Network

The network from a physical point of view

In the IT sector, a network is understood to be the connection of several computers in order to access data in the network together with several people. The individual components are connected either physically via cable (e.g. CAT-6 Ethernet) or wirelessly via Wi-Fi, in rare cases also via Bluetooth. If the device is located outside the physical network, in some cases the network can also be accessed via a mobile network (3G UMTS, LTE).

Connection method decides on speed

Which connection method is used determines the speed at which the network can be accessed.

wired network

Currently, the fastest and most stable connection method is the Ethernet cable connection, which is usually done at a speed of 1,000 MBit/s. Apple Macintosh computers have had an integrated Ethernet interface with 1,000 MBit/s since 2005. In order to guarantee the speed in the entire network, other network components such as routers or switches must also support a speed of 1 GBit/s. Some devices, such as printers or fax machines, only support lower speeds by default, but can usually still be used in the network without problems due to existing compatibility. Due to different standards, older 1 Gbit/s. capable devices may not be compatible with routers, switches and computers. For this reason every new configuration should be tested carefully.

Wireless networks catch up

Nowadays, WLAN networks can also offer very high speeds and, at least on paper, even offer higher bandwidth than wired networks with 1 GBit/s. In practice, however, the available bandwidth of wireless networks is usually well below the specified maximum value, because wireless networks are exposed to many interference factors. This also applies to PowerLAN networks that use the power supply system for data transmission via an adapter. Nevertheless, today’s wireless networks can in practice reach several hundred MBit/s. bandwidth, so that the speed is sufficient for most applications.

mobile networks partly very slow

The situation is different with wireless mobile networks. Due to the partly low coverage with modern transmission methods, the bandwidth in mobile radio networks can be very low. In addition, mobile radio networks are very susceptible to interference and function only partially or not at all in basement rooms, for example.

Using FileMaker in a network

FileMaker databases can be shared with FileMaker Pro (Advanced) and FileMaker Server over a local network, intranet, or the Internet.

Network sharing with FileMaker Pro

A database created with FileMaker Pro can be hosted on the network for four more, for a total of five concurrent accesses. Each client must have a licensed copy of FileMaker. Access via FileMaker Go for iOS is also possible.

FileMaker Server for professional use

If there are more than five users on the network and possibly less, a FileMaker Server for concurrent access, available for Mac OS X or Windows, is required. In addition to better performance, a FileMaker Server offers many other interesting features such as scheduled script execution, SSL encryption or scheduled runtime backups.

Enable network sharing in FileMaker Pro

To enable sharing of databases in FileMaker Pro, choose the menu command [em>[File > Sharing > Share with FileMaker clients], which displays the following dialog

Share FileMaker databases on a network

If several databases are open, you can select the file to which your change should apply under [Currently open files]. In the field [Network Sharing] you can enable or disable database sharing. In the [Network access to the file] field, specify who is allowed to access the database. If you enable the [Do not show in Startup Center] option, the databases are not displayed later when the host is selected.
