Computer-Aided Software Engineering (CASE) Tools Which of the following is NOT a relevant feature of CASE tools used in software and database design?
-
AThe ability to help draw data models using entity-relationship notations
-
BThe ability to generate code
-
CAn information repository
-
DAccess to a database via the Internet
-
ESupport for forward and reverse engineering
Answer
Correct Answer: Access to a database via the Internet
Explanation
Introduction:CASE (Computer-Aided Software Engineering) tools streamline the systems development life cycle by supporting modeling, documentation, and automation. This question tests whether you can identify a feature that falls outside the typical scope of CASE capabilities.
Given Data / Assumptions:
- CASE tools focus on analysis, design, modeling, documentation, and sometimes code generation.
- They maintain artifacts in an information repository to ensure consistency.
- Connectivity to a database over the Internet is primarily an application/runtime concern, not a design-automation feature.
Concept / Approach:Common CASE capabilities include diagramming (ER models, UML), repository management, forward engineering (generate schemas/code), and reverse engineering (read existing schemas/code). By contrast, Internet database access relates to application-level connectivity using drivers, middleware, and network protocols rather than design automation.
Step-by-Step Solution:1) List core CASE features: modeling, repository, forward/reverse engineering, documentation, and sometimes code generation.2) Compare each option to those core features.3) “Access to a database via the Internet” pertains to runtime access patterns and network connectivity, not CASE tooling.
Verification / Alternative check:Survey well-known CASE products (for example, ER modeling tools). Documentation emphasizes modeling and engineering features rather than network data-access layers.
Why Other Options Are Wrong:
- ER notations: Core diagramming support.
- Code generation: Typical forward engineering outcome.
- Information repository: Central store for design artifacts and metadata.
- Forward and reverse engineering: Standard features of mature CASE tools.
Common Pitfalls:Confusing application/data-access concerns (drivers, APIs, middleware) with design-centric capabilities of CASE tools.
Final Answer:Access to a database via the Internet
