Funzionalità 4D aggiuntive

Client Expansion

The number of Client Expansion licenses determine the number of devices that can connect at the same time to the 4D Server. These licenses are to be installed on the 4D Server. Purchase additional Client Expansions to add as many additional concurrent users when needed.

Used with 4D Server applications, client applications can be installed on macOS, Windows machines, and/or iOS devices.

4D Web Application

If you want to create a 4D Web application, this product is perfect for you. Aside from its flexibility and extensive built-in capabilities, the 4D web application allows unlimited access to the integrated HTTP server of your business application. It can be assigned to either the 4D server or the remote application (Client license). This will allow you to publish your Web server on a dedicated machine, such as a data center or provider, or multiple web applications that are associated with the same database.

4D Web Services

Web services can be consumed or published. In 4D, consuming Web Services is a standard feature. With this additional license, you can also publish web services with just one click, either in DOC or RPC (remote procedure call) style. In addition, you get programmable and controllable security features, as well as, an automatic WSDL (Web Services Definition Language) publication.

With a high degree of flexibility, it can be assigned to either the 4D server or the remote application (Client license).


External data access

If you want to access external data sources, 4D provides two solutions. ODBC (Open Database Connectivity Standard) in case you need to communicate with any ODBC client that’s accessible via the ODBC driver, and thus manipulate the data and structure of a SQL data source. 4D for OCI allows your 4D database to communicate with an Oracle database. This means your 4D database can display, manipulate, and modify data that is stored in an Oracle database.
