RELATIONAL DATA BASE LOCK AVOIDANCE SYSTEM

The present invention is directed to a relational data base system which is operating in a virtual machine environment. The invention provides a system that includes a disconnected virtual machine which is running in the same virtual machine environment as is the relational data base. Insert and Update requests to the system are generated by programs running in user controlled virtual machines. Other users issue select and view requests which lock out insert and update requests which relate to the same data domain. With the present invention Insert and Update requests go to the disconnected virtual machine which ques them and applies them against the relational data base in the order that the requests are received. In this way, while a select is being executed on data in a particular domain of the data base, update and insert request for the same domain will be held by the virtual machine and the operator will not be "locked out" of the system.
