Common Limitations or Challenges
This guide focuses on the *analysis* phase of database development. It does not cover the detailed steps of database *design*, implementation using specific database management systems (DBMS), or advanced topics like query optimization. While it introduces key terminology, it doesn’t provide hands-on coding exercises or practical case studies with pre-built solutions. It assumes a basic understanding of general system development concepts.
