5. Advanced data management: UniDAC supports advanced features like batch operations, transactions, and more for efficient data manipulation.
6. Connection pooling: UniDAC supports connection pooling, which allows applications to reuse database connections efficiently, improving performance and scalability.
7. Cached updates: UniDAC enables applications to cache updates locally and apply them to the database later, reducing the number of round trips to the database server.
8. Design-time support: UniDAC includes design-time components for managing connections, managing connections, configuring data access, and creating data-aware components, which simplifies the development process.

9. Local SQL support: UniDAC allows executing SQL commands against in-memory datasets, even for databases that don’t natively support SQL. This feature can be helpful for filtering, sorting, and aggregating data locally without the need for additional round trips to the database server.
10. Wide range of data access components: UniDAC includes components for standard data access, such as TUniQuery, TUniTable, and TUniStoredProc, as well as specialized components for specific databases, like TUniOracle, TUniSQLServer, and TUniMySQL.
11. Extensibility: UniDAC has a modular architecture that allows developers to create custom data access components or extend existing ones to support additional databases or features.

In summary, UniDAC is a versatile library that provides a unified and efficient way to work with various databases in Delphi, C++Builder, and Lazarus environments. Its universal data access components, high-performance design, and cross-platform support make it an attractive choice for developers building database-driven applications.
