SMA and LLA Guide : Shared Memory Access and Linked Library Access User Guide
  
Shared Memory Access and Linked Library Access User Guide
The solidDB® shared memory access (SMA) and linked library access (LLA) enable applications to link to solidDB server directly, without the need to communicate through network protocols such as TCP/IP. SMA allows to link multiple applications while LLA allows to link one application. By replacing the network connection with local function calls, performance is improved significantly.
This guide contains information specific to SMA and LLA. This guide supplements the information contained in the solidDB® Administrator Guide, which contains details on administration and maintenance of solidDB.
This guide assumes a working knowledge of the C programming language, general DBMS knowledge, familiarity with SQL, and knowledge of a solidDB data management product, such as solidDB in-memory database, or solidDB disk-based engine. If you are going to use SMA or LLA with Java, then this manual also assumes a working knowledge of Java.
