Unreferenced date December 2006 IBM Informix C ISAM also C ISAM or cisam , is an X Open standards compliant, application programming interface API to an Indexed Sequential Access Method or ISAM . Clarifyme date February 2009 Description C ISAM is an API Application Programming Interface of C Programming Language functions for managing data files organised with a B tree index scheme. C ISAM provides the underlying file storage mechanism of the Informix Standard Engine RDBMS . History C ISAM was first created by Informix in the 1980s. It provided the underlying file storage mechanism for the popular first generation Informix RDBMS Relational Database Management System , which allows data manipulation by way of the SQL Structured Query Language protocol. This version later became known as the Standard Engine SE , to distinguish it from Informix s later database engine which used RSAM. Informix initially called this the Turbo engine, but that name was later abandoned in favour of the name OnLine . Many computer systems were written using C ISAM, which was fast and efficient and flexible, while providing effective mechanisms for maintaining data integrity . C ISAM was also licensed by other software suppliers, for example as the indexed file handler in early versions of Micro Focus COBOL . C ISAM was primarily used for business applications, which were at the time often written in the C language. For business purposes, development in a low level Third generation programming language 3GL such as C could be too slow and error prone, requiring very high skill levels. Another significant limitation was in networked applications, since the use of C ISAM on a client to access a remote file system resulted in heavy network traffic. Both problems could be resolved by use of the SE to provide an SQL interface to C ISAM, using Informix s embedded SQL ESQL C and ESQL COBOL or IBM Informix 4GL 4GL products for client development. The SE could be used on a server to support networked ... more details
