Tips: ORDA Data Model Classes
By now you’re aware of the availability of ORDA classes. In this blog post, you’ll learn a few handy tips to get the most out of them!
Remote datastores – A practical use case
One of the most interesting features delivered with 4D v18 was remote datastores. They opened a whole world of possibilities and in this blog post we’ll show you a practical use case:
Multiple 4D data sources, interested?
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!
