摘要： A method, apparatus, and article of manufacture for a computer implemented authorization system. A statement is to be executed by a computer to manipulate data in a database stored on a data storage device connected to the computer. Initially, an environment of the database from which the statement was invoked is identified. Additionally, a security option is identified. Then, authorization privileges for the statement are determined based on the identified environment and security option.

摘要： A system, method, and computer program product for establishing mutual trust on a per-deployment basis between two software modules. For example, the first software module may be a Websphere (WS) Information Integrator (II) deployment instance, and the second software module may be a plugin instance. By executing for this deployment an initial handshake between the software modules, both modules identify themselves and exchange digital certificates received from a trusted certification authority and respective public keys. Subsequent communications for this deployment between the software modules proceed with each module encrypting its communications with the public key of the other module; thereby establishing mutual trust between the software modules for each deployment.

摘要： A technique for optimizing execution of a query that accesses data stored on a data store connected to a computer. Query predicates involving different data types are identified. A second query predicate is generated which includes matching data types, and if necessary, converted operators. The second query predicate with the matching data types and/or converted operators is executed to obtain a subset of records using an index manager or data manager. The subset of records is converted to the data types of the remaining query predicates. The first query predicate is applied against the subset of records to obtain a result, and the remaining query predicates of the original query are applied to the result of the first query predicate and any other additional converted query predicates to obtain a final result.
