Gevity – Integrate SF.com w/Oracle

PDF w/ pricing for prospect

“The Gevity Pricing Engine (GPE) takes prospect data directly from SalesForce.com via a web service and uses XQuery to join it with data from the Oracle 9i database.”

How much will it cost to outsource our HR to Gevity?

XML back to application

Oracle 9i

Human Resource DataXML from SF.com

• Users: Gevity Business Development Managers

• Purpose: Quickly produce price quotes

• Data: Human Resource Data in Oracle 9i, customer and prospect data in SalesForce.com

• Can manage accounts from any internet connection – home, office, prospect’s office, or any Wi-Fi hot spot

• Deliver through many agents – browser, cell phone, blackberry, etc

Summary

The Challenge? • Working with XML & relational data• Increasingly difficult for developers to keep up with peculiarities in

proprietary XML tools

Why XQuery? • Based on a standard• XQuery is best for manipulating data as XML• XQuery and XQJ integrates easily into their environment• XQuery simplifies merging relational and XML

Why DataDirect XQuery? • Lives in middle tier with the application• Supports Oracle 9i with XQuery, not available from Oracle• Stable product• Follows standard closer than other implementations• Interface similar to JDBC integrates easily into their architecture• <oXygen/> XML Editor for Eclipse – wanted an IDE to help with learning

curve of new language• First class support for help with queries and tuning• DataDirect’s length of time in market and financial stability

XML in ACORD format to the insurance

companies, underwriters

Need to process insurance claims and policies

Oracle9i, 10g

Customer Policy & Insurance DataResults as XML

Summary

The Challenge? • Software vendor working with XML & relational data• Data in Oracle 9i/10g, MS SQL Server, and DB2 databases• Must work with any Application Server and cannot be limited by any other

software (must be easily embeddable)

Why XQuery? • XQuery is best for working with relational and XML data, no conversions• Simplified merging relational and XML• Develop application faster• Performance is better than other technologies

Why DataDirect XQuery? • Supports multiple database versions (for example, Oracle 9i and 10g)• Provides database vendor independence• Easily embeddable; requires no other platforms or products• XQJ interface easy to use

Integrating Other Data Sources“I have test data in XML and CSV files, and my product data is relational. I need help to integrate these for reporting…”

Reporting Application using XQuery

Summary

The Challenge? • Working with XML, relational data, and other data sources

Why XQuery? • XQuery allows you to query anything that can be represented as XML, no

need for conversions • Simplifies application development (easier, less code)

Why DataDirect XQuery? • Can query XML, relational, and other data sources

• Comma/Tab/Character Separated Values• dBase• HTML• RTF• EDI.. and a lot of them (X12, EDIFACT, IATA)• Custom URI resolvers for proprietary data sources

• Scalable and performs very well compared to other solutions. • No other software limitations and requires no other software/platform

purchases.

Querying Large XML files

XML

“We’ve got very large XML documents (3-5G), and can’t find anything to process them successfully.”

Web-based reportingapplication – traffic accidents

XML from web serviceTransient Reporting Data

Results as XML

Summary

The Challenge? • Out of memory errors with XML files (>100MB)

Why XQuery? • Transient reporting data is XML• XQuery simplifies application development

Why DataDirect XQuery? • Only product they’ve found that doesn’t get out of memory errors

processing their XML files (3-5G)• Performance compared to other XQuery products such as open source is

very good – often half the time or less.

Customer Benefits

Why do customers choose DataDirect XQuery?

• Productivity• The easiest way to develop applications/reports when dealing with various data

sources (relational, XML, and legacy data sources).• Dramatically reduced development time over alternative approaches.• Less maintenance effort (~cheaper).• Stability for developers through our standards-based XQuery and XQJ

implementations.• XML tools for query development and testing – to get developers productive quickly.

• Performance• Faster execution time with XQuery as compared to other technologies. • Special optimization, mediation = best possible XQuery performance. • XML streaming drastically reduces the amount of memory required when processing

large XML documents.

• Flexibility• Easily embeddable; does not require any other product or application server. • Freedom from database vendor and database version.
