Service-oriented Architectures (SOA)

Informix and SOA - Overview

Informix and SOA - Details

Additional Information

IBM Software Group

What is SOA?

Service-oriented architecture (SOA) helps hide the IT complexity inherent in even seemingly simple interactions

One key technical foundation of SOA are Web services

SOA is an architectural style that allows Web services applications to interoperate dynamically with one another

SOA isn’t really new, but the availability of more and improved Web services applications is making SOA much more powerful and easier to implement

SOA makes it less expensive for companies to link their business processes to those of their suppliers, vendors and other business partners

IBM Software Group

SOA Example: Internet Bookstore

Customer point of view: A book is ordered online and a few days later delivered to your house

What happens behind the scenes: Your identity must be authenticated Your charge card validated Your order acknowledged by e-mail The order sent to a distributor The book located and boxed for shipping E-mail notification that your order has shipped Hand-off to the shipper (at which point the shipper’s supply chain

management system tracks the movement of the purchase) And finally delivery and acknowledgement of receipt

How SOA comes into play Each of the applications above performs a service that is orchestrated

increasingly by SOA

IBM Software Group

What are Web services?

‘Remote Function Calls’ via Inter-/Intranet

Based on XML-formatted messages

Utilize internet protocols like HTTP (important if proxys/firewalls are involved)

Base technology for complex applications

Some reasons why Web services are successful: Loosely coupled systems

Independent from the used programming language (e.g. Java, 4GL, ESQL/C, Cobol, C++, etc.)

Easy application integration due to open standards

IBM Software Group

Why SOA now?

To keep pace with global competition: “We are taking apart each task and sending it

… to whomever can do it best, … and then we are reassembling all the pieces” from Thomas Friedman’s ‘The World is Flat’

The standards and technology are finally in place, with broad industry support

Availability of best practices for effective governance

The necessary software to get started is available today

Informix and SOA – Details


IBM Software Group

Case Study 1: Supply Chain Integration

Problem:An IDS 7 based application (manufacturer order entry system) should be integrated into the supply chain management of a world wide operating retail customer.

Solution:IDS 10 as a Web service provider In-place update of IDS 7 to IDS 10 Utilizing WORF (Web services Object Runtime Framework) with

IDS 10

Result:WORF provides Web service access to an IDS 10 Stored Procedure which is the interface to the manufacturer’s order entry system.

IBM Software Group

Informix IDS and SOA: Web services integration

IDS as a Web service provider

IBM WORF (Web services Object Runtime Facilty) support for IDS Easy IDS Web service definition based on SQL Statements

(SELECTs, INSERTs, UPDATEs and Stored Procedure Calls) Requires WebSphere Application Server or any other J2EE server

as a runtime environment Integrated easy to use test environment

IBM EGL (Enterprise Generation Language) allows easy Web service providing Easy to learn, Java based 4GL-like language

Strong .NET support for IDS and Web services integration for non-Java environments

Any Java object (Servlet, Bean etc.) could be used as an IDS Web service provider

IBM Software Group

Agenda








IBM Software Group

Case Study 2: Web service access from a Legacy App

Problem:An Informix ESQL/Cobol application should be enhanced to be able to access a credit card verification (Web-) service.

Solution:IBM IDS 10 as a Web service consumer JFoundation, Apache AXIS Framework

Result:An IDS 10 Java Stored Procedure (User Defined Routine) which accesses the remote Web service. Callable via SQL statements. Only minor changes in the ESQL/Cobol application are required since SQL is being used to interact with the Web service.

IBM Software Group

Informix IDS and SOA: Web services integration

IDS as a Web service consumer

IDS leading extensible architecture provides the perfect foundation for web service access

IDS JFoundation in combination with the Axis framework allows transparent access to web services from the Informix SQL layer

Agenda








IBM Software Group

Case Study 3: Provide Web service API for a 4GL App

Problem:An Informix ISV gets the customer requirement to add an Web service API to an existing Informix 4GL legacy application.

