In computing, the User Programmatic Interface (UPI), also known as the User Program Interface, consists of a set of C-language software APIs which provide the lowest-level API-based interface to the Oracle database.
Overview
[edit]UPI offers a procedural API for not only performing certain database administration tasks (such as system startup and shutdown), but also for using PL/SQL or SQL to query, access, and manipulate data. The UPI library, an undocumented API used internally by Oracle, deals directly with the Two-Task Common (TTC)[1] aspect of the Oracle Client software stack.
UPI-based applications
[edit]Several Oracle database applications depend on UPI, including:
- Oracle Forms
- SQL*Plus (also uses OCI)
- Oracle Corporation's data-import and -export (IMP/EXP) utilities
UPI-Based Libraries
[edit]Several libraries depend on UPI, including:
- Oracle's FormsAPI
- The Oracle Call Interface Library
- Oracle's SQLLIB (used by Oracle's Embedded SQL Precompilers)
