Abstract
A method enables a data manipulation action to occur between data from a data source and data in a table in a database, where the database is remote from the data source. The method includes the steps of: determining whether data from the data source comprises unique values, and if not, enabling a caching procedure. The caching procedure obtains values from the data source and transmits a query to a database management system which controls the table, including a value from the data source. A result set is received from the table, is cached, and additionally is stored for purposes of responding to the query. Thereafter, if a value from the data source is retrieved which is identical to a previously retrieved data source value, the cached corresponding result set is utilized, in lieu of transmitting a further query to the table.
