Table 2-2 Oracle-Provided DBCA Templates and Their Corresponding Workloads

Template Workload

Template	Workload
Data warehouse	Users perform numerous, complex queries that process large volumes of data. Response time, accuracy, and availability are key issues. These queries (`SELECT` statements) range from a fetch of a few records to queries that sort thousands of records from many different tables.
General Purpose or Transaction processing	Many concurrent users perform numerous transactions that require rapid access to data. Availability, speed, concurrency, and recoverability are key issues. Transactions consist of reading (`SELECT` statements), writing (`INSERT` and `UPDATE` statements), and deleting (`DELETE` statements) data in database tables.
Custom database	This template allows you maximum flexibility in defining a database because you can change any of the settings for the database being created.
