A field is a container for a certain data class. There are four classes of Fields:
•Record Attribute Fields,
•Index Fields,
•Attribute Fields; and
•Sub-attribute Fields.
Their relation to each other is discussed in the Data Structure section of this document.
The fields are used to define a record. Assigned access rights limit the fields on which a specific user may work. The Autshumato TMS, by default, has predefined fields already present.
Fields are also defined by their type and can be one of the following:
•Text
Can contain text data, which includes numbers, text, links and formulas. This is a generic field in which almost any type of data can be entered.
•Pre-set
The pre-set field type has certain defined pre-set values. These fields may only have values that are predefined for the field. All pre-set fields automatically have the ‘None’ pre-set for when the field does not contain any data. Only Attribute and Sub-attribute fields may be of the pre-set type.
•Synonym
A synonym field type is a field that is a synonym of the Index field under which this field falls. Only Attribute fields may be of the type Synonym.
Furthermore, fields are defined by their data type. A field can have one of the following data types:
•Plain Text
A field with the plain text data type contains plain text.
•Integer
Integer fields can only contain integer numbers.
•Floating-point number
Floating point fields can only contain floating point numbers.
•HTML Hyperlink
The HTML Hyperlink field data type is used for Images and Sounds. When a field is defined with this data type, you will not be able to enter any data into the field. When this field is selected during editing, an upload dialog will be displayed. If the user uploads either an image or sound, it will be available on this field of the record when it is rendered.
•XML
The XML data type field takes eXtended Markup Language code.
•Formula
A Formula data type field contains a formula of some sort; chemistry, mathematical, etc. When editing, and this field is selected, the Formula builder will be loaded in which the user can construct a formula to insert. When this field is viewed, the formula is rendered.
Overview
1.Field class selection
Each radio button represents a field class. When a radio button is selected, an Existing fields drop-down list will be populated with the respective field class.
2.Existing fields drop-down list

•Field name

•Field type
Displays the current field type. There is a distinction between Text and Pre-set fields. A Text field is a field that can contain generic text. A Pre-set Field can only contain one of a certain number of pre-set values that are set when creating the field. Fields with pre-set values are displayed as a drop-down list when creating or editing a Record. Pre-set values can be created and edited on the Pre-set panel.
•Field data type
Displays the current field data type.
•Maximum length
Used to specify the maximum number of characters or digits that may be entered in the field that is being edited or created.
4.Pre-set panel
When a field with a pre-set data type has been created or selected for editing, the Pre-set Panel will be displayed. The pre-set values for the field can be created or modified in this panel.
•Existing Attribute
All the existing pre-set values for the field are listed in this drop-down box. The values can be selected for editing.
•New Attribute
Clicking this button clears the text boxes and allows for the creation of a new pre-set value.
