Truncating data associated with objects in a multi-tenant database

A computer-implemented method of removing stored data associated with a database object, the method comprising:

• assigning a new and previously unused key prefix to an existing database object to disassociate stored data from an old key prefix, resulting in an empty database object that is void of data;
• updating a graphical representation of a table to reflect the empty database object and
• presenting the graphical representation of the table to a user, wherein:
• the existing database object includes a first entry that is linked to a foreign key maintained in a second entry of a target database object, the foreign key stored in a field identified by a first column number;
• and
• the method further comprises altering metadata for the second entry of the target database object by replacing the first column number with a new and previously unused column number, in response to assigning the new and previously unused key prefix to the existing database object.

• presenting the graphical representation of the table to a user, wherein:
• the existing database object includes a first entry that is linked to a summary field value maintained in a second entry of a target database object;
• and
• the method further comprises updating the summary field value in response to assigning the new and previously unused key prefix to the existing database object.

A computer-implemented method of removing stored data associated with a database object, the method comprising:

• maintaining a custom entity definition table having a metadata entry corresponding to an existing database object;
• assigning a new and previously unused key prefix to the existing database object to disassociate stored data from an old key prefix, resulting in an empty database object that is void of data;
• updating a graphical representation of a table to reflect the empty database object;
• and
• presenting the graphical representation of the table to a user, wherein:
• the metadata entry includes the old key prefix in a key prefix field;
• and
• assigning the new and previously unused key prefix comprises updating the metadata entry to include the new and previously unused key prefix in the key prefix field, to obtain an updated metadata entry that corresponds to the updated database object.
