A method of performing a transaction on a database. A number of transactions are available to be performed on said database. At least one of said transactions may only be performed if corresponding requirements are fulfilled, wherein the fulfillment of said requirements depends on the prior successful termination of at least one other transaction. Then, said at least one of said transactions is invoked. Depending on stored information relating to prior successful terminations of transactions it is then checked whether said corresponding requirements are fulfilled. If said requirements are fulfilled, said transaction is performed. Then, after a successful termination of said transaction, an information relating to said successful termination is stored.
