An action is used to indicate an event on an item. An action consists of one or more phases. Each phase represents a progression of the action. Actions can be applied to items any number of times.
Action Instance
Each time an action's phases are applied to an item it is considered an instance of the action. For example, a book can be lent out multiple times. Each time the book is lent out is considered an instance. When the book is returned it is applied to a specific instance.
Action Phase
An Action Phase represents one part of an action. Each phase has its own set of attributes for keeping track of additional information.
An attribute, or field, is a piece of data you can track for an item such as name, price, count, date of purchase. You can create any number of attributes and specify the type of data it holds such as text, date, and currency.
A category defines a common set of attributes and is a logical grouping of items. All items must belong to category. You can create any number of categories each with their own set of attributes. Categories can also define multiple levels of groups which can be thought of as subcategories. Items can be further assigned to these groups.
A collection is a set of categories. These are optional and user defined. Collections can be used to organize your list of categories and allow you to view items belonging to those categories.
A container is part of a location. Containers can have their own subcontainers.
A database represents a set of data. Each database has its own categories, locations, actions, and items.
A filter is a way to view items that match certain criteria. A filter can be applied to a list of items. Examples might include viewing movies from a specific genre or viewing books from a certain author.
A group is part of a category. Groups can have their own subgroups. Items can be assigned directly to a category or it can be further assigned to one of its groups.
An item is anything you want to keep track of. Track stamp collections, books, movies, warehouse items or any item you can think of. Items inherit attributes from its category. You can add custom attributes to an item if needed though this is uncommon.
A location is a way to group items together based on their physical location. The location has no effect on the attributes of an item. Locations can also define multiple levels of containers or sublocations. Items can be assigned to any one location or container.
A sort is a way to view items in a different order. A sort can be applied to a list of items. Items can be sorted by any attribute in either ascending or descending order.