Solution:Conversion of the 4GL application to IBM’s Enterprise Generation Language (EGL) and utilization of EGL’s Web services support Rational Application Developer, 4GL to EGL conversion tool, EGL Web

services, IDS 10

Result:After converting the 4GL App to EGL, some former 4GL functions (now in EGL) could be offered as Web services w/o any major changes to the original code.Positive side effect: Due the Java based EGL language, parts of the application could be web-enhanced and also could be deployed to more platforms (e.g. Windows)

IBM Software Group

Informix 4GL and SOA: Web services integration

Informix 4GL applications

Consider a conversion to Enterprise Generation Language (EGL)

EGL allows easy Web service provision and Web service access

Web service support is part of the EGL language!

Easy to learn, Java based 4GL-like language

EGL supports character based (4GL-like), batch and web applications (soon also GUI applications)

An included conversion utility allows an easy 4GL to EGL conversion process

Additional platform deployment support (e.g. Windows)

IBM Software Group

Web services: Characteristics

Web services are self-contained On the client side only a programming language with HTTP and XML

support is required The client and server can be implemented in different environments

Web services are self-describing The definition of a Web service message format travels with the

message No external metadata repositories or code generation tools are

required

Web services are modular Simple Web services can be aggregated to form more complex Web

services E.g. by using workflow techniques or by calling lower layer Web

services from a Web service implementation.

IBM Software Group

Web services: Typical Categories

Business information A business shares information with consumers or other businesses Examples: news streams, weather reports, or stock quotations

Business integration A business provides transactional, "for fee" services to ist customers Examples: bid and auction e-marketplaces, reservation systems, and

credit checking

Business process externalization A business differentiates itself from its competition through the creation

of a global value chain The business uses Web services to dynamically integrate its processes Example: associations between different companies to combine

manufacturing, assembly, wholesale distribution, and retail sales of a particular product.

IBM Software Group

Web services: Standards

An extensible Web service description language... WSDL

A limited number of protocols being used... HTTP GET/POST

SOAP

An Web service directory protocol... UDDI

A commen, open foundation... XML

IBM Software Group

Web services: Standards (cont.)

IBM Software Group

Web services: A simple SOAP Message

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/1999/XMLSchema" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance">

<SOAP-ENV:Body>

<ns1:getCustomer encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="urn:placeOrder">

<Customer_num xsi:type="xsd:int">106</Customer_num>

</ns1:getCustomer>

</SOAP-ENV:Body>

</SOAP-ENV:Envelope>

IBM Software Group

Web services: Best Practices

Do not use Web services between layers of an application or e.g. within a Java application server. The parsing of every Web service message is very costly and will slow down your application.

Do not use Web services if you’re not exposing external interfaces e.g. for interoperability or if you don’t use an XML document based workflow.

Use Web services on the edge of your application server to expose external APIs or if you need to execute remote calls through a firewall.

If you have a need to execute function calls between Java application servers you might want to consider other protocols, e.g. RMI/IIOP.

IDS and XML: XML Generation with UDRs

Based on the extensibility features of IDS 10 (DataBlade Technology)

Basic building block is the genxml() routine

Code can be found on the IBM Informix Developer Zone (Author: Jacques Roy)

http://www7b.software.ibm.com/dmdd/zones/informix/library/techarticle/0302roy/0302roy2.html

SQL Statement:

SELECT genxml("customer", customer)FROM customer;

Output of the Statement on the left side:

<customer><customer_num>101<//customer_num><fname>Ludwig </fname><lname>Pauli </lname><company>All Sports Supplies </company><address1>213 Erstwild Court </address1><city>Sunnyvale </city><state>CA</state><zipcode>94086</zipcode><phone>408-789-8075 </phone></customer>

genxml() UDR example

IBM Software Group

IDS and XML: Web DataBlade

Since version 4.13.xC2: XML support builtin! New attributes for the MISQL tag: XMLDOC, XMLROW, XMLVERSION

Focus on XML output (XML input possible in combination with XSLT DataBlade)

XML templates are stored in IDS Allows usage of IDS server features like ER, HDR or Onbar!

