INTRODUCTION ABOUT LAB

CASE tools known as Computer-aided software engineering tools is a kind of component-based development which allows its users to rapidly develop information systems. The main goal of case technology is the automation of the entire information systems development life cycle process using a set of integrated software tools, such as modeling, methodology and automatic code generation. Component based manufacturing has several advantages over custom development. The main advantages are the availability of high quality, defect free products at low cost and at a faster time. The prefabricated components are customized as per the requirements of the customers. The components used are pre-built, ready-tested and add value and differentiation by rapid customization to the targeted customers. However the products we get from case tools are only a skeleton of the final product required and allot of programming must be done by hand to get a fully finished, good product.

Characteristics of CASE:

Some of the characteristics of case tools

It is a graphic oriented tool.

It supports decomposition of process.

Some typical CASE tools are:

Unified Modeling Language

Data modeling tools, and

Source code generation tools

Introduction to UML (Unified Modeling Language):

The unified modeling language (UML) is a standard language for writing software blue prints. The UML is a language for

Visualizing

Specifying

Constructing

Documenting

The artifacts of a software system:

UML is a language that provides vocabulary and the rules for combing words in that vocabulary for the purpose of communication.

A modeling language is a language whose vocabulary and rules focus on the concept and physical representation of a system. Vocabulary and rules of a language tell us how to create and real well formed models, but they don’t tell you what model you should create and when should create them.

Visualizing

The UML is more than just a bunch of graphical symbols. In UML each symbol has well defined semantics. In this manner one developer can write a model in the UML and another developer or even another tools can interpret the model unambiguously.

Specifying

UML is used for specifying means building models that are precise, unambiguous and complete. UML addresses the specification of all the important analysis, design and implementation decisions that must be made in developing and deploying a software intensive system.

Constructing

UML is not a visual programming language but its models can be directly connected to a variety of programming languages. This means that it is possible to map from a model in the UML to a programming language such as java, c++ or Visual Basic or even to tables in a relational database or the persistent store of an object-oriented database. This mapping permits forward engineering. The generation of code from a UML model into a programming language. The reverse engineering is also possible you can reconstruct a model from an implementation back into the UML.

Documenting

UML is a language for Documenting. A software organization produces all sorts of artifacts in addition to raw executable code. These artifacts include Requirements, Architecture, Design, Source code, Project plans, Test, Prototype, and Release. Such artifacts are not only the deliverables of a project, they are also critical in controlling, measuring and communicating about a system during its development and after its deployment.

Conceptual model of the UML:

To understand the UML, we need to form a conceptual model of the language and this requires learning three major elements.

The UML Basic Building Blocks.

The Rules that direct how those building blocks may be put together. Some common mechanisms that apply throughout the UML. As UML describes the real time systems it is very important to make a conceptual model and then proceed gradually.
