Abstract: An exemplary database management device includes a database storage memory for storing database information. A user access memory at least temporarily stores information to be included in the database. At least a portion of the user access memory is configured to operate as a database manager that allows a user to indicate an intended change to the database information. The database manager places the intended change into the user access memory and determines whether the intended change complies with a criterion responsive to the user attempting to implement the intended change. The database manager makes the intended change to the database information in the database storage memory if the intended change complies with the criterion. The database manager provides an indication that the intended change will not be made to the database and the database storage memory if the intended change does not comply with the criterion.
