How to connect to a remote server
BaseNow can connect to the databases that are located on a local computer,
i.e. on the same computer where BaseNow is installed. Also, the program
can connect to the databases, such as SQL Server, Oracle, and the like,
which may be located on some other continent and to which the connection
is established over the Internet. Data are transmitted over the network,
either local or the Internet, in most cases using TCP/IP protocol.
The program has been optimized to work with remote servers over the
Internet connection or LAN. The network is often slow and data transmission
can result in traffic congestion. When the Local
Cursor option of the program is used, BaseNow does not connect to
a remote server every time a record is to be displayed or it is necessary
to move from one record to another. Instead, the program performs all
the operations on a copy of the table or the database on the local hard
disk. When a connection is established, the relevant data are transmitted
to the local computer. Consequently, their processing is accelerated and
the database server off-loaded. You can expect a delay while the program
caches data on the local computer.
In a situation when many clients who do not use local cursor are connected
to the database server at the same time, working with data becomes considerably
slower and the data from the server can even become unavailable.
The example on the video shows how a connection with an SQL Server located
on the Internet is created. Its IP address, database name, username and
password are entered in the Data
Link Properties window. Today, a number of web hosting companies which
have Windows NT/2000 servers offer the SQL Server option which allows
you to have your data available on the Internet 24 hours a day. BaseNow
makes the data manipulation and database structure modification much easier
for you.
