Types of Databases: Relational vs. Non-Relational
Relational Databases (RDMS)
Definition: Organize data in a structured format using tables, with each table consisting of
columns and rows.
Example: MySQL, Oracle, Microsoft SQL Server.
Advantages: Well-defined schema, data integrity, and support for complex queries.
Non-Relational Databases (NoSQL)
Definition: Store data in a semi-structured or unstructured format, such as key-value
pairs, documents, or graphs.
Example: MongoDB, Cassandra, Redis.
Advantages: Flexibility, scalability, and high performance for large datasets.
