1. Introduction
1.1 Welcome
Welcome and Thank-you for choosing Cohesion. Cohesion is an Advanced Semantic Net Modelling tool packed with a multitude of features, including :
Modelling Language Creation Cohesion facilitates the creation of custom modelling languages. This is achieved by the user fully specifying new base Meta-Model and Notation(s)*. These can be extensions or modifications of existing modelling languages.

It is also possible to create an entirely new modelling language. Cohesion is not just limited to using OML and UML.

*Several notations can be made for a particular meta model, allowing customised looks for the meaningful meta-information.
Create and Change Models Models can easily be created using Cohesion's advanced modeller.

Advanced Feature : change Notations on the fly to see how they look!
User management Cohesions user management features enable secure remote-system access control.

Users have associated privileges that allow/disallow interaction with the server repository*, giving users ease for workgroup features.

*Note that because of cohesions open and extensible code base the privilege system can be utilised by any extensions to the product.
MessagingCohesion supports sending of both E-Mail and Instant messages and the viewing and storage of Instant messages from within Cohesion.
Address bookBoth a locally stored and server stored Address Book can be maintained. Now you can move from computer to computer, and your Address Book virtually comes with you.
File ManagementBoth projects and models can be stored locally for individual use or stored remotely so that a number of people can access them.

If a more than one person uses a remote file, then a Concurrent Versioning System is used to maintain one master copy, and changes made are integrated into this copy.

Users do not need to use any file-locking and if a conflict occurs, one person needs to decide which parts of the conflicts to use.

1.2 Who should read this guide ?
This guide is for :
  • Software Developers
  • Software Designers
  • Quality Engineers
  • System Administrators*

*Cohesion when used in an network environment requires at least one assigned Administrator. Administrators should also refer to the
Cohesion Administration Manual

1.3 What does this guide cover ?
This Client User Guide provides an introduction to the Cohesion client.

It specifies the minimum system requirements and detailed installation requirements for the Cohesion client on Windows 9X / NT and Unix based systems.

NOTE: Operation of Cohesion on Unix based systems has not been extensively tested.

It describes Cohesion's Main Window, menu items and detail the steps and provide screen shots on :
  1. Starting a Cohesion client
  2. Connecting to a server
  3. Creating a new Meta-Model and Notation
  4. Logging Out and Quitting Cohesion
  5. Using Cohesion's Online Help

This guide also contains a How Do I? section that shows you how to perform the most common tasks in Cohesion, e.g. Sending an E-mail.

Use this guide to prepare you for using Cohesion. If you are after detailed steps on how to perform a task that is not covered in this manual, please consult Cohesion's Online Help, see 5. Using Cohesion's Online Help.

1.4 Conventions used in this guide
This guide will adhere to the following conventions,
Cohesion screen shots Where screen shots are used, they will be given an informative description and a figure reference number that represents which section the screen shot is located in and the number of that screen shot in that section,
i.e. Figure 2.3 - 2 represents the 2nd screen shot of the section 2.3

All screen shots will be labelled with single characters ranging from A to Z that will represent a certain part of the screen shot. These labels will be referred to in the descriptive text that follows the screen shot and will appear as, (A) (B) (C)...(Z).

2. Concepts and Definitions
This section explains the terms and concepts that are used throughout Cohesion :

Term Description
Modelling Language A modelling language is comprised of
1. a Meta-Model (see below), e.g UML: Unified Modelling Language
and
2. a Notation (see below) , drawing objects that graphically represent the Meta-Model.

When a Modelling Language has been defined, Models can be constucted based upon the Modelling Language.

Users of Cohesion have the facility to create their own Modelling Language
Meta Model Encapsulates the meaning of a Modelling Language.

Each object in the Modelling Language is assigned a name and attributes.

Meta Models are comprised of the abstract concepts of Nodes, Arcs and Rules
Notation A Notation specifies for each Node and Arc the graphical representation to be used when drawing Models.

This is especially useful for people who like to customise the look of their Models.
Nodes Nodes, conceptual objects contained in the Meta-Model. For example, 'Class' is a Node contained within the UML Modelling Language.
Arcs Arcs are connections between Nodes. For example, 'Association' is an Arc common in many Modelling Languages.
Rules Rules, specify the interaction of Nodes and Arcs within the Meta-Model. For example you can specify which Nodes are allowed to connect to each other.
Terminator A small graphic which is placed at the end of an arc to give it a meaningful graphic represetnation, used when creating a notation.
Model A diagram constructed from a Modelling Language.
Workspace Contains a list of Projects.
Project A collection of Models.
