What is Object Lens ?
- a groupware system that support asynchronous communication
- a knowledge-based environment for developing cooperative work application
- Object-oriented database
Knowledge about companies, people, tasks, meeting and products
are represented by objects
- Folders are created for objects of the same types
- Users can customize their own display of objects in a folder
by selecting fields to be displayed in table form or in tree form
- Tables show the value of selected fields from the objects
- Trees show the links between objects in the folder
- Rule-based agents can be created easily by users to process information
eg. sorting new mail messages into different folders
- Agents can be triggered by events or by users
- When an agent is triggered, it applies a set of rules to
specified collection of objects such as new mail messages
- If an object satisfies the criteria specified in a rule,
specific actions will be triggered
eg. moving urgent mail messages to a specific folder
- A rule contains an IF field and a THEN field
- The IF part describes a set of instances of fields
- The THEN part describes the action
- Instead of looking at information contained in the object,
Object lens can draw information from other objects.
These features can be combined to create a variety of cooperative
