Four tabs will display for students in a Database activity:
If you selected a Preset when creating your Database activity, students will need to complete the Preset fields.
If you do not select a Preset, you can configure the Database by creating fields or using a template.
The Text Input field will create a short-text area that is great for names, locations, etc. If you want to include a significant amount of text (eg a biography) then select the Text Area field.
To avoid the necessity of always having to create a new Database from scratch, the Database activity has a Presets feature. Presets are ready-made Database templates. You can use an existing preset or create your own, and share it with others.
