Opportunities, Which Sybase Database Replication Can Give You
Sybase database replication server remains reliable and steady mechanism for construction of systems meeting the real business requirements. Sybase Database Replication Server falls outside the limits of the distributed databases and gives the first decision for construction of the present distributed systems - flexible architecture for construction of systems meeting the real business requirements. Earlier architecture of the distributed databases use the report of biphasic end of transactions (2PC), which is too expensive for a daily use and can lead to block system because of the denial of one of the components.
In other approaches the simplified mechanism of "instant pictures" tables (snapshots) is used, which does not use transaction and consequently does not provide transaction integrity of data spears. Offering real decisions for real problems, Replication Server is leader among the products for replication.
Replication Server synchronizes data copies, which are on heterogeneous platforms in the client-server network. It provides the highest productivity at operative processing of transactions, eliminating the basic contradiction between productivity of appendices OLTP (On-Line Transactions Processing) and Decision Support Systems.
It also provides a high degree of local autonomy and flexibility. Data can update the removed places, using the safe mechanism of updating. Transforming the information hurriedly, Replication Server synchronizes databases with different structures, formats of data and names of fields and tables. The flexible mechanism of replication provides notification of the removed places, allowing each removed place to react to the events according to the local necessities.
Replication Server supports failure-safe work of system - architecture of appendices, which allows users to continue work even in cases of absence of communication with the separate parts of the distributed system. After restoration of communication Replication Server automatically synchronizes databases. Replication Server is a key component in development of the effective distributed systems meeting the major requirements of business. It solves some major problems of clients, not solved by means of usual architecture of the distributed databases, such as corporate association, decentralization, high availability and Decision Support Systems.
Replication Server allows you to place data in those places where these data are necessary. It reduces a dependence on refusals of the central computer and networks of data transmission and cuts down the general expenses on the information interchange. It also supports bi-directional data sharing using a safe way of updating of the removed data. The systems using Replication Server remain reliable and steady, despite of failures of the equipment, the software and networks. Such systems provide very high time of reaction at reasonable expenses.
