General :: Data Model To Specify And Track Proficiency / Currency
Apr 13, 2014
I am looking for a data model to define and track proficiency/currency.
Example:
You earn a licence to do X. You need to renew your licence every 2 years or so. But also, to maintain currency, you need to do what the licence gives you the right to do often enough, or else you need to do a test.
Specifically, you need to do X a specified number of times N within, say, last 3 months at any one time to maintain currency. If you have lost your currency, you need to do a test/check. So at all times, you need to have N times on record within last 3 months, or a test.
In addition, to do X legally, you also need to document that you have done X at least 10 hours within, say, last 6 months, or that you have another test within those last 6 months. This is independet of the previous requirement (concerning the number of times you did X).
Both requirements must be fulfilled at all times for you to do X legally.
So, any suitable model out there? Essentially, something capable of defining and tracking currency for various ratings and license privileges of pilots would do just fine.
Hi I have designed a database for a small organization. It is a ver small database. can any one verify and tell me the mistakes in my design. It hardly takes 20 min for the people like you. This is my first step in designing. I am attaching the zip file which contains dbm file and business requirements. Complete physical data model is there.
especially in "category_tests" table i feel that i have done some thing wrong.
What's up everyone, I'm new around here and to db design as well...
I'm posting a really rough data model for the first real database I've been putting together.
I'm still in the early stages, and the concepts behind db design are still pretty foreign to me, so there are bound to be many errors I hope to iron out ASAP.
One specific question:
On all of the data models I have referenced, the "OrderDetails" table has no primary key, can someone help me to understand this? Or explain how it is wrong... Thanks
I was hoping some of the experts and advanced users around here could take a look at this and help steer me in the right direction.
I have a fairly complete data model, my question is, how best to create tables for entry where I do not have subform after subform, and subforms in subforms. With subforms for the subforms and subforms on top of that.
I am about to start pulling out some teeth because at this point it sounds fun compared to this!
Do I need to use a query to base my table off of to build my Customer entry form? Or is my only option to use 15 frikin' Subforms? I I use a query, does that cause problems with data integrity?
I am having trouble finding useful reference to this, both online and in books I have purchased.
Normalization is fantastic, I understand.... But besides the crumby Northwind sample DB that everyone and their brother directs you to, is there an actual useful sample to look over that illustrates the use of a normalized data model?
I have grown more than a bit irritated with this, mainly because of my own inablilty to make progress in putting this project together.
I would like to create a simple to use, streamlined systems that promotes efficiency and speed, not a super convoluted system that has 85 subforms on every form in the DB.
I would REALLY appreciate some feedback/direction here, I am about to give up on normalized data and go with a simple flat table approach.
I would rather have redundant data than indecipherable forms that I have to answer incessant questions about.
I have researched the 'party' data model but it is a bit too complex for what I'm seeking. For those familiar with it, I don't really need the intermediary relationship from-to tables.
I'm interested in ideas about setting up a data structure that will allow users to search contacts or select contacts in dropdowns regardless if the contact type is a person or an organization.
Obviously the fields needed for both are different and the biggest issue is the name field because the person contacts are
The way I am accomplishing it now is writing the company name, or "first name " & "last name" for a person, to kind of a bridge table when a new record is inserted into the person table or the organization table...kind of inefficient.
Is this a relationship thing or should I just write a function to create a temporary recordset when needed?
I have a table for logging experience for employees related to a given requirement.
The requirement is that any employee, to maintain proficiency ("be current") , must maintain an event count of minimum 5 within last 3 months. Or else the employee is not current and other measures must be taken.
I want to know when the currency expires for each employee (= at which date does the employee no longer have a count of minimum 5 within last 3 months).
I am writing a database to track our (and others) wine collections. i'm wanting to track what bottle is where. so i can look up what i have, look up where i have put it and away i go to get it, simple right?
just to complicate things i want a system in place. where the end user and use forms to add/remove or modify wine racks.
assuming that all racks are rectangular i would like to be able to add a rack and call it rack 1. rack 1 has 4 shelves all able to hold 5 bottles. the database would then say that bottle X is in rack 1 shelf 1 position 1.
if possible there will aslo be a screen that is auto generated by the database showing a simple grid with grrn and red squares denoting if the position if full or empty. the ability to click on a position to see what is in there or to add a bottle there would be amasing but not fussed if that can't be done.
I want a field in my table (called 'ContactTotal') that tracks the total number of times the date was changed in the field 'LastContacted' - through either table or a form, but it should exclude any changes made on the same day.
I'd also like a second field (called 'Popularity') that does the same thing, but multiplies any changes made in the last 3 months by 3, the last 3-6 months by 2, the last 12 months by 1 and anything before that by 0.
I have a form based on a query. I've disabled "Navigation Buttons" on the form and am trying to recreate their functionality in a little more user friendly way. I've created next / previous record buttons and have those working great.
