Reasons for using CASE tools
The primary reasons for employing a CASE tool are:
to extend productivity
to assist turn out higher quality code at a lower price
CASE Environment
Although individual CASE tools square measure helpful, the true power of a toolset is often completed only this set of tools square measure integrated into a typical framework or setting. CASE tools square measure characterized by the stage or stages of package development life cycle that they focus on.
CASE Environment
CASE Environment
A CASE environment facilitates the automation of the in small stages methodologies for package development. In distinction to a CASE environment.
A programming environment is an Associate in a Nursing integrated assortment of tools to support solely the cryptography part of package development.
CASE Architecture
Types of CASE Tools
Analysis Tools:
It focuses on inconsistent, incorrect specifications involved in the diagram and data flow. It helps in collecting requirements, automatically check for any irregularity, imprecision in the diagrams, data redundancies, or erroneous omissions.
(i) Accept 360, Accompa, CaseComplete for requirement analysis.
(ii) Visible Analyst for total analysis.
Types of CASE Tools
Diagramming Tools:
�It helps in diagrammatic and graphical representations of the data and system processes. It represents system elements, control flow and data flow among different software components and system structures in a pictorial form. For example, Flow Chart Maker tool for making state-of-the-art flowcharts.
Types of CASE Tools
Computer Display and Report Generators:
These help in understanding the data requirements and the relationships involved.
Code Generators:
It aids in the auto-generation of code, including definitions, with the help of designs, documents, and diagrams.
Types of CASE Tools
Central Repository:
It provides a single point of storage for data diagrams, reports, and documents related to project management.
Documentation Generators:
It helps in generating user and technical documentation as per standards. It creates documents for technical users and end users. For example, Doxygen, DrExplain, Adobe RoboHelp for documentation.
Advantages
As the special emphasis is placed on the redesign as well as testing, the servicing cost of a product over its expected lifetime is considerably reduced.
The overall quality of the product is improved as an organized approach is undertaken during the process of development.
Chances to meet real-world requirements are more likely and easier with a computer-aided software engineering approach.
Advantages
CASE indirectly provides an organization with a competitive advantage by helping ensure the development of high-quality products.
It provides better documentation.
It improves accuracy.
It provides intangible benefits.
It reduces lifetime maintenance.
It is an opportunity to non-programmers.
Advantages
It impacts the style of working of the company.
It reduces the drudgery in software engineer’s work.
It increases the speed of processing.
It is easy to program software.
Disadvantages
Disadvantages
Learning Curve: In most cases, programmers’ productivity may fall in the initial phase of implementation, because users need time to learn the technology. Many consultants offer training and on-site services that can be important to accelerate the learning curve and to the development and use of the CASE tools.
Key points
A CASE environment facilitates the automation of the in small stages methodologies for package development. In distinction to a CASE environment.
The primary reasons for employing a CASE tool are to extend productivity to assist turn out higher quality code at a lower price.
