About Flex Data Management Service
The Flex Data Management Service is a Flex Data Services feature that lets you create
applications that work with distributed data. This feature lets you build applications that
provide data synchronization, data replication, and occasionally connected application
services. Additionally, you can manage large collections of data and nested data relationships,
such as one-to-one and one-to-many relationships, and use data adapters to integrate with
data sources.
The Data Management Service, Message Service, and RPC services of Flex Data Services are
based on an underlying messaging infrastructure, as the following example shows:
For more information on the Message Service, see “About the Flex Message Service”
on page 73. For more information about RPC services, see “About RPC services” on page 74.
The messaging infrastructure lets a Flex application connect to a message destination, send
messages to it, and receive messages from other messaging clients. Those messaging clients can
be Flex applications or other types of clients, such as Java Message Service (JMS) clients. JMS
clients can publish and subscribe to the same message destinations as Flex applications. This
means that Flex applications can exchange messages with Java client applications.
The messaging infrastructure uses a server-side message service and a corresponding message
API on Flex client-side applications. Flex client applications pass messages through a set of
endpoints on the server, and the message service then routes the messages to a topic. The
message service can then broadcast messages back to the endpoints and then to client
applications that are subscribed to the topic.
Flex Data Services also expose the messaging infrastructure as the Flex Message Service so that
you can build your own applications that take advantage of it. For more information, see
“About the Flex Message Service” on page 73.