I'm now trying to re-create the record counter / tracker. I'd like to setup a box that shows which record I'm on (this can simply be based on the order the query returns them, the same way the navigation buttons does it when they are enabled. ), and how many records there are total in the query.
I tried messing around a little bit with =DCount but wasn't able to make it work I suspect because I'm counting the number of records returned in a query, not in a table.
I'm trying to design a billing and invoicing database and can't seem to figure out how to link the tables and track the payments made by customers. How can I proceed to track the payments and make payments applicable to certain line items or invoices? If the line item hasn't been paid, it needs to show up on the next invoice and be included in the total due.
I have a login screen that works fine but I need to lock some part of the system from normal users but I can't figure out how to track if the user who is logged on is security level is high and can authorize the transaction!!!
I have users table and in it I record the users, passwords, security level. So when someone logs on I have no way of knowing who they are and in order check their security level. I did it in the past by setting the C drive VOL into a value and search but as we use Citrix XenApp this is not possible the C drive is the server drive and if multiple users login to to that server then the VOL value would be wrong.
We have a db to register permits that count for one calendar year. This since 2012. For next year, permits must be renewed. How can we keep track of all permits per year per user in the same table ? We would like to produce annual statistics as well ? Easy solution would have been to copy the existing table for the year 2012 and paste as a new table for year 2013 but we don't know yet who will renew his permit ...
I'm developing a database that tracks monthly metrics of employees. These employee are at several different locations.
Here's what I would like:
A table of the employees and their location.
A table of the metrics.
A form that you can select an employee and it would autofill the location and then you could fill out the metrics. the ability to change an employee's location without it effecting past records.
A report, by month and location of the employee's metrics. (pretty sure I can do this on my own, just can't get to this point.)
I've tried to use a auto lookup query but that then changes the employees location on past records.
how to change default currency in Access 2013 to a "foreign currency" (i.e. to Indonesia Rupiahs) without changing control panel (Region/Language>currency) - now setup as USA ($US)?
I have created a database that I am happy with, and I am about to receive information to populate it with. I know I am about to be asked to about security and logging of changes made to the data, which I know nothing about!!
As a result before I get into this part of my project I would like to know myself what is and what is not possible!! Currently I have 2 tables and 3 forms, one of which is a sub form........ All changes will be done via the forms, adding new records, editing existing records or even deleting obsolete records.
•Is it possible to record any changes made to the live data? oFor this to happen I presume that I need to setup users and access rights? •What type of information can be saved if any? oWhat form would this be saved in and where (a temp table?)?
While typing this a change of plan – if it is possible I am going to start building it regardless, as it will enhance my database.
I can use barcode scanning to track items through the process, on the condition that the relevant field on a form is highlighted.
The issue is I want the scanning/tracking with wireless scanners to be going on in the background while an operator can use the other functions of the database.
I'm thinking the solution is two computers, one to run the barcode scanning & tracking the other for the rest of the database functions. The problem is we only have one work PC and getting money for a new PC will be like pulling teeth.
I am just wondering if there is an advantage to using a currency field type in a table, vs. just using a number field? This is assuming that I am not working directly in the tables themselves and am using forms to display the data.
I have built a table off a form that is being used for record keeping and my question is.... This table will be constantly updated with new information so how can I make it to where when new info is added the old info will not be removed or written over?
Im working in MS Access 2003.Im creating an audit trail for users actions in a form, to monitor and keep track of what fields were updated/entered/removed from the database, these actions are essentially done from command buttons (and the audit trail, is coded on the button click)
However, I have a few search screens, that return a subform listing results. These datasheets returned are effectivly like opening the raw table and hence are editable, (permission to change is granted as they are admin only searches, yes, they can change the raw table)
How can I track the change to a raw table field, ie, if someone updates the field SURNAME from 'Smth' to 'Smith', is there something that triggers this (obviously if it was in an interface textbox, you could audit this) is their a field change. The only way i can suggest it make a recordset of the intial results, then compare that to the results in the table as they leve and compare the two.
I have a combo box to show bring up the cost of my products .Although it shows the correct prices in the combo box ,when i select the cost it posts an entirely different cost in the appropriate field. It seems to be posting the product id number with £ sign in front of it
I am re-designing a database for 2008 and trying to eliminate my Make Table Queries as I have found them to be somewhat consistant over the last year, particularily when the users do not open the database on a given date. It seems there should be a simple way to accomplish what I want but I am struggling and need some assistance.
I have attached a sample of a few tables from my database, Open Cases, Closed Cases, and Date Today. The Open and Closed tables change daily due to a Corporate download and contain several date fields which have different meanings. As new cases are opened, they go on the open table, and as an open case is closed, it moves to the closed table. The tbl_Date Today is pre-populated with dates of working days only. I have a query called "Count Of Shelf Comb" that counts the number of open cases as of today, which in truth is for all activity through the previous business day. What I want is to have a query that will show each date on the tbl_date today as well has what the total count of open cases was for that date......a permanent history of the amounts.
How can I accomplish this without using a "Make Table Query".
