The Workday is built over an object-relational database. It helps you connect to various sources like tenant SDB and Oracle. You can also export and import data in spreadsheet formats and XML.
It gives the facility to manipulate data. It uses indexes to speed up the search. You can create and maintain the queries with a robust query builder. Workday uses the data push framework to inform the users whenever there is an update quickly.
Also, since the relational database generates the reports, they are suitable for ad hoc queries and reports.
