Glossary

JMA

The extension *.jma is being used for model files. This file type is recognized by OMS for a model.

Model

Assembly of components to explain real world phenomena. In general is being used to express relevant system aspects in a mathematical/algorithmic form.A model is stored in an JMA file.

Component

A component is a software unit (class, module) which provides an implementation for exact modeling concept. It is context-independent both in the conceptual and technical domain.

Attribute

A data object representing a model state variable or a input parameter.

Attribute Constraint

A type of meta information about an attribute, which refers to its valid scope of values.

CBSE

Component Based Software Engineering.

Entity

A aggregate of attributes. An entity refers to the concept of a record or structure which combines different attributes.

Meta Data

Context information about data such as physical unit of an attribute, data constraints, etc.

Modeling Project

A OMS defined folder structure for component and resources.

Component Library

Collection of components ready to be used in a model. Components and related resources are packaged in Jar files.

Jar

Jar stands for Java Archive. A jar contains a collection of files such as components and can be compressed.

Java

A programming language and platform for general programming invented by Sun Microsystems http://java.sun.com. Java is the OMS implementation language.

JavaBeans

The Java Component standard.

Model Executor

An specific method to execute a model. Model executor may run model in a client rich desktop environment or on a server without a user interface.

MPath

A scheme that locates attributes within a model. Since a is internally represented in XML, MPath has many similarities XPath.

Component Editor

An editing tool to simplify attribute management of components.

Interface

An interface declares a certain behavior of a class. It is a type that specifies but never implement methods.

Property

Properties a feature of the JavaBeans component standard, allow changes of appearances and behavior at design time. Properties are private values accessed through getter and setter methods. In OMS components attributes are implemented using the property pattern.

Property Parameter Set

A Property Parameter Set is a Java property file in which the entry keys are MPath statements to reference attributes in a model and the entry values are the attribute values. Such file has the extension .pps and is an ASCII file.

Attribute Unit

Predefined unit to express or measure a quality.
