DATABASES in DECT Messenger

This section describes the databases used by DECT Messenger.

Supported Database types

DECT Messenger uses two databases:

• Configuration Database

In this database, all configuration data is stored. You can make a copy of this database

as a configuration backup. This database is always an MS Access type, and has file name:

Messenger_CFG.mdb.

• Dynamic Database

The dynamic database contains all data about messages. There are three types of

databases possible:

- MS Access

This is a simple solution that does not require extra database setup actions. The

disadvantage of the MS-Access type of database is that the database slowly grows,

eventually consuming significant resources. After you shut down the eKERNEL, a

database compression function runs to reduce the size of the database.

The database has the file name: Messenger_DATA.mdb.

The DECT Messenger eKERNEL has direct access to the database. The eWEB module

has access to the database through ODBC.

- MSDE

The MSDE (MicroSoft Database Engine) is the database engine that is used in the

MS SQL database. However, no user interface is available, and the maximum

number of concurrent users is five. This is not a problem for DECT Messenger

because you do not need database maintenance on the DECT Messenger database.

To install the database under MSDE, a Batch file is available. The number of

concurrent users is normally less than five.

The DECT Messenger eKERNEL and the eWEB modules have access to the

database through ODBC. You must set up the ODBC link in the ODBC, which is

described in Installing ODBC.

- SQL Server
