FLAP and Fileman's Architectural Role

To say that File Manager is VISTA's database management system is a gross understatement, so gross that it is more misleading than helpful.

Traditional database systems run side by side with the applications, offering data-related services (like creating, reading, updating, and deleting records - the services with the unattractive acronym CRUD - along with many, many other such services). In other words, most DBMSes have a peer-to-peer relationship with the applications that use them to manage their data.

FLAP and Fileman Code Convergence

One of the two top strategic goals for FLAP Phase One (which ran from October 2012 through March 2013) was code convergence, to create a shared, common Fileman codebase that all VISTA dialects could run, to maximize our ability to exchange data and software with one another, to ensure that innovations anywhere became innovations everywhere as quickly as possible, and to reduce the amount of reinventing the wheel we had to do.

The main VISTA dialects we aimed at converging for Phase One were:

1) VA VISTA

2) IHS RPMS

3) WorldVistA EHR

4) vxVistA, and

FLAP Phase Two Preparation Has Begun

FLAP Phase Two began yesterday - Sunday, 23 November 2014 - with the launching of a Preparatory stage.

Database Elements Problem 1: Standard or Local Data

So then which aspects of what VISTA is made of make this more complex than it seems?
 
Many things. Let's start with the data.
 
In some files, such as the State file (#5), the contents are shared. It's not like the number of U.S. states changes depending on whether your VISTA system is running at a VA hospital in Tampa, Florida or Cheyenne, Wyoming. This file is not yet optimized for use by other nations, so at present it's pretty much just a description of U.S. states, which means its contents should be the same for all VISTA systems.

Non-routine Software Elements Part 1: Data and Definitions

Yes, but what is VISTA made of?
 
So at the MUMPS level, VISTA is made of two kinds of software elements, routines and globals. Routines are readily version-controlled and managed (in theory) using industry-standard tools, but globals are not. Globals need to be flattened and exported in some way that focuses on the database files we are storing in those globals.
 
As we're going to see, this second "half" of the problem (globals, as opposed to routines) is really a lot more than half the problem.

Vista EHR Class at SUNY Albany - Spring 2014 - Teaching FileMan

As part of the VistA EHR Class at SUNY Albany,
we covered recently the topic of FileMan.

To this end, we used the following materials

JSON-LD as FileMan's Data Format

In its 1.1 release, FMQL will move its JSON format over to JSON-LD. This form of JSON provides a straightforward JSON with rigorous semantics, something key for VistA data with its large and powerful data model.

Fileman Tutorial for New Programmers...

I am please to announce that I finished writing a Fileman tutorial for programming students that I promised Luis Ibañez. Here it is.

Thank you Luis for the impetus, and sorry it took so long.

Fileman 22.2 Getting Started Manual: UPDATE

We got more reader feedback (thank you!), so here is an updated version of the Getting Started Manual. Hopefully this is also the final version.

We are now working on the Security Manual, and hope to have it available by the end of February.

Certification Working Group Meeting Notes From February 2, 2013

We will use the new peer review checklist to walk through peer review for FileMan 22.2 in the OTJ. Peer review checklist is at:

Update: We had a very successful consensus review of Fileman 22.2 during yesterday's meeting. Based on the meeting, we have the following two actions that need to be investigated, after which we will submit a recommendation via the peer review:
