Introduction IBM Informix is a robust relational database management system (RDBMS) known for its high concurrency, low administrative overhead, and TimeSeries capabilities. However, its effectiveness in modern applications depends critically on the underlying database driver. A driver translates application API calls (e.g., JDBC, ODBC) into the Informix wire protocol (SQLI or DRDA) and vice versa. Introduction IBM Informix is a robust relational database
