Efficient database management improves scalability, security, and performance. Using normalized databases, indexing, and partitioning speeds up queries. ORM frameworks like Entity Framework Core (EF Core) or Dapper simplify data access while enforcing best practices. Stored procedures, parameterized queries, and transactions prevent SQL injection and enhance security. Dot Net development database connection pooling, caching mechanisms, and proper indexing strategies optimize query performance. Implementing database versioning with Flyway or Liquibase ensures seamless updates. Backup automation, disaster recovery planning, and role-based access controls ensure data integrity. These practices enable efficient and high-performing data management.
