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.
