Data Modelling Online Training FAQ'S

What is Data Modelling, and why is it important?

Data Modelling is the process of creating a visual representation of an information system’s data structure and relationships. It helps define how data is stored, connected, and accessed.
Importance:

Ensures data consistency and accuracy
Simplifies database design and maintenance
Improves communication between business and technical teams
Supports scalability and performance optimization

What are the different types of Data Models?

There are three main types of data models:

Conceptual Data Model: High-level design focusing on entities and relationships.
Logical Data Model: Defines attributes, keys, and relationships in detail without database-specific implementation.
Physical Data Model: Represents how the data will be stored in the database, including tables, columns, indexes, and constraints.

What is Normalization, and why is it used?

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It divides large tables into smaller, related ones.
Common Normal Forms: 1NF, 2NF, 3NF, and BCNF.
Normalization ensures efficient data storage and simplifies updates or deletions without anomalies.

What is the difference between OLTP and OLAP Data Models?

OLTP (Online Transaction Processing): Used for daily operations; focuses on fast inserts, updates, and queries. It uses normalized data models.
OLAP (Online Analytical Processing): Used for analytics and reporting; focuses on query performance. It uses denormalized or dimensional data models (Star/Snowflake schema).

What are Star Schema and Snowflake Schema in Data Warehousing?

Star Schema: A central fact table connected to multiple dimension tables. Simple and easy to query.
Snowflake Schema: A more complex version of the star schema where dimension tables are normalized into multiple related tables. It saves storage but increases query complexity.
