Web Services Enabling Existing Data

Radically Simplify and Accelerate Web Data Service Development

For many companies, existing data is a major obstacle in the path to SOA. Existing data is complex, diverse and spread across the extended enterprise in various technology and application silos. Each source has its own access mechanisms, syntax, security, etc. Few are structured properly for SOA consumption and thus require federation, transformation, and other specialized techniques.

Further, in a data integration world dominated by SQL specialists, time spent mastering XML structures and SOA development techniques can severely limit development productivity. And putting together a development team with the right blend of SQL and XML skills can be costly, if not impossible.

Automated tools for web data service development can overcome these challenges.

The Benefits of Development Automation
The benefits of automated code generation are well known and fully apply when developing Web data services. These include:

• Faster initial development
• Higher quality
• Better performance
• Fewer specialized skills required
• Easier modifications
• Lower total costs

Composite Radically Simplifies Web Data Service Development
The Composite Information Server is a complete development suite that radically simplifies Web data service development. You can use Composite when developing a full service-oriented architecture (SOA) or simply delivering data to SOAP clients.

• Web-service enable your existing data in three simple steps. Automate your web data service development to save time, avoid unnecessary errors, and reduce costs.
• Easy to use. Leverage a well known modeling paradigm to get your existing staff up to speed quickly without having to become XML, WSDL, and SOAP experts.
• High performance. Query data in the most optimized fashion to protect existing data sources.

Composite Lets You Build Web Data Services in Three Steps
With Composite you can build a web data service in minutes. The basic process requires just three simple steps:

Step 1: Connect to your existing data
Composite allows you to easily access any number of data sources, including RDBMSs, packaged applications (SAP, Siebel, Oracle EBS, PeopleSoft, Salesforce.com), mainframes, flat files, XML documents, and even existing Web services using pre-built adapters. You can introspect your environment to reveal all the data sources that you have available to use, so you don’t have a be a DBA in order to get started

Step 2: Model the new Web data service
Composite provides easy-to-use graphical design tools to build your Web services. You can build a simple data service that represents a single table from an existing data base. Or you can build a complex data service that federates multiple disparate data sources. Because you build and test in the same environment, you can quickly iterate your data model to get just the data your consumer requires.

Step 3: Publish the Web data service
After you have completed the data modeling process, you can publish it as a Web service at the click of a button. Composite automatically generates the WSDL formatted XML document that can be consumed by any SOAP client. You don’t need to learn XML, nor do you need to worry about performance. Composite optimizes queries and transformations for you.
