Data management system using a plurality of data operating modules

A data management method in a data management system for applying operations on data outputted from a data storage system and providing data to a processing of an application program, the data management method comprising the steps of:

• reading out requested data requested by the application program from the data storage system upon receiving a request for processing with respect to a desired data stored in the data storage system from the application program;
• selecting those data operation modules that should carry out the operations with respect to the data such that the requested data will be in compliance with a data model indicating a type of data which is suitable for the processing to be carried out by the application program wishes to carry out, from a plurality of data operation modules for operating data which have different operation functions, that are provided in advance;
• and
• applying the operations to the requested data by selected data operation modules and giving the selected data to which the operations are applied by the selected data operation modules to the application program.

A computer usable medium having computer readable program codes embodied therein for causing a computer to function as a data management system for applying operations on data outputted from a data storage system and providing data to a processing of an application program, the computer readable program codes include:

• a first computer readable program code for causing said computer to read out requested data requested by the application program from the data storage system upon receiving a request for processing with respect to a desired data stored in the data storage system from the application program;
• a second computer readable program code for causing said computer to select those data operation modules that should carry out the operations with respect to the requested data such that the requested data will be in compliance with a data model indicating a type of data which is suitable for the processing to be carried out by the application program from a plurality of data operation modules for operating data which have different operation functions, that are provided in advance;
• and
• a third computer readable program code for causing said computer to apply the operations to the requested data by selected data operation modules and giving the requested data to which the operations are applied by the selected data operation modules to the application program.
