Custom-built SQLData Server
If you have specific needs in your database services, such as custom
encryption/decryption algorithm, application specific data validation, or business related
transaction control. We can build special edition to meet your requirements. For the
Dynamic Server Groups (DSG), we offers the following choices:
 | Dedicated Group Controller: A server that is responsible for group coordination and
management. The Group Controller may also be used for designating primary servers and
backup servers within the group. |
| Database Proxy: This is special server that performs security checking and session
management. All database requests are dispatched to other hosts. The server is used for
enhancing server security (customer never directly interacts with database servers) and
for better load balancing (The proxy server has all information needed for distributing
requests evenly). |
| Backup Server: Any of the SQLData server can serve as a backup server to one of the host
in the environment (one to one backup). If you need to have a backup server that supports
multiple primary servers, we would be glad to build a special version for you. |
