Coding Rules for RDBMS:

Following best practices when designing a relational database is crucial for efficiency, integrity, and maintainability.

Key Rules:
  • Normalization: Organize your tables to reduce data redundancy and improve data integrity. Aim for at least 3rd Normal Form (3NF) for most applications. This involves ensuring that data is stored logically and without unnecessary duplication.
  • Primary Key Selection: Every table should have a primary key that is unique, never null, and stable (it shouldn't change over time). This key uniquely identifies each record.
  • Foreign Key Constraints: Use foreign keys to link related tables and enforce referential integrity. This ensures that a record in one table cannot reference a non-existent record in another.
  • Indexing: Create indexes on columns that are frequently used in `WHERE` clauses or `JOIN` conditions to speed up query performance. Be mindful not to over-index, as it can slow down data modification operations (INSERT, UPDATE, DELETE).
  • SQL Best Practices: Write clear and efficient SQL. Avoid using `SELECT *`; instead, specify the exact columns you need. Use parameterized queries to prevent SQL injection attacks.
