Examples

Examples of conditions are:

Textual	Logical
The customer has a credit card	Customer.Credit Card has value
The job application is being processed	Job Application.Status = In Process

In the first example, the condition is evaluated as true if the Customer has a credit card, i.e. it is evaluated based on the existence of an object (Credit Card). In the second example, the condition is evaluated as true if the state of the Job Application (the object) is Active, i.e. it is evaluated based on the state of the object.

Examples of conditions on the relationships between objects are:

Textual	Logical
The person has a submitted timesheet	Person.Timesheet exists WHERE Timesheet.Status = Submitted
The customer has no accepted contracts	Customer.Contract not exists WHERE Contract.Accepted = True

These examples are evaluated based on relationships between different objects, and the state or existence of these relationships.

Conditions can be combined, i.e. one might define a logical statement about the state of an object and the relationships to other objects at once. For example:

Textual	Logical
The person is active, and has an active assignment	Person.State = Active AND Person.Assignment exists WHERE Assignment.State = Active

This example combines 2 conditions (The person is active and The person has an active assignment) into one, separated by the logical AND operator, meaning that both conditions has to be fulfilled. These two conditions might also be separated by the logical OR operation, meaning that statement is true if the person is active, or if the person has an active assignment, or both.
