An Example Of Computer-Aided Software Engineering
Often referred to as CASE, computer-aided software engineering is a process of creating complex programs to meet a wide range of requirements.
Its emphasis on redesign and testing reduces the servicing costs of a product over its lifetime. This organized process helps improve the overall quality of the product.
A clearer understanding of a product’s requirements, and the corresponding process of redesign and testing, can provide a competitive advantage.
Rational Rose is a tool for computer-aided software engineering that facilitates object-oriented analysis and design.
It allows users to create and manipulate UML model elements, exposing problems early in the development process.
Its tools are flexible, supporting both simple and complex software solutions. In addition, Rose supports use-case-driven object modeling.
To learn more, read on! This article will give you the low-down on Rose.
The Rational Rose tool includes four main views: the logical view, the object model, the class model, and the state diagram.
Each view corresponds to a different phase of the software life cycle. The model views are accompanied by artifacts for the software development life cycle.
The logical view is a graphical representation of a computer system, providing a high-level overview of the entire software development process.
Rational Rose can facilitate both forward and reverse engineering. The forward engineering process involves creating skeletons from the Rose model.
Reverse engineering, on the other hand, allows users to re-use and update existing code. Rational Rose can also isolate deviations from the original design.
Users can create reflexive relationships among packages, classes, and reusable data.
By following the architecture-based best practices, the Rational Rose GUI can automatically create these relationships.
Using Rational Rose, software designers can visualize and document the structure of their applications.
Models can be created by blocking out classes and using case elements, objects, messages, and relationships.
Rational Rose also documents the diagram as it is built, while generating the code in the language of the designer.
This tool is used to design and modify large industrial-strength software systems. However, the use of Rational Rose is not limited to large enterprise projects.
Another example of computer-aided software engineering is a tool called MetaEdit+. MetaEdit+ is a better overall product, although both tools are very useful.
The latter includes domain-specific modeling. Rational Rose is a cross-platform solution.
This product has been ranked as the most widely used CASE tool among software developers. The product is also more expensive than MetaEdit+.
Computer-Aided Software Engineering (CASE) involves the use of tools and techniques to create high-quality, defect-free, and maintainable software products.
At the Separations Technology at Savannah River Site, the Computer Systems Engineering group has been using CASE tools to produce high-quality software products.
This paper details the acquisition and use of one such tool. It details how to use the CASE tools to create the software product described above.
A CASE tool is a software that is designed to facilitate the development and maintenance of a system. A CASE tool can range from a basic drawing program to a full-fledged debugger.
While CASE tools vary widely, most cover the full lifecycle of a system and provide automated support for all development activities.
For example, Together (TM) can be used to develop object-oriented systems.
This allows developers to use a common language to create multiple layers of code, each with a different purpose.
As a result, CASE tools can help engineers, analysts, and managers to build software products more efficiently and without risk.
Boyce-Codd Normal Form
In computer-aided software engineering, the third normal form is a weaker generalization than the Boyce-Codd Normal Form (3.5NF).
For example, in BCNF, the relation A-B is not a prime key if it has no subkey. But in 4NF, it is a prime key if A is a superkey for B.
The Boyce-Codd normal form is an extension of the 3NF. It is based on functional dependencies and considers all the candidate’s keys of a relation.
It has added constraints as well. Specifically, a relation is in the BCNF if it has at least one superkey X for every functional dependency it has.
Its other constraints are that all the determinants are Form (BCNF) candidates.
While the third normal form was first defined by Fagin in 1969, the Boyce-Codd normal form was not formally accepted until 1982.
The newer version was later considered a more rigorous standard. By comparison, the Boyce-Codd normal form contains many more restrictions than the 3NF.
By contrast, the Heath normal form is not limited to relational databases.
The Boyce-Codd normal form is stronger than the third normal form and deals with the issue of overlapping keys.
For example, the bookings and events relations are not repeated. If there are overlapping keys in a database table, it will be easier to find a solution.
The three-step process of transforming a database into a Boyce-Codd normal form is described in detail in the next section.
Computer-aided software engineering (CASE) was first developed by Albert F. Case Jr. in the late 1980s, as a way to improve the design process.
This software supports a variety of structured analysis methodologies, such as Ward-Mellor SA/SD and Warnier-Orr data-driven.
As the field matured, other companies and individuals started developing CASE products, including Accenture and Texas Instruments.
The benefits of computer-aided software engineering have been widely recognized since its inception in 1988.
IBM mainframe sites, among the largest and most lucrative computer customers, have made it a point to use these computer-aided software engineering tools to reduce application development costs.
Other companies, such as Dun & Bradstreet, have adopted this technology to create more efficient application designs.
Nevertheless, it remains to be seen whether this trend will continue. The benefits of CASE are many.
It increases the likelihood of meeting real-world requirements and ensures a defect-free final product.
CASE tools are expensive, however, and small software companies rarely invest in them.
Using these tools, however, can help reduce development costs and increase the quality of software.
However, the biggest disadvantage is the price of using these tools. For this reason, CASE tools aren’t suitable for small firms.
The main benefit of the online design aid is that it is easy to use and accounts for all important design variables.
It is based on a validated mathematical model and strikes the right balance between utility and accuracy.
The online design aid also has animation motion pictures to visualize gas concentration decay and oxygen replenishment.
It is not just about being useful but also making design decisions easier and more efficient.
