All Free Software Engineering MCQs with Answers

• A. Non-redundant data storage
• B. Data independence
• C. Data dependence
• D. Ad Hhoc data queries and reports

Explanation: Data independence separates CASE tools and applications from the details of physical storage, so hardware or storage changes do not…

• A. Reverse engineering specification tools
• B. Code restructuring and analysis tools
• C. Test management tools
• D. online system re-engineering tools

Explanation: Online system re-engineering tools support the analysis and modification of existing online database systems.

• A. Non-redundant data storage
• B. Data independence
• C. Transaction control
• D. Ad Hoc data queries and reports

Explanation: Non-redundant data storage keeps each object in one repository location while allowing multiple CASE tools to access it.

• A. Document standardization
• B. Data integrity
• C. Information sharing
• D. Data/data integration

Explanation: Document standardization results when repository objects are defined consistently and can be used to generate software engineering…

• A. Dynamic measurement
• B. Data acquisition
• C. Test management
• D. Cross-functional tools

Explanation: Test management tools support the planning, execution, monitoring, and control of testing activities within a CASE environment.

• A. Dynamic analysis
• B. Client/Server
• C. Re-engineering
• D. Test management

Explanation: Client/server environments require tests for both the graphical user interface and communication across the network between client and…

• A. project database
• B. system database
• C. analysis and design tools
• D. prototyping tools

Explanation: A project database is the CASE repository built on database management software, storing the information shared by project tools.

• A. Data acquisition
• B. Dynamic measurement
• C. Cross-functional tools
• D. Simulation

Explanation: Cross-functional tools span multiple CASE categories instead of serving only one specialized activity.

• A. Analysis and design tools
• B. Tool kit
• C. Screen painters
• D. PRO/SIM tools

Explanation: Screen painters let engineers rapidly arrange and specify screen layouts for interactive applications, much like a visual form designer.

• A. A collection of useful tools that will help in every step of building a product
• B. An organized layout that enables tools to be found quickly and used efficiently
• C. A skilled artisan who understands how to use the tools in an effective manner
• D. All of the mentioned

Explanation: A CASE environment combines useful development tools, an organized interface or repository for accessing them, and skilled people who…

• A. data analysis
• B. directionality
• C. data extraction
• D. client applications

Explanation: Data analysis examines extracted data items, objects, relationships, and flows to recover the structures already present in a system.

• A. Re-factoring
• B. Restructuring
• C. Forward engineering
• D. Both Re-factoring and Restructuring

Explanation: Restructuring changes a system's representation while preserving its essential behavior, and refactoring is a source-code-focused form of…

• A. GUI
• B. Database
• C. Source code
• D. All of the mentioned

Explanation: Reverse engineering works backward from implementation to recover design and specifications, most commonly using the system's source code.

• A. candidate keys
• B. interface
• C. database structure
• D. none of the mentioned

Explanation: A behavioral model can be inferred by observing how the existing interface responds to external inputs and actions.

• A. Build an initial object model
• B. Determine candidate keys
• C. Refine the tentative classes
• D. Discover user interfaces

Explanation: Recovering an existing data model involves building an object model, finding candidate keys, and refining classes.

• A. GUIs
• B. Candidate keys
• C. Object model
• D. All of the mentioned

Explanation: Graphical user interfaces have become standard for most modern computer-based products because they provide familiar visual interaction.

• A. interactivity
• B. completeness
• C. abstraction level
• D. direction level

Explanation: The abstraction level indicates how sophisticated the recovered design information is, ranging from low-level code details to higher-level…

• A. extract abstractions
• B. renovation
• C. reclamation
• D. both renovation and reclamation

Explanation: Forward engineering moves from recovered or redesigned abstractions toward a working implementation and is also described as renovation or…

• A. restructure code
• B. directionality
• C. extract abstractions
• D. interactivity

Explanation: Extracting abstractions is the central reverse-engineering activity: engineers infer higher-level designs, structures, and behavior from…

• A. real-life operating system
• B. real-time operating system
• C. real-time operating software
• D. real-life operating software

Explanation: RTOS stands for real-time operating system, designed to respond to events within specified timing constraints.
