People often talk about these drivers as the only forces steering projects and shaping project plans. But in fact these mechanisms are used for defining and managing projects’ scopes. I believe without Iterative and Incremental Development (IID) approach you won’t have the

A while ago I was reading an article at Dr.Dobb’s Journal from Scott Ambler (see his profile at IBM) here. I suggest you guys to read it as well if you haven’t yet. It actually points out a hidden impediment which is an obstacle to many of software development teams that try to exercise IID (Iterative and Incremental Development); the lawyers who say NO!

Loosely coupled sort of integrations such as SOA are common since business processes are becoming more dynamic and object-based development platforms are expanding. But I don’t think the era of tightly coupled systems is over yet for reasons such as lower integration cost or having stateful distributed objects (rare but valid requirement). The objective of this post isn't to debate the pros

In part 1 of this series Row (Record) Level Security was introduced and part 2 depicted its implementation in Oracle database. I'd like to start the last part by answering one of the questions I was asked: "what's the point of doing this much configuration in an application that users never see the database? Essentially, application layer's control should suffice." To be pragmatic, I'd say not

In the first episode we briefly introduced Row Level Security. In this part I’m going to show you how to implement it in an Oracle 10g database. Oracle 8i introduced a feature called VPD (Virtual Private Database); also known as Fine Grained Access Control that provides powerful row-level security capabilities. VPD works by modifying the SQL commands to present a partial view of data to the

In this 3 parts series I intend to explain what Row Level Security in database management is and how to implement it in Oracle and SQL Server. In almost all database management systems the level at which information is controlled extends only to a certain level of granularity. In some scenarios, however, there is a requirement to control access at a more granular level. A list of patients, for

If you are an Oracle expert or follower, you’ve probably been following Oracle’s Open World and its news. One of the biggest one was Oracle’s announcement of distribution and support of Red Hat Linux on October 26. This made the Linux Magazine to say “Oracle was predicted to make a big Linux announcement this week and you would be hard pressed to make a bigger one than this”.But I believe the

I'd like to write about something a little bit different from the other posts, Iterative Development.Well, it may sounds easy and obvious. That’s what I thought when I heard it for the first time. But usually when I ask this simple question that what Iterative Developments is, I get a vague answer. Thus, I decided to write about it.I use to think the most important part of development is to get

In this post I'd like to write about Oracle's Shared Pool and the way it is being used and also introduce a package named "DBMS_SHARED_POOL". Every Oracle Instance has one big memory structure called SGA (System Global Area). It can vary in size depending on the server's memory capabilities.SGA is divided into various pools and one of its critical pieces is Shared Pool. Critical in term of

In part 1 and part 2 of this series we introduced TFS and its architecture. I intended to close this series by writing about other aspects of team development using TFS. But a colleague pointed out that TFS deployment is not as easy as it looks to many. So I dedicate this post to the topic of installation.  You can deploy TFS in two ways, single server or double server. Among reasons to use
