In syntax, JADE is very similar to [[Pascal (programming language)|Pascal]]; its syntax is based on the language [[Modula-2]], which was derived from Pascal. While it includes innovations lacking in Pascal or Modula-2, it lacks certain features of other modern object-oriented languages such as C# and Java.<ref name="obscure">{{Cite | In [[Syntax (programming languages)|syntax]], JADE is very similar to [[Pascal (programming language)|Pascal]]; its syntax is based on the language [[Modula-2]], which was derived from Pascal.

Schemas serve the same purpose as [[Java package]]s or [[namespace]]s in .NET, but have a hierarchy, and inherit classes from superschemas. This becomes useful especially when programming using the [[model–view–controller]] methodology, as model classes can be put in one schema, then the controller and view classes can be built on top of the model classes in a subschema.{{Citation needed|date=January 2026}} | ||

JADE programs are developed using a user interface that allows programmers to visually create [[class (computer science)|classes]] and define their properties and methods. Instead of locating methods in large files, programmers select the method they would like to edit and only the code for that particular method is displayed. Also instead of compiling all the code of a program at once, in JADE, each method is compiled individually as soon as the method is completed, meaning code can be checked immediately. | JADE programs are developed using a user interface that allows programmers to visually create [[class (computer science)|classes]] and define their properties and methods.

All the code for a JADE application is stored in its object-oriented database. This allows for multi-user development as the database maintains [[concurrency control]], and with each piece of the code being a separate object in the database, it is often possible to [[recode]] a system while it is live and online as long as the parts of the system being changed are not in use. | All the code for a JADE application is stored in its object-oriented database.

Along with Web services, JADE can also interface with other programs through language APIs (including .NET, Java, C/C++), DLL calls, ActiveX/COM objects and .NET assemblies. This allows other programs to access objects and execute methods, and can be used to provide a different interface to a JADE application. JADE 6.2 provided a Java API, .NET Assembly integration and the ability to run Smart Thin Clients on [[Windows]] Mobile devices. JADE 6.3 provides an API for [[List of CLI languages|.NET languages]]. | |||
