Model-based analysis in a relational database

摘要

A system includes a model repository comprising a plurality of models respectively being adapted to perform, when used by an analytical program, a computational task, in which a first database table is created in the database, the first database table having a predefined table structure that corresponds to the analytical program, a best-model of the plurality of models is stored in the first database table, and a request of a client device to perform the computational task and comprising input data is received. If the received request does not comprise a model-ID, the analytical program reads the model currently stored in the first table and uses the read model for performing the computational task on the input data. If the received request comprises a model-ID, the analytical program creates a second database table having the predefined table structure in the database, reads a model associated with the model-ID from the model repository, stores the read model associated with the model-ID in the second table, and uses the model read from the second table for performing the computational task on the input data.
