We’ve got an exciting new feature to announce in 4D v18 and the title may have already given you a hint!
This feature opens new possibilities for client/server work. Rather than being limited to the current database and requiring a permanent network connection, an application in 4D v18 can get data from another, remote 4D database that’s exposed on a 4D server!
A lot of options become available thanks to this feature. For example, you could organize your applications to work offline and only synchronize local data when remote data is reachable. Or you could consider publishing your data on multiple servers and switching from one to the other as necessary. Another option could be splitting your data model across different databases (e.g. local data, international data). What about having your data distributed in different places yet still accessible through a single 4D client code (project methods and form objects)? All of these scenarios are now possible and this blog post tells you how!
There have been requests to modify the 4D Server administration dialog, with some customers wanting to remove information and others wanting to add customized information. This AdminWindow component shows you how to do just that. You can use it “as is” or modify it to fit your needs.
Today, merged applications save many information in the application package and also in the compiled file (.4DC). Besides preventing to create read-only applications, saving information in the application package has another annoying consequence: the information gets lost when you update the application.
