    Default Runtime Vs Shadow system

    I am new to Alpha 5 V9. I intend to install alpha5 on the staff computers so that they can view only reports and browse from a master file on a server at headquarters. The staff members wont be able to up date the master file. Should I use runtime or shadow system

    Can someone please help.

    Thanks

    This is not an or question.

    You should use the runtime.

    The shadowing of a runtime installation reduces the time spent loading layouts from the server for use by a workstation. It is possible to design a system where the benefits of shadowing are negligible.
    There can be only one.

    To supplement what Stan said, let me add:

    a) "runtime" has to do with which version of Alpha Five is deployed to the client work stations. Both the "runtime" and the "Full" or "Developer" versions can edit data across a network. To suppress edits you must design the forms that the end user will be using so that edits are blocked.

    b) "shadow" has to do with how the local work station interacts with the server. You can run a "shadowed" database with either the full or runtime versions.

    As Stan says (in fewer words) "runtime" and "shadow" are not alternatives to each other. They are different things altogether.
