sdos

Now all that you need to do is create a database connection, and you will be ready to create SDOs to access the database.

In an effort to simplify the J2EE data programming model, IBM and BEA teamed together to develop the concept of Service Data Objects (SDOs).

A Session EJB might have methods to produce and consume a graph of SDOs with more efficient direct access to the entity EJBs.

Reduced database overhead: At the heart of SDOs is support for disconnected working.

SDOs enable uniform access to application data and a common programming model for all data sources, wherever and however the data is stored.

With SDOs, business applications are what they were meant to be: business applications.

Service data objects (SDOs) are a very useful implementation mechanism for service data messages.

Looking at SDOs and their associated interface, you should get a clear idea of the API the SDO extension provides.

A data binding converts the transport's native message into the Service Data Objects (SDOs) expected by the components, and vice versa.

When this document is loaded into memory as a graph of SDOs, the graph will contain five data objects and two data object lists.

SCA components can be composed and can exchange data with each other in a neutral fashion by passing SDOs.

You give the Relational DAS a SQL query to execute, and it will issue the query and break the result set into a graph of SDOs.

The main technologies used are Ajax, JSF using IBM Enhanced Faces components, and service data objects (SDOs).

The PHP implementation of SDOs involves mapping to a dynamic and weakly typed language.

If sharing the same SDOs across multiple Web projects is desired, you can create a separate Java project for the SDO packages.

SDOs are Java data objects for marshalling and unmarshalling of XML data during web services communications.

SDOs are a generalization of the Data Transfer Object pattern.

There are a number of reasons why you might consider using SDOs, the main ones outlined below.

Service Data Objects (SDOs) are designed to simplify and unify the way in which applications handle data.

SDOs are the basis for the data exchange in component's interactions.

SDOs leverage the simplicity of XML without introducing the complexity of XML Schema or the performance issues of serialization.

Part 3 will describe the advanced techniques for manipulating the generated SDOs and customizing the XML-SDO transformer.

You will recall that the XML DAS gets its information about the model the SDOs must follow by reading an XML schema file.

Service Data Objects (SDOs) are designed to simplify and unify the way applications handle data.

A Session EJB provides access methods to produce and return a graph of Customer SDOs from the Customer Entity EJBs.

SMOs are patterned after Service Data Objects (SDOs).

Simple types like strings end up as primitive properties on the SDOs.

SDOs become much more capable when they are connected to form a graph of objects.

As mentioned in the introduction, SDOs rely on the existence of DASes.

Knowledge of the structure: As we have already seen, SDOs carry internal knowledge of the structure of the data they represent (the model).

SDOs are created by calling a data factory object.

SDOs are connected by references from one to another.

SDOs define the data that is flowing between components.

When using a DAS, the client works with SDOs, and is, therefore, insulated from any data source-specific data representation.

SDOs support XML schema for metadata and XML as a data source and support for using XPath expressions to get and set values.

SDOs provide a single API for manipulating data independent of the data's originating data source.

SDOs support object syntax and associative array syntax, so the properties could have been set with object syntax

There are three important ways in which SDOs add to the basic Data Transfer Object pattern

As we saw in Step 4, SDOs supports property access using the object property syntax
