What is Stored in the aPriori Database?

To understand how data stored in the aPriori database can be segregated, you must first understand how that data is stored.

There are three types of data stored in the aPriori operational database:

• License Data – The license data for aPriori resides on the database. Each aPriori license specifies the number of named users that are allowed to log into the database, and aPriori licensing is named-user licensing. When a user attempts to log into the aPriori client, the user details that are provided are validated against the list of valid users that is stored in the database. If the user details match a user in the database, then that user is logged in.

As the aPriori license resides on the database, this means that a user can log in from any PC that the aPriori client is installed on.

• Virtual Production Environment (VPE) data – A VPE contains the algorithms and rates that are used to calculate the cost of a scenario. As the VPE is stored in the database, this means that all users can always use the most up to date algorithms and data

• Component data – Whenever a scenario is costed in aPriori, the results are saved to the database. This allows different users to share results and perform analysis on a wide range of scenarios from around their company.

When aPriori is first installed, the three types of data reside within the same database schema, which is the schema specified in the local file hibernate.properties. This is the Master Database Connection.
