The limitation here is whether a transformation can be constructed to match the formats on either end. If one exists then great, but as the number increases then developing n-squared transforms becomes impractical. A better approach would be to pick the most common formats and require bindings and containers to support those at a minimum, with other point-to-point transforms being added as warranted.

Usage Scenarios

Let's look at a sample scenario. The business function is to retrieve all the orders for a given customer. The data exchanged between the client and server side will be Customer(s) and Order(s). Let's assume that the business objects are modeled using XML schema and the client side will talk to the server side over Web Service using Axis2. The client program decides to use SDO to represent the business data while the server side prefers to use JAXB.

• Property values are loaded from SCDLs as DOM documents
• The DOM Document can be transformed into a java object under a databinding, such as SDO, JAXB so that the component implementation code can work with the databinding directly instead of DOM.

What's a databinding?

A databinding represents a specific data format in the Tuscany runtime. Each databinding has a unique name which identifies the data format.
