186 Part 5: Databases 3 Performing a replication The replication is used to keep the remote databases of identical structure updated. A replication can be performed between the database of a WEBDEV site and the database of a WINDEV application at the company headquarters. For example, a database used to enter orders and to manage stocks is used both on aWEBDEV site (online orders) and at the company headquarters (orders by phone or by mail). The replication is used to: • transmit the online orders to the company headquarters (unidirectional replication). • transmit the online orders to the company headquarters and transmit the stock update to the Internet site (bi-directional replication). Caution : The replication constraints must be taken into account during the project creation. Indeed, several rules must be followed when describing the analysis and the file items. The replication can be performed by email or via the assisted universal replication. For more details on replications, see the online help.
