System Analysis and Design Flashcards

Flashcards covering the fundamentals of system analysis and design, including key concepts, methodologies, and tools.

System Analysis

A process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components.

Systems Analyst

A person who uses analysis and design techniques to solve business problems using information technology.

Structured Analysis

A development method that allows the analyst to understand the system and its activities in a logical way.

Tools used during Structured Analysis

What are Data Flow Diagrams, Data Dictionary, Decision Trees, Decision Tables, Structured English, and Pseudocode?

Software Requirements Specification (SRS)

A document that describes the nature of a project, software, or application.

Components of System Design

Quality, Timeliness, and Cost-Effectiveness.

Essential components of system design

Quality, Timeliness, Cost-Effectiveness

Inputs of System Design

Statement of work, Requirement determination plan, Current situation analysis

Outputs of System Design

Infrastructure and organizational changes for the proposed system, A data schema, Metadata, Function hierarchy diagram, Pseudocode, A prototype

Stages of System Design

Requirements determination, Requirements specifications, Feasibility Analysis, Final Specifications, Hardware study, System Design

Data Modeling Techniques

Conceptual, Relational, Object Oriented

Types of System Design

Logical, Physical, Architectural, Detailed.

Data Modeling

The process of creating a data model for the data to be stored in a Database.

Types of Advance Design modeling

Entity Relationship (E-R) Model and UML (Unified Modeling Language)

File Organization Methods

Serial, Sequential, Direct, Indexed

File Access Methods

Sequential and Direct

System Security Controls

Privacy and Integrity

System Control Measures

Backup, Physical Access, Logical

Structured Design Concepts

Input, Output, User interface, Modularization

Security Controls

Safeguards or countermeasures to avoid, detect, counteract, or minimize security risks.

Integrity Models

Keep data pure and trustworthy by protecting system data from intentional or accidental changes.

Access Control

Regulates who or what can view or use resources in a computing environment.

Physical Access Control

Limits access to campuses, buildings, rooms and physical IT assets

Logical Access Control

Limits connections to computer networks, system files and data.

System Implementation Procedures

Program Development, Quality Assurance, Data Conversion

Types of System Testing

Software, Unit, Integration, Usability

Deployment Procedures of the System

Installation, Documentation, Training, Maintenance

Program Development

The process of formulating, improving, and expanding educational, managerial, or service-oriented work plans.

Quality Assurance

Defines the quality standards for the project and determines how they are satisfied.

Data Conversion

The process of translating data from one format to another while retaining its viability and quality.

Framework

A set of components working together so they address a number of problems in one or more domains.

Model-Driven Architecture (MDA)

A type of approach to software design, development, and implementation that focuses on models to work with systems.

Agile Software Development

Iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams.

Abstraction

The act of representing essential features without including the background details or explanations.
