InterSystems Caché is an object database management system from InterSystems Corporation. It provides object and SQL access to the database, as well as allowing direct manipulation of Caché’s underlying data structures. The company claims Caché is the world’s fastest database [1]. Caché runs on Windows, Linux, Sun Solaris, HP-UX, Tru64 UNIX, AIX, Mac OS X and OpenVMS platforms (old, still supported versions of Caché, also run on Data General Aviion and SCO UnixWare).
Notable customers of this DBMS are many US hospitals, who run their Electronic Medical Record systems using Caché, financial institutions like Ameritrade and Sungard, and others including IBM, BT, and Vodacom.
Architecture
Internally, Caché stores data in multidimensional arrays capable of carrying hierarchically structured data. These are the same “global” data structures used by the MUMPS database language, and are similar to those used by MultiValue (aka PICK) systems. In most applications, however, object and/or SQL access methods are used.
Caché ObjectScript, Caché Basic or T-SQL can be used to develop application business logic. External interfaces include native object binding for C++, Java, EJB, ActiveX, and .NET. Caché supports JDBC and ODBC for relational access. XML and Web Services are also supported.
Caché Server Pages technology allows tag-based creation of Web applications that dynamically generate Web pages, typically using data from a Caché database. Caché also includes InterSystems Zen, an implementation of AJAX that enables component-based development of Rich Internet Applications.
Competitors
The main competitors are vendors of relational databases such as DB2 from IBM, MS-SQL from Microsoft, MySQL and Oracle.
