The solidDB Application Programming Interface, also known as solidDB SA, is a low level C-language client library that you can use to access solidDB database management products. solidDB SA is a layer that resides internally in solidDB products. Normally, the use of an industry standards-based interface, such as ODBC or JDBC, is recommended. However, in environments with heavy write load (batch inserts and updates), solidDB SA can provide a significant performance advantage.

Additionally, the solidDB SA interface provides functions that can generate geohash values in order to enhance performance in spatial queries, see solidDB geohash functions.
