11 Database Schema Mistakes to Avoid

A well-designed database schema is crucial for efficient data warehousing and retrieval. It serves as a blueprint for organizing and categorizing data structures, making it easier for users to obtain actionable information. Poorly designed schemas can lead to confusion, difficulty in modification and maintenance, and wasted effort. Some common issues include outdated entity-relationship diagrams, inflexible schema designs, lack of pre-planning, inconsistent formatting, poor naming conventions, incorrect key field linking, overindexing, manual data normalization or cleansing, and inadequate documentation. To avoid these pitfalls, it's essential to follow best practices for database schema design.
