Access 2007 Methods: Structure of tables/forms for entering data
Posted on 2011-02-18
Good morning, I am going to be building a new database and I would like to get some feedback from more knowledable Access experts before I begin. The database will likely consist of many forms/tables and will serve as a template for projects where students or other users will abstract information from academic literature (to create a database of information for writing up reports). The goal will be to capture all relevant information contained in the article, but because this is a template it can not be specifically tailored to a single project.
Some of the forms will gather routine information that is conserved across projects (for example Authors, Title, Journal, number of participants, number lost to follow up) but because of the varying study designs one article might have 3 study groups whereas another could have 1 (ie. an observational study with 3 group vs. a randomized trial with a control and two experimental groups) or include multiple diseases etc... My first question is this, how do you suggest implementing form/table structure to deal with this disparate 'length' of data in each study? Do I make a single table for, for example study characteristics and have Group1, Group2, Group3 .... Group7 fields and so on for each of these items that could contain multiple entries? And how should this be presented on the form so that data entry is elegant and not an exercise in navigating through many fields which could be irrelevant to a specific study? One method I thought of was to hide many of the form controls and have them appear on some selection (i.e. a radio button or combo box for number of groups) but this might still be a bit messy. Does anyone have any ideas about how to make the form controls dynamic to what the user needs to transcribe? Another issue to keep in mind will be that the data for these entires will be cross checked with another student/user's entry so I will likely be adding multiple list boxes for users to make selections where 'open ended' text entry isn't necessary (for example in selecting study type or disease which are fairly consistent).
Anyone's help will be greatly appreciated and I will gladly answer any additional questions you might have.
Thanks in advance for any help,
