Adding Reliability to Occasionally Connected Computing in Mobile Devices

Mobile devices use wireless networks that have limited range. Therefore, they may not always be connected to a network. This kind of intermittent connectivity in mobile devices has been one of the factors inhibiting enterprise-level adoption of pervasive mobile applications. Occasionally Connected Computing (OCC) deals with this problem. The challenge that mobile application developers f... (more)

Enabling Offline SOA Using SDO and ADO.NET

Enterprises frequently have to deal with part of their infrastructure that doesn't have the privilege of uninterrupted connectivity.
