Question 1

When testing top-down designs, the ___ is utilized as a dummy module.

Accepted Answer

Stub module

Answer

In top-down testing, higher-level modules are tested first, and lower-level modules that are not yet developed or integrated are simulated. A 'stub module' is a dummy program unit used for this purpose; it provides a minimal implementation to allow the calling module to be tested, returning predefined values or performing basic actions. This enables incremental testing without waiting for all components to be complete.

Question 2

A thorough business process-driven approach for planning information systems is _____.

Accepted Answer

Business systems planning

Answer

Business Systems Planning (BSP) is a structured, top-down methodology developed by IBM for analyzing an organization's information needs and planning its information systems architecture. It focuses on identifying the business processes and the data required to support them, leading to a comprehensive and integrated plan for information systems development that is driven by business requirements.

Question 3

In data flow diagrams, the ________________ process describes the most detailed level of the flow.

Accepted Answer

Functional primitives

Answer

In Data Flow Diagrams (DFDs), 'functional primitives' represent the lowest level of decomposition for a process. These are processes that cannot be further broken down into more detailed subprocesses, indicating the fundamental, atomic operations within the system. They describe the most granular and detailed level of data transformation within the flow.

Question 4

URL is an acronym for _______.

Accepted Answer

uniform resource locator

Answer

URL is an acronym for Uniform Resource Locator. It is a specific type of Uniform Resource Identifier (URI) that provides a way to locate a resource on the internet, specifying its location and the mechanism for retrieving it (e.g., http://, ftp://). This standard format allows web browsers and other software to access resources across the network.

Question 5

How many tiers are there in the database's architecture?

Accepted Answer

3

Answer

Database architecture is commonly described using a three-tier schema architecture. These tiers are the external level (how users view the data), the conceptual level (the logical structure of the entire database), and the internal level (the physical storage structure). This three-level approach provides data independence, allowing changes at one level without affecting the others.
