Lower CASE tools support the back-end activities of a development project.

These CASE tools support, specifically, the modelling activities vital to the analysios and design stages of a development project

An upper CASE tool supports front-end activities that focus upon capturing analysis and design information in the early stages of systems development.

These terms refers refers to the functions supported by the tool

CASE tools are often classified as upper CASE tools, lower CASE tools or Integrated CASE (I-CASE) tools.

By automating code generation (to a certain degree), testing and version/change control activities Automating tedious and error-prone analysis and design activities thus proving consistency between viewsĥ. By improving communications between the designers and end-users using graphical representations of the system designĤ. Providing a central repository for all design components and making them available to all the design teamģ. Enforcing a standard development methodology and design principleĢ.

Code generators and documentation generators utilising the deliverables of the modeling activities to develop working systemsĢ.0 How CASE tools try to increase quality and productivityġ.

Analysis and cross-referencing tools to ensure integration of model views.

Reporting facilities ranging from project management statistics through to design inconsistencies.

Data dictionaries providing a central repository for all definitions used by the development team.

Screen and report generators to assist in designing the dialogue/presentation of the proposed information systems.

Automated graphics facilities for producing charts and diagrams in support of modeling activities.

Generally, a CASE tool environment may be expected to provide the following:.

It also refers to methods for the development of information systems together with automated tools that can be used in the software development process.Computer-aided Software Engineering (CASE), in the field software engineering is the scientific application of a set of tools and methods to software which results in high-quality, defect-free, and maintainable software products.CASE tool is an acronym for ‘Computer Aided Software engineering’ – the automation of step-by-step methodologies for software and systems development to reduce the amount of repetitive work the developer needs to do.It manages all operations of library database. Librarian Class – It manages all operations of Librarian.It is central part of organization for which software is being designed. It manages all operations of Library Management System. All these relationships are shown in diagram.Ĭlass Diagram for Library Management System simply describes structure of Library Management System class, attributes, methods or operations, relationship among objects. Many books are associated with one librarian and this represents many-to-one or one-to-many type of relationship. One user has only one account that is denoted by 1 and this represents a one-to-one type of relationship. We can see in diagram many users are associated with many books denoted by * and this represents a many-to-many type of relationship. For denoting one element we use 1, for zero elements we use 0, and for many elements we use *. These relations can be one-to-one, many-to-many, and many-to-one or one-to-many. Multiplicity means that number of elements of a class is associated with another class. All of these, share a relationship and these relationships are known as aggregate relationships. Further, for “Account” class, “User” is a superclass. These classes are User, Book, and Librarian as shown in diagram.