Perfect companion to the XSLT DataBlade IBM Informix Developer Zone article (Author: Susan Cline)

http://www7b.software.ibm.com/dmdd/zones/informix/library/techarticle/0303cline/0303cline.html

<?MISQL SQL="select code,desc,ecomm,total from ecommerce;" XMLDOC="TABLE">$1<?/MISQL>

<?xml version="1.0" ?> <TABLE><ROW ID="1"><code>311</code> <desc>Food Products</desc> <ecomm>54837.00</ecomm> <total>434261.00</total> </ROW>.... additional output not shown</TABLE>

Web DataBlade template example

IBM Software Group

IDS and XML: XSLT DataBlade

IDS 10 DataBlade, based on libxslt, the Gnome XSLT library

Available via IBM Alphaworks http://www.alphaworks.ibm.com/tech/xsltblade

Creates several UDRs which take two parameters: an XML document and an XSL stylesheet

xslt_udr (returns LVARCHAR)

xslt_udr_AsClob (returns CLOB)

xslt_udr_AsHtml (returns HTML – Web DataBlade type)

select xslt_udr(s.style_doc, x.xml_doc)

FROM style_sheets s, xml_docs x

WHERE s.style_title = 'quote.xsl' and x.xml_title = 'ecommerce.xml';

XSLT DataBlade usage example

IBM Software Group

IDS and XML: JAXP Support (Informix JDBC Driver)

JAXP = Java API for XML Parsing

Part of the current Informix Type 4 JDBC driver

The API has two subsets SAX

DOM

plus a plugability layer (to standardize access to the SAX or DOM layer)

Facilitate storage and retrieval of XML data in IDS database columns Methods used for storage ensure that only valid XML data are stored

Methods used for retrieval assist in converting XML data to DOM objects or Input-Source type (can be used for SAX or DOM methods)

The Informix JAXP API supports all IDS 7 and IDS 10 text data types (incl. TEXT, CLOB and LVARCHAR)

IBM Software Group

IDS and XML: CLOB/TEXT/LVARCHAR data types

All IDS text data types can be used for XML storage

Typically used for storage of complete documents or fragments Archived copies of generated documents for legal purposes

Device independent publishing

Temporary storage of XML fragments

Can be easily combined with JAXP API for XML parsing

XSLT DataBlade for transformation

Web DataBlade for publishing

Text Search DataBlades for searching (e.g. Verity Text Search)

CLOB/LVARCHAR allow seamless replication (ER, HDR)

IBM Software Group

IDS and XML: Spatial DataBlade 8.20

Since version 8.20 the Spatial DataBlade supports the conversion into GML (Geography Markup Languge, based on XML)

Function SE_AsGML(ST_Geometry) (returns ST_Geometry)

Returns only XML fragments, not complete documents!

CREATE TABLE mytable (id integer, location ST_Point);

INSERT INTO mytable VALUES(1, ST_PointFromText('point (10.02 20.01)',1000));

SELECT SE_AsGML(location) FROM mytable WHERE id = 1;

<gml:Point srsName="UNKNOWN"><gml:coord><gml:X>10.02</gml:X><gml:Y>20.01</gml:Y></gml:coord></gml:Point>

SE_AsGML() function usage example

IBM Software Group

IDS and WebSphere MQ

WebSphere MQ: Reliable messaging infrastructure for SOA applications

Easy IDS / WebSphere MQ integration via WebSphere MQ DataBlade

New WebSphere MQ API for IDS 10, modelled after an existing DB2 MQ API

Allows an Informix application to easily interact with a WebSphere MQ based infrastructure

Additional Virtual Table Interface (VTI) support for simple SQL-/Table-based access to WebSphere MQ queues!

Comes bundled with IDS 10

IBM Software Group

WebSphere MQ DataBlade: Examples

execute function MQSend('AMT.SAMPLE.SERVICE','AMT.SAMPLE.POLICY','Hello Queue');

(expression)1

1 row(s) retrieved.
