Master the Fundamentals of SDLC

Overview of System Development Life Cycle (SDLC), Database Life Cycle (DBLC), and Conceptual Design

• SDLC is the process of developing and maintaining information systems, which includes five phases: planning, analysis, detailed systems design, implementation, and maintenance.
• DBLC is the process of designing, implementing, and maintaining a database system, which includes five phases: initial study, database design, implementation and loading, testing and evaluation, and operation.
• Conceptual design is the first step in the design phase of DBLC, which uses data modeling techniques to create a model of a database structure that represents a real-world object.
• Business rules are used to describe the main and distinguishing characteristics of the data as viewed by the company, and the model is run through a series of tests against end user data views, access rights, and security, among others.
• A module is an information systems component that handles a specific business function, which speeds up the development work and helps with implementation and application programming trouble spots.
• Physical design is the process of determining the data storage organization and data access characteristics of the database to ensure integrity, security, and performance.
• The physical design affects the accessibility of the data and the performance of the system as a whole, and it involves defining data storage organization, integrity and security measures, and performance measures.
• Database design strategies include top-down design, which involves the identification of different entity types and the definition of each entity attribute, and bottom-up design, which defines the attribute in the end groups them to form entities.
• Centralized design is typically simple and small database and can be successfully done by a single database administrator or by a small informal design team.
• Decentralized design has a considerable number of entities and complex relations on which very complex operations are performed.
• The operational life cycle of a system may be reduced due to rapid technological changes and costs of maintaining a system.
• SDLC and DBLC are essential for the development and maintenance of information systems and databases, and conceptual design is a crucial step in creating a model of a database structure that represents a real-world object.
