I am trying to set up a database to calculate and report exhaust emissions from diesel engines and am stumped at Step #1: The infamous Entity Relationship Diagram!
I am looking at a few thousand engines and need to calculate how much of what kind of pollutants they kick out into the air. I have spreadsheets that list the Year of Manufacture, the horsepower, the serial number, how long the engine ran during a given year and how much fuel it consumed during that year. I also have some spreadsheets that list what the Emission Factors, usually expressed in pounds per hour operated or pounds per gallon of fuel consumed, for each of the two dozen chemical compounds I’m interested in tracking.
Those emissions are relatively simple to calculate: Multiply the Emission Factor times the number of hours operated (or times the gallons of fuel consumed) and we’re done. Except for the fact that the Emission Factors are based on the Year of Manufacture and, in some cases, the horsepower rating of the engine, so I have to circle back around to the Engine table: I don’t know how to connect the emission factor for, say, Arsenic to a specific engine, say a 154 hp Chevy made in 2014, based on that engine’s year of manufacture and hp rating.
So my ERD keeps looking something like this: Engines --->Emission Factors--->Engines or Engines ---< Emissions >---Emission Factors--->Engines
My computer keeps puking ones and zeroes all over my keyboard when I try either setup in my Relationship Graph!
The only other way I can think of accomplishing these seemingly simple calculations is to write a boatload of scripts with variables, but I’m not even sure I could come up with all of the combinations/permutations involved. And, unfortunately, I can’ even spell SQL, let alone know how to execute one of ‘em!
I have attached a (simplified) copy of the spreadsheets I currently use to better explain my problem. I hope one of you will find this to be mind-numbingly simple and explain how it should be done. Thanks very much for your time and consideration.

I am working in a biology lab and have developed several basic databases using filemaker 11 to help the lab organise their stocks of chemicals and so on. We have a fairly onerous excel sheet that we have to fill out for registering certain new reagents we make with the regulatory authorities and as these are a pain to use, they are not filled out regularly enough. I would like to simplify this for everyone by making a filemaker form/database that will automatically fill out as much detail as possible.
The data in question is that when we clone a piece of DNA we need to insert this into several different DNA vectors that are used for different things. Whenever this one particular piece of DNA is inserted into a new vector it must be registered, so for one piece of DNA there may be , lets say 6 individual entries in the database, all saying more or less similar things, but just having different target vectors. I hope this isn’t already sounding to weird.
I have a plan that I will have a ‘home screen’ with a field for entering the name of the DNA and then some tick boxes for each of the common target vectors. What I would like is that all my colleagues will need to do is tick the boxes for the vectors they want to clone the DNA into and filemaker will then automatically populate a new entry for each of the vectors specifically for the new DNA they have cloned. As I have some basic experience, but am admittedly very limited in my scripting knowledge, I am unsure as to how best to do this. Would it be best to have a button next to each of the vectors instead of a tick box that would run a script that would take the name of the DNA in the field and then make a new entry based on the associated vector? If so can anyone suggest how this would be best organised. I am guessing I only need a single table with two layouts, one for the home screen and one for viewing all the entries.
I’m sorry if this seems a bit convoluted.
Thanks for any help.
Is there a way in AppleScript to trap if the connection is lost and have an AppleScript act on this?By ggt667
Is there a way in AppleScript to trap if the connection is lost and have an AppleScript act on this?
At the risk of asking and answering myself( AppleScript below )
repeat tell application "FileMaker Pro" try database "db" on error do shell script "sudo shutdown -r now" with administrator privileges end try end tell delay 59 -- 59 secs end repeat

A client of mine has an Windows 2008 Server which runs an SQL Server.
Because he doesn't have another machine and (Due To some reason, my client do not wish to mess with current SQL database structure),
so I will like to ins tall FM 11 runtime onto the same machine,
The runtime solution is to schedule login to SQL server to perform importing / filtering and exporting data report.
My question is :...
Has someone ever done this and can it be done?
Possible for FM to login onto same machine to access SQL DB ? Thanks!
Sorry I do not know the terminology of what I need.
I am trying to setup a database to record some info on postcodes. What I need to do is, each supplier can have 4 types of lead (back data, profile, survey, 2nd use). I have two tables for suppliers and postcodes already. I also have 2 join tables for many to many relationships. I need each field in the postcodes database to be able to store a count for each supplier's lead type.
Supplier - Lead Type - Postcode - Count
Supplier A - Back Data - AB - 20
- BB - 155
- CB - 30
Profile - AB - 55
- BB - 27
My problem is with the way I have set the relationships up currently. When I add a count for a postcode it adds that count for all suppliers. I need the postcode count to be specific to each supplier and lead type.
Can anyone tell me what I need to do to get this working correctly? I have attached a screenshot of my relationships.
