Open Database Connectivity (ODBC) is a standard application programming interface (API) that enables applications to access data from various database management systems (DBMS), such as Microsoft SQL Server, MySQL, PostgreSQL, or Oracle. On Windows 7, ODBC drivers act as translators between a specific database and an application (e.g., Microsoft Excel, Access, or custom software). Proper installation and configuration of these drivers are essential for data integration, reporting, and legacy system support. | Symptom | Likely Cause | Solution |
