=== Primary data structures === | |||
User data is stored in Memento in '''''[[Field|fields]]''''' making up '''''[[Entry|entries]]''''' within a '''''[[Library|library]]'''''. See '''''[[Terminology]]''''' to see how this relates to other database technologies and tools. A collection of libraries is called a '''''[[Library Groups|group]]'''''. A collection of fields within a Library structure is called a '''''[[Page|page]]'''''. When data is entered into fields, an '''''[[Entry|entry]]''''' is created, so while a library's structure is made up of fields, the library's data is made up of entries. | |||

There is, however, a '''[[JavaScript field|JavaScript field type]]''' that can be used for scripting or calculation of a field value. For a full description of the language, | There is, however, a '''[[JavaScript field|JavaScript field type]]''' that can be used for scripting or calculation of a field value. JavaScript may also be used to perform functions '''[[Actions|at the touch of a button]]''' or '''[[Triggers|at various junctures in the handling of a library entry]]'''. Memento provides a rich '''[[Memento JavaScript Library|API (Application Programming Interface)]]''' for JavaScript programming. For a full description of the JavaScript language, read '''[https://developer.mozilla.org/docs/Web/JavaScript here]'''. The implementation is based on [https://www.mozilla.org/rhino/ '''the Rhino library''']. | ||
Memento also includes a proprietary scripting syntax for users to define an expression for a '''[[Calculation field]]'''. It is simpler and easier to learn than JavaScript and is generally more convenient to use, when scripting requirements are minimal. | |||
Memento is implemented using the Java 8 language. If you have esoteric questions about field value limits, arithmetic operation details, etc, you could reference the [http://docs.oracle.com/javase/specs/index.html '''Java 8 documentation'''], (but I don't recommend it). | Memento is implemented using the Java 8 language.
