InterSystems Cache refers to commercial object DBMS (Database Management system) from interSystems. It provides SQL and objects access to database and also allows direct manipulation of underlying data structures of cache. The cache runs on various platforms such as OpenVMS, Mac OS X, AIX, UNIX, Tru64, HP-UX, Solaris, Linux, and Windows. The old but still supported cache versions also run on SCO UnixWare and Data General AViiON.
InterSystems assert that Cache is the fastest object database in the world. However, high performance is only achieved for transactional operations that have hierarchical nature which is significant. The notable customers of InterSystems cache include hospitals that use it for running EMRs (Electronic Medical Records), and MMSs (Medicine Management Systems). Other customers include final institutions and telecommunications vendors. Independent studies have revealed that Cache is the most popular of all the object oriented database management systems.
An Intersystems Cache job can be very highly paying especially if you can who that you have experience of working with the DBMS. To get this job, you must have proper understanding of its architecture. Internally, Intersystem cache stores its data in multidimensional arrays which have the capability of carrying data that is hierarchically structured.
It is these global data structures which the MUMPs programming language uses, and which had significant influence in cache design, and they are very similar to those which MultiValue (also known as PICK) systems uses. However, in most of the applications, SQL and /or object methods of access are used. T-SQL, Cache Basic, or Cache ObjectScript can be used for the development of application business logic. The external interfaces are native object binding for .NET, ActiveX, EJB, Java, and C++. Cache also provides support for ODBC and JDBC for purpose of relational access. It also supports Web and XML services.
The technology of cache server pagers allows tag-based Web applications creation which generates Web pages dynamically, typically by the use of cache database data. InterSystems Zen is also included in cache, which is basically implementation of AJAX which enables users to develop Rich Internet Applications which are component based.
For the young persons who have passion in IT, Intersystems Cache job must be one of their dreams because it is highly paying. This is so because interSystems cache is one of the most advanced systems of database management. This DBMS has rapid environment of application development. With cache you can make great breakthroughs in the processing and analysis of complex Big Data, and the development of mobile and Web applications. Uniquely, Cache offers very fast performance, robust reliability, massive scalability, and all this comes at reduced hardware and maintenance requirements.
It is a new database generation technology which provides various data access modes. In this DBMS, data is described only once in single integrated dictionary of data, and it is instantly available by use of high-performance, object access SQL, and multidimensional access which is powerful, and all these can simultaneously access same data.
InterSystems cache comes with various scripting languages that are built in. It is compatible with some of the most popular tools of development.
