Hardware and Environmental Requirements
In most cases, it’s the prevailing hardware that might place constraints upon the CASE tool choice. Thus, rather than process hardware necessities for a CASE tool, the task at hand becomes to suit an associate degree optimum configuration of the CASE tool within the existing hardware capabilities. Therefore, it is often emphasized to choose the foremost optimum CASE tool configuration for a given hardware configuration.
- The heterogeneous network is one instance of distributed surroundings and this will be decided for illustration because it is a lot of in style because of its machine freelance options. The CASE tool implementation in the heterogeneous network makes use of the client-server paradigm. The multiple purchasers WHO run different modules access the knowledge wordbook through this server. the info wordbook server could support one or a lot of comes. although it’s doable to run several servers for various comes however distributed implementation of information wordbook isn’t common.
- The toolset is integrated through the info wordbook that supports multiple cores, multiple users operating at the same time, and permission to share data between users and comes. the info wordbook provides a consistent read of all project entities, e.g., a knowledge record definition and its entity-relationship diagram be consistent. The server ought to depict the per-project logical read of the info wordbook. this suggests that it ought to permit backup/restore, copy, cleansing of a part of the info wordbook, etc.
- The tool ought to work satisfactorily for an optimum doable variety of users operating at the same time. The tool ought to support multi-windowing surroundings for the users. this is often vital to modify the users to work out quite one diagram at a time. It additionally facilitates navigation and change from one half to the opposite.
