Do you Web 2.0? Find out more about how you can

take advantage of a Services Oriented Architecture to easily deliver location based information to your applications. IDS extensibility and the

new Web Feature Services in Cheetah(v11) make this possible. The new Basic Text Search that is included in IDS Cheetah will also be covered.

Web 2.0

Web 1.0 Web 2.0

Mapquest: Static view of a map, with zoom

Google Maps: Uses Ajax to provide the user with a smoother, faster experience; no waiting for server roundtrips

Ofoto: Users can upload their digital photos and get printouts

Flickr: allows users to securely manage and share their photos in an online space

Britannica Online: published encyclopedic information on the web

Wikipedia: allows users to read, write, update and delete encyclopedia entries on the web

personal websites: individually created and maintained web sites with unique URLs

MySpace: a common place to go where everybody is (or can be) your friend; allows you to post your photos, videos, music, blogs

directories (taxonomy): the web site creator decided how the information was organized

tagging ("folksonomy"): the users of the web site decide how they think the information fits into their worldview

Stickiness: focus on driving users to the site and keeping them there

Syndication: focus on disseminating content from the site out to the interested parties

Web 2.0 applications – Tim O’Reilly• Web is the platform• Harness collective intelligence• Data is the next intel inside• No more traditional release cycle – constat updates,

eternal beta– You’re updating the Service, no package to distribute and install

(Saas)

• Programming models– Think assembly

• Seamless integration with devices• Rich user experiences

10

IDS for web 2.0• Need for speed

– After all these years, performance is still the king

• Solid SQL and application dev support– Support for open source APIs

• Low TCO is desirable for all apps, including web 2.0

• Support for XML for integration (Cheetah and further)

• Data Growth -- Ability to handle large data set with large number of connections

• Reliability

IDS and PHP - Double punch!

Deploy - scalable and supported– Scalable data servers

• Common PHP driver (PDO_IBM) supported by IBM for Cheetah

– Zend Core for IBM • Has Apache webserver, PHP drivers, Zend FW, third party

libraries, samples, etc.,• One stop shop for PHP installation, rapid PHP application

development, deployment and production support– Enhanced scalability

• Zend Platform (object caching, and more) +development partnership

Quick to Develop– 100% designed for the web and Free!!!– Scripting language part of LAIP stack (Similar to LAMP)– Tools make light work

• Eclipse - PHP Development Environment (PDE)• Zend Studio v5.2 - integrated support for DB2 and IDS

– Strong Community PECL/PEAR/etc.,– Framework availability

– Zend framework, CakePHP, etc.,– Zend Core for IBM.

IDS and Perl

• Script Language• Excellent at string handling• Strong Community - CPAN• Community Supported Drivers

– DBD::Informix • version 2007.0226, with a version 2007.06xx in the works

– DBD::ODBC• IBM Supported Drivers

– DBD::DB2 • Based on CLI

– Common Driver• Plans underway

IDS and Python

• Dynamic Object Oriented Programming language

• Community already has InformixDB driver for IDS– Version 2.3 – 1st October 2006 – DB-API 2.0 compliant– Requires Python 2.2 or better– Requires Informix ClientSDK

• IBM is currently engaged in its own adaptor/driver development– Expect Python/Django details in early 2008

17

IDS and JAVA• Single JDBC driver for ALL IBM data servers • Development has primed the Java Common Client (JCC) driver

3.5 for IDS CHEETAH release• Support for Informix connection URLs, environment variables,

data source• Support for Informix basic data types• Support for all database modes• Connection using DRDA protocol• JDBC 4.0 Specification Support will be available soon• Goal is to keep existing application impacts to a bare minimum

for applications that have adhered to JDBC standards• Common Web Admin

– IBM Data Server Administrator Standard Edition– Based on JCC– Support for IDS by 2008

What’s with Ruby and why on Rails?

• Ruby: an object-oriented open source programming language– Inspired by Smalltalk, sharing features with Python, Lisp, Dylan

and CLU– Reflective and single-pass interpreted language (scripting)

• Rails (a.k.a RoR): a full stack Web framework written in Ruby– Web development made easy through “Convention over

configuration” and “Don’t Repeat Yourself” principles– Development, deployment and maintenance made easy through

patterns, structure and built-in plumbing: MVC, ORM, Migrations, Testing, AJAX, etc…

IBM Software Group

19

IBM’s offering for RoR development• IBM_DB-0.8.0 gem enables full support for Informix Dynamic

Server (IDS) 11.10 and beyond through IBM_DB Rails adapter and ibm_db Ruby driver

• Connects to IDS 11.10+ via DRDA protocol• http://rubyforge.org/projects/rubyibm/

• See also the open source ruby-informix driver developed by Gerardo Santana which supports all recent IDS versions via the SQLI protocol

Cheetah Feature Training | Confidential © 2007 IBM Corporation

Introduction

► The Web Feature Service (WFS) allows a client to retrieve and update geospatial data from multiple Web Feature Service instances.

► A WFS allows uniform access to features stored on a server:■ query a dataset and retrieve the features

■ find the feature definition (feature's property names and types)

■ add features to dataset

■ delete feature from a dataset

■ update feature in a dataset

■ lock features to prevent modification (optional – not in this implementation)



Why Use A WFS?

► Provides a generic way to access raw geographic data over the web.

► While a Web Mapping Service (WMS) returns map images a client, a WFS returns features related to a location. Eg.■ Which lakes are within a particular district?

■ Which rare species sightings occur outside of protected areas?

■ Which hospitals are located in Tokyo and are less than 97% full?

■ Which intersection/street is closest to my GPS location?

► Greater transparency and openness in mapping applications.

► Interoperability with WFS from different vendors.



IBM Web Feature Service (WFS) Datablade Module

► Supports web-based geographical programs using data stored in IDS using the Spatial or Geodetic Datablade modules

► Encodes geographical features in Geographical Markup Language (GML) 3.1.1 or 2.1.2 specification

► Based on the Transactional WFS 1.1 (WFS-T) specification from the Open Geospatial Consortium (OGC)

► Uses HTTP GET or POST methods encoded as key-value-pairs (KVP) or XML for requests and responses.

► Requires Spatial or Geodetic Datablade modules to be installed and registered in the same database as WFS Datablade module



Feature Identifiers

► All features must be uniquely identified.

► Features usually take the form Feature.ObjectID where Feature is a feature class or table, and ObjectID is a unique identifier (usually a primary key) for that class or table.

► Eg. Customer number 101 in the customer table is referenced with the feature ID of customer.101.

► This must be a single column primary key. Composite keys are not supported.
