Agenda

Topic: Understanding the major data

connectivity middleware standards

Topic: Understanding why DataDirect is

a must for data connectivity

Topic: Q&A


At the end, you should understand:

What JDBC, ODBC, ADO.NET, SQL/XML, and XQuery mean

Why the “free” implementations will cost your organization far more than you expect

Why DataDirect is the de facto standard for data connectivity middleware

Data Access Middleware Standards

ODBC OLE DB/ADO ADO.NET JDBC SQL/XML XQuery/XQJ


ODBC

Provides a common API to all relational data stores

Cross platform Initially a Microsoft standard based on a

draft pre-release of the X/Open SQL Access Group CLI

ODBC 3.0 aligns with the ISO and ANSI CLI standards

JDBC

JDBC is a Java™ interface for accessing SQL data sources

Based on ODBC, Open Group SQL CLI, and ANSI/ISO CLI

JDBC 1.0 designed for basic usage with emphasis on ease of use

JDBC 2.0 enhanced for advanced features and server-side use

JDBC 3.0 goal was to “round out” API by providing missing functionality


DataDirect Connect for JDBC

Leader in specJAppServer benchmark performance for:– SQL Server

– Oracle

– DB2 All drivers are J2EE 1.2, 1.3, and 1.4

certified


ADO.NET

ADO.NET is a .NET standard for accessing data sources

ADO.NET is the only native data access framework for .NET environments

ADO.NET has nothing to do with ADO!


DataDirect Connect for .NET

DataDirect provides the only 100% managed code environment for .NET™ data access

Exclusive partner for Microsoft tests suites

Fast!

Connect for SQL/XML

SQL 2003 provides XML extensions– Called SQL/XML

Exposed as an extra-featured JDBC driver Databases supported:

– DB2– Oracle– SQL Server– Informix– Sybase


SQL/XML – creating XML from SQLselect c.CustId, xmlelement(name customer, xmlattributes(c.CustId as id,c.Name as name), xmlelement(name projects, (select xmlagg(xmlelement(name project, xmlattributes(p.ProjId as id,p.Name as name))) from Projects p where p.CustId=c.CustId))) as "customer-projects"from Customers c

CustId customer-projects 1 <customer id="1" name="Woodworks">

<projects> <project id="1" name="Medusa"/> </projects> </customer>

… … 4 <customer id="4" name="Hardware Store">

<projects> <project id="2" name="Pegasus"/> <project id="8" name="Typhon"/> </projects> </customer>

XQuery

XML query language developed in the W3C XML-centric

– Treats all data sources as XML

– Allows efficient XML views of non-XML sources such as relational databases

– Native XML Programming Designed for data integration

– A single query can address several sources General purpose, powerful query language with full

support for creating, querying, combining, and restructuring XML


DataDirect XQuery

Database-independent XQuery Supports SQL and XML sources Same design principles as our existing products

– Cross-platform– Standards-based– Embeddable – no need to install servers– Supports the latest features of each standard and each

database Expected soon after release of XQuery
