Common Pitfalls to Avoid

Avoid over- normalization, which can lead to complex queries and accepted performance. Also, refrain from using excessive indexes, as they can slow down spise operations. Regularly reviewing and optimizing these schema helps prevente these issues.

Summary of Key Practices

  • Normalize data to reduce reduccy
  • Use approate data type for each column
