Adapters and Business Objects

A Single Adapter Can Process Data Going In Both Directions A Single Adapter Can Handle Many Types Of Transactions (E.G.

Orders, Customer Data, Etc.) An Adapter Can Use A Single Business Object For Multiple Operations

(E.G. Create, Update, Delete, Retrieve) An Adapter Is Driven From Meta-data In Business Objects Business Objects Are Stored As XML Schemas

Business Objects

Core Function of a Business Object• Model the data that needs to pass among

systems• Tag the data with a simple operation (“verb”)

• Create, Retrieve, Update, Delete• Exists, Retrieve By Content• Other business logic methods

…

33 The Business Object (BO) contains:

1. Name suggesting the represented entity

2. Verb that represents the “action”

3. Data

Business Object Designer



10

Business Object Discovery Agents

Object Discovery Agents (ODA) tools perform object discovery within an application or application specific datasource and build generic (WBI) business object definitions for you

ODA tools are available for many Adapters Oracle Applications JDBC (Oracle, MSSQL, DB2, etc.) I2 ADW SAP PeopleSoft Siebel

More are being developed Object Discovery Kit (ODK) allows a developer to develop their own ODA

for custom or legacy systems Some Adapters have specialized tools to build Business Object Definitions



11

Mapping Business Object Attributes

WBI Adapters convert between Application-Specific Business Objects and Generic Business Objects

Mappings must be defined for each Application Specific Business Object Definition

WBI Map Designer is provided for graphically associating fields between application specific and generic business objects



12

Mapping Business Object Attributes

Transformations in the mapping steps for each field are provided by the WBI Activity Editor to graphically specify transformation rules

● Nodes provided for Math, String, Database, BO field & API access, BO array manipulation, Utility functions, Conditional expression evaluation, Looping, Logging



13

WBI Adapter Components

Adapter Agent – links an application to an integration broker► Application Specific Component – interfaces to the application and understands its API and

how to retrieve and update application data► Adapter Framework – common infrastructure for all adapters that provides services for

broker interaction & communication, logging, common admin & config services, initialization Adapter Controller – runs within the WBI server

► manages list of subscribers for the adapter► transforms between application specific and generic business objects► Contains transport services for communication with the Adapter Agent

Connector Configurator – to set application specific information required to access the application and for general Adapter instance properties

The Adapter AgentResponsible for extracting data (representing a business object) from, and

giving data to, an application (or technology) on behalf of an integration broker

Event Detection & Delivery Something happens in the application, and the adapter needs to notify the integration

broker The adapter could poll for the event, or the application could send it directly to the adapter

Service Call The broker sends a request to the Adapter Agent to update a business object in the

application. The adapter must process the request and send the result back to the broker as a

response.

BrokerEvent delivery

ApplicationExample: User creates customer in application. Adapter must create a business object representing that operation and send it to the broker Service call

Code

Adapter Event Processing

Event mechanism (trigger)

AdapterFramework

• The Adapter’s application specific code detects updates to objects in the application using

• the application API• a listener component registered to the application’s callback mechanism• triggers on the application’s database• access to the application’s datasources or files

Application

•The application specific component writes entries for each update to its Event Table•Contains Name of the Business Object, Action (Create, Update, Delete), a set of key values, and a date/timestamp• Entries in Event table are moved to Archive table, useful for Event Processing errors, tracing, etc.

Application

The Adapter processes a configured number of entries from its Event Table on each Poll Interval

For each entry, the adapter checks that the Business Object name and the Verb are listed within its Subscription List (which is managed by the Adapter Framework)

If it matches, the Adapter retrieves the rest of the data for the object from the application, builds a WBI application specific business object, including the Verb.

The Adapter Framework sends the application-specific Business Object to the Adapter Controller using a configured transport channel

The Adapter Controller converts the application specific business object to a generic business object and sends it to subscribers

The Adapter Controller Maps The Generic Business Object To An Application-specific Business Object

Adapter Controller determines the transport connection to the adapter agent and sends the Application-specific Business Object

The Adapter Application Specific component creates data in the proper format for the application from the app specific business object

performs the request action associated with the Verb in the request, to update the application generates a Return-status Descriptor and a Response Business Object to the Adapter Framework

The Adapter Framework sends the application specific Response Business Object to the Adapter Controller using a configured transport channel

A Data Handler is designed to convert application-specific formatted data (“serialized format”) to WBI business objects and

vice versa.

● Data Handlers can be (re-)used from across various Adapters

● Executes within the Adapter Agent’s executing process

● Invoked for a business object to string (serialized) conversion to handle WBI business object request processing.

● Invoked for string (serialized) to business object conversion to handle application event notification.

Advantages of the WBI Adapter Framework

The WBI Adapter Framework provides…1. A runtime environment for your application specific code

2. Isolation from the adapter-broker messaging

3. Broker independence (WBI, WMQ Message Broker, WAS)

4. Potential to leverage existing IBM Data Handlers

5. Facilities for handling business objects

6. Default methods that can speed the development process

7. Feature standardization across the suite of adapters

8. Object Discovery Tools; Event Management (Event Queuing, Event Archiving, Event Identification); Bi-directional Data Exchange; Meta Data Driven
