1 From business need to implementation Design the right information solution Davor Gornik Product Manager

2 Agenda Relational design Integration design Summary

3 Relational design

4 Data modeling in your development process Cust Order Business model Persistent information Information model System architectural model Data access SQL code Data implementation model Software implementation model DB2 DB2 UDB

5 Common requirements

6 Logical data model

7 Tie business requirements to data model

8 Transformation to physical data model

9 Physical data model

10 Update data server from model Compare model with data server Decide selectively on update Create update code for the data server Execute the code with the data server

11 Integration design

12 Information integration design Sales Sales Model Target Model Step 4: Extend target model Cust Order Glossary Step 3: Create target model from business glossary Shipping Shipping Model Step 6: Decide about deployment platform Federated schema Accounting Step 1: Annotate existing information infrastructure Accounting Model Step 2: Map data sources to each other (optional) Step 5: Map data sources to target DataStage Step 7b: Generate federation code Step 7a: Create warehouse Export models to DataStage for ETL

13 Annotating existing information infrastructure Explore the database structure using Database Explorer and Properties window Connect to an existing database using Database Explorer

14 Annotating existing information infrastructure Document and annotate elements of the model Create a physical data model from schema by dragging to Data Project Explorer Create context related diagrams from the model for better understanding

15 Import business glossary Import model from WebSphere Business Glossary Convert the dependency of terms to entities, attributes and relationships Create and expand the naming model

16 Mapping of data sources Increase understanding of data sources by mapping them to each other Define transformations between source and target if needed

17 Mapping of data sources Configure the mapping discovery algorithm Define and include a glossary to increase quality of results for mapping discovery

18 Creating data model Create a logical model for the target schema Define and document attributes

19 Transform the logical data model to the target model Transform the logical model to physical data model Create diagrams to explain schema

20 Mapping of data sources to target Specify mapping groups and join expressions Define the mapping between each of the source data models and intended target data model

21 Generating WebSphere Federation Server code Define schema and name for generated nicknames and views Generate script for selected target

22 Generating database code Understand complete specification for views Explore federated model with specified views and nicknames Use and change generated script as needed

23 Export target model Export the model to WebSphere Metadata Server Use the model as target when implementing ETL job
