Formation and manipulation of test data in a database system

A system to create a sandbox for an original tenant at a point in time, the system comprising:

• at least one memory, the original tenant having original tenant data stored in an immutable storage of the at least one memory associated with an original tenant identifier, the original tenant data as of the sandbox creation point in time being a virtual snapshot of the original tenant data accessible to a sandbox tenant, where sandbox tenant data can be stored in the at least one memory and can be changed or augmented without changing or augmenting the original tenant data, and the original tenant data can be changed or augmented without changing or augmenting the sandbox tenant data;
• and
• one or more servers for the original tenant and the sandbox tenant that are communicatively coupled to the at least one memory, the one or more servers to create a sandbox tenant identifier, to create the sandbox tenant by associating the sandbox tenant identifier with the virtual snapshot of the original tenant data and with data created by the sandbox tenant subsequent to the sandbox creation point in time, wherein the data created by the sandbox tenant subsequent to the sandbox creation point in time is inaccessible to the original tenant, and subsequent to the sandbox creation point in time, to create subsequent original tenant data associated with the original tenant identifier stored in the immutable storage of the at least one memory, the subsequent original tenant data not accessible to the sandbox tenant, wherein the original tenant may access tenant data created both before and after the sandbox creation point in time that is stored in the immutable storage, and wherein the subsequent original tenant data is written as new original tenant data that does not alter older original tenant data stored in the immutable storage.
