DT Softwares are based on the Model-View-Controller development pattern. MVC is a software approach that separates application logic from presentation. In practice, it permits your web pages to contain minimal scripting since the presentation is separate from the PHP scripting.

    * The Model represents your data structures. Typically your model classes will contain functions that help you retrieve, insert, and update information in your database.
    * The View is the information that is being presented to a user. A View will normally be a web page, but in DT Softwares , a view can also be a page fragment like a header or footer. It can also be an RSS page, or any other type of "page".
    * The Controller serves as an intermediary between the Model, the View, and any other resources needed to process the HTTP request and generate a web page.

Software as a Service (SaaS, typically pronounced 'sass') is a new model of software deployment whereby a provider licenses an application to customers for use as a service on demand.

Saas will ease the burden of Total Cost of Ownership (TCO) like software licensing, hardware & human resource such as IT. This will help business owners to focus thier business to their products & services not to the Computer Technology which they acquire from the software vendor.

Curtain Raiser
As in any other engineering disciplines, software engineering also has some structured models for software development. This document will provide you with a generic overview about different software development methodologies adopted by the contemporary software firms. Before we get into the of the different models, we shall have a brief insight about the basics that spread throughout these models.

Like any other engineering products, software products are oriented towards customers. It is either market driven (or) it drives the market. Customer Satisfaction was the buzzword of the 80's. Customer Delight is today's buzzword and Customer Ecstasy is the buzzword of the new millennium. Products that are not customer (user) friendly have no place in the market although they are engineered using the best technology. The interface of the product is as crucial as the internal technology of the product.
