The informixdb package (not actively maintained) or using ODBC via pyodbc . Modern approach: ifxPy (IBM’s Python driver – part of CSDK). informix driver

Lowest latency, direct access to database features (e.g., collections, row types). Cons: C-only, less portable, manual memory management. 3.2 ODBC Driver Standard: ODBC 3.8 compliant Connection String Example: import ifxPy conn = ifxPy

Informix, database driver, ODBC, JDBC, CSDK, connectivity, performance tuning, transaction isolation 1. 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. Cons: C-only, less portable, manual memory management
