What are some of the CASE tools available for RDBMS?

CASE (Computer-Aided Software Engineering) tools are software applications that support various stages of the software development life cycle. In the context of relational database management systems (RDBMS), there are several CASE tools available that can aid in database design, implementation, and maintenance. Here are some examples:

1. ERwin Data Modeler: ERwin is a popular CASE tool used for database design and modeling. It allows users to create and modify entity-relationship diagrams (ERDs), and generates SQL scripts for database implementation. ERwin also includes features for database version control, data dictionary management, and database documentation.
2. SQL Power Architect: SQL Power Architect is an open-source CASE tool that supports database design and modeling for various RDBMS platforms, including Oracle, MySQL, and SQL Server. It provides a graphical interface for designing ERDs, and generates SQL scripts for database implementation. SQL Power Architect also includes features for data profiling, data lineage analysis, and database documentation.
3. Oracle SQL Developer Data Modeler: Oracle SQL Developer Data Modeler is a CASE tool specifically designed for Oracle databases. It provides a graphical interface for designing ERDs, and generates SQL scripts for database implementation. SQL Developer Data Modeler also includes features for database version control, data dictionary management, and database documentation.
4. Toad Data Modeler: Toad Data Modeler is a CASE tool that supports database design and modeling for various RDBMS platforms, including Oracle, SQL Server, and MySQL. It provides a graphical interface for designing ERDs, and generates SQL scripts for database implementation. Toad Data Modeler also includes features for database version control, data dictionary management, and database documentation.
5. DbWrench: DbWrench is a multi-platform CASE tool that supports database design and modeling for various RDBMS platforms, including MySQL, Oracle, and SQL Server. It provides a graphical interface for designing ERDs, and generates SQL scripts for database implementation. DbWrench also includes features for database version control, data dictionary management, and database documentation.

These are just a few examples of the CASE tools available for RDBMS. Each tool has its own features, strengths, and limitations, and the choice of tool depends on the specific needs and requirements of the database project.

A case tool is a class of software that automates the activities involved in various life cycle phases.
For example, when establishing the functional requirements of a proposed application, prototyping tools can be used to develop graphic models of application screens to assist end users to visualize how applications will look after development. Subsequently, system designers can use automated design tools to transform the prototyped functional requirements into detailed design documents.
Programmers can then use automated code generators to convert the design documents into code. Automated tools can be used collectively, as mentioned, or individually. For example, prototyping tools could be used to define application requirements that get passed to design technicians who convert the requirements into detailed designs in a traditional manner using flowcharts and narrative documents .

As you do more with the UML and the programming gets increasingly mechanical, it becomes obvious that the programming should be automated. Indeed, many CASE tools do some form of code generation, which automates building a significant part of a system. Eventually, however, you reach the point at which all the system can be specified in the UML, and you reach UML as programming language. In this environment, developers draw UML diagrams that are compiled directly to executable code, and the UML becomes the source code. Obviously, this usage of UML demands particularly sophisticated tooling.
