Embarcadero released to introduce major compiler enhancements, including C++17 support for Win32, expanded Win64 optimization, and modernized Object Pascal features. To maximize these IDE enhancements, your data access components must be precisely aligned with the compiler's memory management and underlying RTL (Run-Time Library).

Performance Benchmark Considerations
When the job completed, the manager asked the inevitable: “Why do you keep these installers? Why not update everything to the latest?” Viktor looked at the icon on his desktop and answered, “Because sometimes the world asks for what it used to be.” He meant more than software. Some clients needed stability; some data required the exact tools used when it was born.

RAD Studio 10.3 Rio (released 2018-2019) was a landmark release introducing features like:
The core philosophy of UniDAC is abstraction. Instead of using vendor-specific components (like FireDAC’s multiple drivers or direct ADO connections), UniDAC provides a set of common components— TUniConnection , TUniQuery , TUniTable , and TUniScript —that work identically regardless of the underlying database. For RAD Studio 10.3 Rio developers, this means writing a single data module that can connect to Oracle, SQL Server, MySQL, PostgreSQL, SQLite, InterBase, or Firebird with only a change in the connection parameters.
UniDAC is engineered to be a solution. By using a powerful macros engine and a unified API, developers can switch the underlying database (e.g., from SQLite to SQL Server) by changing a single line of code. Universal Data Access Components - Features - Devart
