Abstract: The invention is in the area of distributed system and database security. The invention relates to a method and an arrangement for increasing the level of trust between a master and a replica database by allowing the master database to perform an “unpredictable” audit of the replica database whenever deemed appropriate by the master database. The master database may for example define and generate an audit application and send it to at least one replica database using push synchronization and force the replica database to perform the audit application. The master database may also prepare expected results of the audit of the replica database and store them for later verification. After auditing the replica database may synchronize the results of the audit back to the master database for verification. The information flow between the master and replica databases is advantageously encrypted in a secure manner.

Abstract: The invention relates generally to the management of distributed databases, and more particularly to a method and an arrangement associated with managing database schemas and configuration of software that uses those schemas. The objective of this invention is to present a method and a system, which allows managing database schemas and application software in large distributed multi-database systems and avoiding problems that are related to the prior art systems. The objective of the invention is attained by using configuration manager apparatus (231), which is external to the configuration and databases being managed (200). The objective of the invention is preferably also attained by providing a mechanism for keeping multiple, possibly different database schemas and application software in synchronization. The external configuration management node (231) manages the configuration management replicas (203, 213, 223) in each part (201, 211, 221) of the distributed database system (200).

Abstract: The invention relates generally to the use of databases. Preferably the invention relates to a method and a system associated with the use of databases with mobile terminals (220). The objective of this invention is to present a method and a system which allows managing a large dynamically changeable set of applications in the mobile Internet. The objectives of the invention are attained by determining user profiles within communities, and the rights for using applications of a community server (201) depends on the profiles of the user within the community. The identity information is preferably maintained in an identity server (202). The invention provides a solution to the problem of managing services and configuration of smart network node in environments where the services and their content data need to be managed remotely from multiple remote sources in a dynamic manner.

Abstract: A plurality of steps, which are intended to modify the data in a transaction, form a transaction (40) comprising statements (41, 42, 43). In the method according to the invention there is formed a data exchange space (47) common to the transaction in order to make the parameters available to the statements belonging to the transaction and in order to transmit data between the statements belonging to the transaction. The system (30) maintaining the first version of the database is arranged to store the modifications to be made in the database as transactions, which comprise statements as well as parameters, both regarding the statements and regarding the transaction.
