The image admin068.gif illustrates that a service can have more than one instance. It also illustrates that one instance can be in more than one service. It shows a database and eight instances, and then the following mappings:

• Instance 1 maps to Service A

• Instances 2 and 3 map to Service B

• Instance 4 does not map to anything

• Instance 5 maps to Service C

• Instances 6 and 7 map to Service D

• Instances 7 and 8 map to Service E

In this figure, Instance 7 maps to both Services D and E.
