Library consists of several Pages with Fields. By default, there’s one Page — Main, — but you can add as many as needed. Pages are used to divide data inside the table. In addition to Pages, you can add Subheaders to group several fields.
Field is a column in the Library that defines the attributes of data. Memento Database provides you with 30 types of fields that include the basic ones like integer or string, and advanced — for scripting or linking the data entries.
Also, Library may include Aggregation — special row for basic math calculations based on the data entries.
And finally, an entry is a record with data. After the library structure is finished, you can fill it with entries defined by fields.
