For each unit, learn the definition, understand the process, practise one example, and finish by explaining the concept in your own words. Use the model questions after completing the unit notes.

Unit-by-unit notes

01

Database concepts, data models, and DBMS architecture

Revise the definition, components, workflow, common examples, and practical use of database concepts, data models, and dbms architecture. Relate it to a small problem or case study from Database Management System.

  • Define the key terms and identify the main components.
  • Draw or describe the workflow, architecture, formula, or process where relevant.
  • Connect the idea to a practical BCA example and revise common advantages or limitations.
02

Entity-relationship modelling and relational schema design

Revise the definition, components, workflow, common examples, and practical use of entity-relationship modelling and relational schema design. Relate it to a small problem or case study from Database Management System.

  • Define the key terms and identify the main components.
  • Draw or describe the workflow, architecture, formula, or process where relevant.
  • Connect the idea to a practical BCA example and revise common advantages or limitations.
03

Relational algebra, SQL queries, views, and integrity constraints
