ABSTRACT:
A method for ensuring reliable interactions between principals within a database or between databases. The method involves the creation of database contracts which are, in essence, binding constraints on the behavior of entities within a database system that can be enforced by the system. A database contract is formed when two or more principals agree on the terms and conditions of the contract, and a monitor puts in to place the constraints necessary to enforce the agreed-upon terms and conditions after determining that each of the principals has the requisite authority and ability to carry out the contract.
