If you start the client for the first time, you will not be connected to any database, indicated by the icon in the left upper corner as shown below.
If you are not connected to a database
this will be indicated by the
icon 
of the connection button. If you are connected to a database this is indicated by
the icon
. To access any database, you
must specify the server where the database is located. For the configuration of
this connection choose Connection, Database...
from the menu or click on the button.
A dialog will open, where you can specify the name or IP-adress and port number of the server and the authentication mode. You can either choose Windows authentication (see left image below) or SQL-Server authentication (see middle image below).
The standard port number for SQL-Server is 1433 and
will be set as a default. If the database server is
configured using a port different from that port, you must give the
port number in the field Port. Click on the
button to connect to the server. If the
connection informations are valid, you can choose a database from the server
from the combobox at the base of the form (see right image above). To restart the connecting process click
on the
button.
If you access a database for the first time you will be asked to consent to the storage and processing of your personal data (see below) according to the General Data Protection Regulation. Without your consent the access is not possible.
