Database and System Development Quiz

Study Notes

Data Dictionary

A data dictionary is a centralized repository of metadata that provides a comprehensive description of data structures, relationships, and usage in a database management system.
It serves as a single source of truth for data definitions, facilitating data sharing, and ensuring data consistency across the system.

Project Management

Project management is essential in system development as it enables the delivery of projects on time, within budget, and to the required quality standards.
Effective project management ensures that all stakeholders are aligned with project goals, and that resources are allocated efficiently to meet project objectives.

Feasibility Assessment

A feasibility assessment is a critical step in system development that evaluates the practicality of a project, identifying potential risks, and determining its viability.
It helps to determine whether a project is worth pursuing, and whether it aligns with the organization's strategic objectives.

Low-Level vs. Procedural Languages

Low-level languages are close to machine language, requiring a deep understanding of computer hardware and architecture.
Procedural languages, on the other hand, are high-level languages that focus on procedures and functions, abstracting away hardware details.

Object-Oriented Programming (OOP) Languages

Object-oriented programming languages offer benefits such as modularity, reusability, and ease of maintenance, making them ideal for complex application development.
OOP languages and application development tools provide a framework for organizing and structuring code, enabling developers to create robust, scalable, and maintainable software systems.
