Study Notes
Entity-Relationship (ER) Modeling
- The primary objective of ER modeling in database design is to visually represent the structure of a database, allowing designers to conceptualize and organize data into entities and relationships.
System Development Life Cycle (SDLC)
- The stage of the SDLC that involves building a working model of the database system is prototyping.
Database Management System (DBMS) Selection
- The main purpose of selecting a suitable DBMS for the database system is to choose a DBMS that meets the functional and performance requirements of the database.
Requirement Collection
- The stage of Requirement Collection in database design involves gathering and documenting the functional and non-functional requirements of the database system from stakeholders.
ER Modeling with UML
- A key aspect associated with ER modeling using Unified Modeling Language (UML) is the use of class diagrams to represent entities and their relationships.
Test your knowledge about using Entity-Relationship (ER) modeling in database design, understanding the basic concepts associated with the ER model, displaying ER model using Unified Modeling Language (UML), resolving problems such as connection traps, and building an ER model from a requirements specification.
