Systems and methods for use in loading data from backup databases to task databases

Abstract:

Systems and methods are provided for loading data from a database into a task database, via a stage database. One exemplary method includes accessing a backup database where the backup database includes multiple flat files and where each of the multiple flat files includes data and having a filename. The method also includes appending, by a computing device, the filename of one of the multiple flat files to an index stored in the computing device and changing a global variable associated with a data loader for the one of the multiple flat files to the filename. The method then further includes loading the data from the one of the multiple flat files into a stage database in memory of the computing device and transferring the loaded data in the stage database to a task database, thereby making the data available to queries associated with tasks relying on the loaded data.
