The 'Database' tool in SOL provides a way for tutors and students to collect and share a selection of online items, for instance images or documents.
It allows the tutor and/or students to build, display and search a collection of entries (i.e. records). The structure of the entries is defined as a number of fields which can include text and numbers, URLs, images, uploaded files and other more advanced fields such as checkboxes, radio buttons, dropdown menus, etc. You can also use the database templates.
