All types of organisations as diverse as maritime, oil & gas, utilities and defence use our solutions to deliver secure and robust data frameworks, many in exacting environments.
Enables enterprises to distribute data from existing databases to remote offices and mobile workers where connectivity may be intermittent or unavailable. DataXtend RE (DXRE) enables enterprises to distribute data from existing enterprise databases to remote offices and mobile workers, providing corporate-‐level quality of service all the way to the “edge” of the enterprise where connectivity may be intermittent or unavailable. DXRE provides essential capabilities for managing distributed databases, whether your enterprise needs simple data replication or a complete synchronisation solution. With DXRE, users don’t have to be connected to a network to access data. Remote offices with limited or variable bandwidth and mobile users with limited periods of connectivity can both obtain the same quality of service levels, optimised performance and lower management costs as those in the corporate office. DXRE enables companies to manage data across multiple sites, geographies, platforms, or database management systems, through its unique patented technology for two-‐way, read-‐write replication of databases. The DXRE distributed enterprise is managed centrally but all distributed databases are synchronised transparently with the central servers. This makes deploying and supporting distributed applications as cost effective as web-‐based applications but without the network limitations associated with accessing a centralised server and database. Constructing a distributed enterprise with the DXRE eliminates traditional distributed solutions.

DataXtend RE (DXRE)
No application redesign DataXtend RE allows you to communicate with the database as you normally would, using any programming language currently in use. The result is that no application changes are needed to access the database.
And because DataXtend RE uses “update everywhere” technology, no application changes need to be made in order to update data. Minimal bandwidth utilization DataXtend RE uses a “net change” model, so only the data that has been updated since the last replication is sent through the network. Additionally, DataXtend RE technology allows you to partition data so that only the information pertinent to that site is sent through the network. Low Maintenance DataXtend RE uses “live” database access during replication sessions, so no synchronization is needed and there are no log files to manage. DataXtend RE-‐based applications can operate in a disconnected environment for extended periods with no additional maintenance requirements. Other replication solutions require extensive administrative intervention to resolve data conflicts. This is because the typical unit of replication is an entire data record. DataXtend RE technology allows administrators to partition records by update authority, allowing simultaneous updates when it complies with your business rules and avoiding false conflicts.
