Many modern businesses are information- centric - their database--powered applications are key company assets. As competition mounts, your customers demand increased levels of database availability and security, including protection from downtime due to causes ranging from hardware failure to theft of a server. They recognize that the database is often a single point of failure not only of the applications, but overall productivity as well.
Not long ago, database deployments fell under one of two distinct configurations - centralized databases on one large server accessed by all users, or individual database servers with limited views of the data. While these uses served their purposes, both entailed certain limitations. A central database is a single point of failure, and remote users with low bandwidth or sporadic connections challenge the configuration. In decentralized structures, maintaining an up-to-date view of the company database for all users is an equal challenge. Collectively, these trends point to new requirements on data availability: your customers require that mission-critical data must be where users need it when they need it. And, it must be safe and secure at all times.
Pervasive DataExchange, Pervasive's database replication solution, addresses these issues. It reliably moves data between two or more Pervasive.SQL databases to maintain warm backup systems, drive data into reporting servers, or synchronize multiple remote databases. The DataExchange technology works by capturing and sharing changes from one Pervasive.SQL database to other databases in a DataExchange replication network. Each database is augmented with DataExchange, which adds two software components to a Pervasive.SQL database, the Replication Event Handler and the Replication Engine.
