Classifications

Classifications are static lists used to populate a field/property of a table in the UI design of your app. e.g. to provide a drop down selection of product names, standard responses to questions, etc. It is probable that you will want some of the Properties (data entry boxes) in your App UI to be populated by the App User selecting from a drop-down list of options. In Evoke these are "Classifications".
Classifications are defined in the Evoke Classifications menu option and each Classification group is populated either from:
  • a Classification table in your backend database

  • via a selection from multiple tables in your backend database or

  • a fixed list that you define in your database.

On the classifications screen, that is accessed from the Evoke menu and shown on the above/right of this page, you can add new Classifcations that you will use as Entity properties. Add a new classifcation by clicking the + symbol or using "add" in the header menu; name the classification and add a free-format description. Delete one Classifcation by clicking on it to select it and then using the "delete cuirrent" menu option, delete more than one classifications by using the "Tick Select on" option, when you have "ticked" multiple classifications use the "delete ticked" menu option to delete your selected choices.
If you are using a Classifications table/file to hold your classifications then you can simply use the mandatory Classifications Entity and add records that contain the following fields 'Type' (this is the classifcation name you have used), 'Code' (Clasifiaction option for the drop down), 'info1' (will be used to set the drop down order - user numbers or letters to set the order e.g. a, b c, d...), 'description', 'info2', 'info3' are free format fields except for the classification cluture.
Video Description
The video on the right provides a detailed decription of Classifications within Evoke and should be reviewed for a detailed explaination of how to use Evoke Classifications.
Before you start with Classifications it is also important to review the startup information which contains further instructions regarding the classifications file.
Culture Classification
The Culture Classification, by default, is used to set the Data Format and Currency options for a user and is defined as follows: 'description'=currency name, 'info2'=currency symbol and 'info3'=dateformat for this user e.g. MM/DD/YYYY, DD/MM/YYYY etc. Culture is used in the AppUser Entity.
