Hello,

I am thinking on how FM7 new function benefit if I want to design a new FM7 solution with Data & Interface separation method.

For FM6, the reason I like data & interface separation method is easy for future development after implement. I also make the portal (in interface file) as list view and I can limit what user can see, to improve security. But I also hate this method because it made many FM default functions like find, sort... requires developer to use script and calculation fields to make similar functions.

I would like to hear all of you sharing experiences and comments on "Data & Interface separation method", especially if you have convert or re-write the solution by this method.

Thanks,

Damon

If you haven't read the Separation Model in Migration Foundations and Methodologies take the time to read it.

I have converted a set of files using that a guide. I did most of it from scratch. I did copy some layouts. And I was able to transfer the data. I ended up with 3 files: (1) Interface, (2) Business Rules & Reports and (3) Data.

I am pleased with the outcome.

hi, ralphl , where can i get this "Separation Model in Migration Foundations and Methodologies" doc ?

regards,

Could you tell us more about business rules and how the whole thing is tied together - or separated?

Here's the document: http://www.filemaker.com/downloads/pdf/techbrief_fm7_foundations.pdf

The article on the "Separation Model" is on page 112ff.

The business rules are the calculations necessary for the business. In general there is a table for every data table. A One To One relationship exists between the data table and the business rule table. You may have some additional tables for reports. This means that when you create a new record in a data table you must also create one in the business rules table.

thanks , detlev ! i got it.

Thanks RalphL, I will have a look of your suggested doc.

Damon

could you provide a link to a set of simple example file that has the interface, business and data files all separated. I am curious about how you separated the business logic from interface and data files.

thanks
