Abstract
A Client/Server Database system is described which includes a Database Server providing methods for executing system-created internal command statements (e.g., SQL statements), such as those which ordinarily are submitted to the server by various Clients. The Database Server is modified so that it can be its own "user," thus removing the fundamental schism which had existed in prior systems. The system is allowed to issue SQL commands to itself and, thus, can do anything that either the system or the user can do. The methodology is particularly useful for carrying out upgrades. The system can now set flags that are not accessible to users. Unlike a standalone "utility" approach, however, authentication is assured. Here, the system is assured that a known user--itself--has issued the command. As a result, it is no longer necessary to expose "dangerous" system functions to users.
