FM 14: Separation Model Data Mining

Note: Interface file #1 requires FM 14 or later; interface file #2 works with FM 12 or later.

What do you get when you combine the Separation Model + FM 14 placeholder text + ExecuteSQL + a million-record table + a variable array + Get(CalculationRepetitionNumber) + the Mod and Ceiling functions + a couple custom functions, with blazingly fast (local, LAN and WAN) performance thrown in for good measure?

This article w/ accompanying demo (fm-14-separated-data-mining.zip), that’s what.

The Challenge

Provide a data-mining interface to query a million-record table (cc_transactions) containing 20 years’ worth of credit card transactions. The client wants to be able to pick a date via a calendar widget, and see transaction info for that date, summarized by card type, transaction type and region.

This is a separated solution, with cc_transactions living in a file called z_data.fmp12, and a specific requirement for this project is to not make any schema changes to the data file. The data-mining will take place in a separate interface file… or in this case, two interface files, since we’re going to look at two methods.  Continue reading

Wim Decorte’s FM 12 Trigger Reference

The other day I had a question about some nuance involving script triggers. The details of that particular question aren’t important, but I recalled that when script triggers were first introduced, Wim Decorte had produced a detailed, color-coded reference.

I wondered if he had updated it for FM 12, and it turns out that he has, and with his permission I am sharing it here. There are actually two files in today’s download (Wim Decorte FM 12 Trigger Reference): the four page PDF reference, and a FM 12 file demonstrating the firing order of the various triggers.

There is a wealth of information to be gleaned from these two files, and I encourage you to download them and check them out. And of course if you find any mistakes or have any trigger-related observations to share, I hope you’ll post a comment here.

Note: even if you are sticking with FM 10 or FM 11 for the time being, if you use script triggers, the PDF in today’s download contains much that you will find relevant (hence my categorization of this post as “Version: FM 10 or later”).
