Data Modeling is a technique for organizing and documenting a system’s data. Data modeling is also referred to as database modeling. An entity-relationship diagram (ERD) is a simple example of data modeling.
In this “Data Modeling and Analysis – System Analysis and Design” you will learn about the following topics:
- What is Data Modeling?
- System Concepts for Data Modeling
- Entities, Attributes, Relationships
- The Process of Logical Data Modeling
- Strategic Data Modeling, Data Modeling During System Analysis, Data Modeling during Systems Design, Automated Tools for Data Modeling
- How to Construct Data Models
- Entity Discovery, The Context Data Model, The Key-Based Data Model, Generalize Hierarchies, Develop A Fully Attributed Data Model
- Analyzing the Data Model
