Method relating to databases

A method of handling the risk of a deadlock between simultaneous transactions in a database, in which respective objects in said database are allocated at least one lockout queue in which transactions that have requested access to an object are placed and there await the access of a preceding transaction to said object, and in which said handling procedure includes perusing the transactions present in said lockout queues, comprising the steps of providing that a transaction active or ongoing in said database can be categorised as a locking transaction, that a locking transaction can cause a deadlock in combination with one or more other transactions, that combinations of a locking transaction and one or more other transactions are categorised as locking combinations and non-locking combinations respectively, that a non-locking combination never results in a deadlock, that a locking combination can result in a deadlock, that the detection of a locking transaction results in a further perusal of said locking queues, that in said further perusal said locking transaction is compared with transactions that are affiliated to said lockout queues in order to establish whether or not said combination of transactions constitutes a locking or a non-locking combination, and in that solely the detection of a locking combination results in further action.
