Design Question. It works now...but how to redesign it?
Yet again, I'm in way over my head! I'm going to simplify the current
situation to make it easy to understand (and communicate), and hopefully I will be able to do what I intend to do without crashing everything that I currently have! I have a training management database. It pretty much automates my position for the guy taking my place. I have it set up to tie various training requirements to the positions in the unit. The problem: Lets say someone gets promoted. They move positions. As a result, all of the completed training (tied to the position itself) must be reset to zero and reentered. In the event that they then move on to ANOTHER position where some of the previous training now counts again, I have lost all record of that original training that they did in their first position. My solution: Tie the training REQUIRED to the position. Then tie the COMPLETION DATA to the individual! Currently: 1. Table of personnel data. Unfortunately, being a military unit, SSN is the PK. This table assigns a person to a position. 2. Table of Training. This ties the individual courses to the position. Training ID is the PK. This includes the fields for 'Enrolled' and 'Completed.' 3. Tables are joined by relationships - one-to-many from the personnel data Position field to the training Position field. This works outstanding! Aside from having to reinvent the wheel every time a person moves! (which happens more often than you'd think) My Goal: 1. Table of Personnel Data. This still assigns the person to a position. PK is still SSN. We'll call this table 'PD.' 2. Table of Required Training. This is designed the same as above, minus the 'enrolled' and 'completed' fields. PK is Training ID. We'll call this table 'RD.' (Note: My relationship - one-to-many from PDPosition and RTPosition works great to generate what training is required for each position!) 3. Table of Completed Training. This table will include all of the training that an individual has completed throughout their lifetime on the team. Not all training will be required for all positions, but I don't want to lose the history of what they have accomplished. But this table is my nemesis!!! PK is Training ID (no relation to Table of Required Training's Training ID field). We'll call this table 'CT.' While I got the Query between tables 1 and 2 to work great, I need this monstrosity to do the following: Identify the position that a person is assigned to. Pull the required training for that position. Then, pull the completed and enrolled data for ONLY the courses that are required for the position. In short, a query design would look something like this: (which doesn't work! It pulls all of the training, regardless of position, and assigns it to the person) PD-SSN...PD-Position...RT-Course Title...CT-Enrolled...CT-Completed. What I can't make it do: Ignore the extra training that a person has done that is also in the CT table! Thanks in advance. Kim |

If I'm understanding your description, you want the completed training information to follow the person AND their role/position, not just the person. That would imply that you need to show Completed Training with: TrainingID PersonID RoleID ... and other completed-training-related info Are you doing this now?

Some suggestions --
1. Personel data - information that NEVER changes - MemberID Autonumber primary key, SSN, DOB, Gender, FName, Middle, LName, Remarks (If by chance LName changed) 2. Assignment - AsgID Autonumber primary key, MemberID long interger foreign key, MOS, Rank, Position long interger foreign key, AsgDate, XferDate, etc. 3. Position - PosID Autonumber primary key, Title, etc. 4. Training - TrainID Autonumber primary key, Title, Level, Recur long integer, Period (M- month, Q- quarter, YYYY- year, W- week), Slip 'S' or 'C' (next required from last scheduled or last completed) 5. PositionTng - PosID long interger foreign key, TrainID long interger foreign key 6. TngHistory - TngHisID Autonumber primary key, MemberID long interger foreign key, TrainID long interger foreign key, ReqDate DateTime, CompDate DateTime, Query to create TngHistory record -- MemberID, TrainID, XferDate null, ReqDate = IIF(Max([ReqDate]) Is Null, Date(), DateAdd([Period], [Recur], IIF([Slip] = "S", Max([ReqDate]), Max([CompDate])) ) Max([ReqDate]) based on having past record for individual for this TrainID. If not past record then Date() as ReqDate. -- Build a little, test a little. "Kimberly3626" wrote: Yet again, I'm in way over my head!

Sounds like you have quite a situation.
Here is the best solution that I can come up with, from what I understand of your situation. You obviously need an Person table of some sort. You need a MOS table You need a Training table and a linkage table between MOS and Training, because you are likely to have multiple MOS's need the same training. And just to throw a monkey wrench into the whole thing, you have some training programs that apply not only to multiple MOS's, but may also apply to multiple ranks. My experience, when I was in the military, was that typically you couldn't get promoted until you fulfilled all the previous requirements. But I wasn't closely involved with the the Personal Actions office. I would hate for your linkage table to end up needing the same MOS and the only difference in the record is a rank attribute, but there shouldn't be any reason to have a rank table. You could possibly use a multi-valued field to store the rank(s).

Design Question. It works now...but how to redesign it?
Sorry for the delay...got stuck on a short notice trip!
First, I have really good news! I'm actually tracking training that is position-specific and is completely independant of the rank and/or MOS of the individual! We have some positions that are non-MOS specific...(As for the Rank/MOS training, I can do that manually because we don't have many switches between MOSs or Enlisted officer. As a result, I just load all of the required training for your lifetime in one shot and check it off as you complete it) One example of what I'm dealing with: Me! I was in Position A, which required Course A, Course B, and Course C. I moved into Position B. This position requires Course A, Course C, and Course D. With the training tied to the position, the way it is now, when I move into Position B, I have to not only clear the training data for the person who was there before me, but I also have to enter all of my data from scratch. In addition, I lose the database proof that I completed Course B. This is only a problem because if we are certified in one position, we can cover it on our own team or on another across the country. Without being able to pull the certified personnel out of the DB, I lose the ability to cross-assign people to meet a nationwide mission. Seemingly not hard with the above example of 4 courses, but in reality, I manage over 24,000 hours of training for the team that is completely position dependant! Looking at the replies, it seems like Karl's idea might work the best, minus the Training Table (I'll only use the position training table for now). I'll see what I can get to work, and let you all know what pops up... If there are any more ideas that will work with the new 'simplified' requirements, I'd love to hear em too! Not having the MOS wrench is a huge help to the situation. Thanks again! |
