1. Core Idea of Data Modeling
- Data modeling is the process of creating a blueprint for how data will be stored and used.
- It involves defining data types, relationships among them, and how data can be grouped and organized.
- Omission of data in a data model leads to faulty reports and incorrect results.

2. Data Modeling Process
- The data modeling process involves six steps.
- Identify the entities: determine the things, events, or concepts represented in the data set.
- Identify key properties of each entity: these are attributes.

3. Conceptual Data Model and ER Model
- The conceptual model is developed independently of hardware and software specifications.
- Its focus is to represent data as a user will see it in the real world.
- The ER model is a conceptual design of a database that is easy to design the view of data.
