Enterprise Application Integration
l Modern enterprises need more than simple BPR:– > sharing information between processes– > innovate complex processes faster– > overall data management to create knowledge
l EAI is more than middleware– Data transport– Data representation– Business rules definition and processing
» Smart routing» Event processing
– Business process definition and execution

Information Systems!
l First step in transforming data in informationl Management effectiveness with reports
» Management have access to information when they need it l Planned and ad-hoc
l 80s: the Personal Computer revolution– Data and information in the hand of the end-user
» But costs have also increased» And new coordination mechanisms are necessary
l 90s: Datawarehousing and Decision Support Systemsl 2000: information and knowledge in real-time
– Operational Data Store

Examples of main Data Quality problems
l Flawed operational data models– Inconsistent data server only simple transactions
» Names, addressee, multiple keys and bad normalization, ...
l Inconsistent operational data models– Have to be consolidated
l Data in the wrong field– Ex: text field use
l The nightmare for consolidationl Data in programs

Gestão de Informação Aula 2 - Arquitectura de Informação para o e-business Prof. Paulo Cardoso do Amaral 37 -
Data Quality
1. Parsing, a question of semanticsl Depends on the correct use of the operational data model
2. Correction3. Standardizationl Titles, genre
4. Enrichmentl When essential data is missing
5. Matchingl Eliminate duplicates
6. Consolidationl When information is really created\
7. Charging
Gestão de Informação Aula 2 - Arquitectura de Informação para o e-business Prof. Paulo Cardoso do Amaral 38 -
Datamining
l Classification – from relational to multi-dimensionalityl Association – high probability patternsl Sequential analysis – time patterns
l Cluster analysis
l Algorithmics– Probability Value Prediction– Regression forecasting– Time Series Forecasting– Decision trees – cause-effect relationships– Artificial Intelligence
» Rule induction» Rule deduction» Neural networks

Operational Data Store
l The need for information and knowledge in real-time is increasing
l The Datawarehouse is the persistent repository of explicit data, information and knowledge but it can hardly be used in real-time
l The Operational Data Store is and architectural important tool that provides operational use of Datawarehouse data
