To run more clients (either networked or Web-browser based) you’ll need to purchase extra licences. Licensing is handled at the server end, so you can install the client software on as many machines on your network as you like (clients aren’t serialised), but you can only use any two of them simultaneously. Out of the box it supports two connected clients and five Web clients concurrently. The server application acts as an application server, Web server, programming design server, and client server. This has tremendous advantages in terms of redeveloping an existing database, as changes can be made away from a system that’s being used and then integrated only when all of the changes have been completed and tested. But unlike FileMaker, once you’ve created your database, all the data is stored in a separate data file. This means that, again unlike FileMaker, you can only run one database per licensed copy of the server. Unlike FileMaker, all tables for a particular database, and indeed all layouts and pieces of code, are stored within the same file. Tables are displayed graphically in a window, and you create relations by dragging links from one field to another, either within the same table or to a field in another table. Having been one of the first Mac relational databases, 4D is what you might term a ‘proper’ relational database, constructed from tables, with each table consisting of a group of fields. The server package consists of the server application, the client software, and 4D Backup, an application specifically designed for managing the backup process of shared databases.ĤD software has a very large, if mainly silent, following. Helping IT since 1993 LinksĤD Server is a cross-platform Rapid Application Development database system which lets you build databases that run on the Mac and Windows.
