  1. Oracle SQL Developer Data Modeler Overview David Last, Oracle UK

  2. The following is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract. It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions. The development, release, and timing of any features or functionality described for Oracle’s products remains at the sole discretion of Oracle.

  3. Agenda • Why Model? • Oracle SQL Developer Data Modeler Overview • Feature Highlights • New Features • More Information

  4. Why Model? • Top Five Reasons to Model • Easy to Change • Communication Method to Gather Requirements • Business Rules Validation • Target User Involvement • Documentation/Training

  5. Oracle SQL Developer Data Modeler Overview • No cost diagramming and data modeling tool – standalone or within SQL Developer • Single tool for different users and functionality • Modeling across platforms within one integrated system • Business rule and process flow documentationand verification • Standards-driven DDL script generation • Migration support from other tools

  6. Oracle SQL Developer Data Modeler Overview • Technology and Architecture • Java based • Common IDE Framework • Metadata stored in XML Files • Database support • Oracle 9i, 10g, and Oracle 11g • Third-party databases: Microsoft SQL Server, DB2, UDB • Platform support • Windows • Linux • Mac OSX

  7. Oracle SQL Developer Data Modeler Overview Strategy and Analysis Import Models Domains Data Type DFD ERD Multidimensional Logical Reporting Database Design Physical Star Schema Relational DDL Script Data Dictionary

  8. Logical Modeling • Model entities, attributes, relations and entity type hierarchies • Transform logical to many relational and multi-dimensional models • Configurable forward and reverse engineering • Provide different modeling notations and displays of same model • Use subviews to work on subset of model • Data Model – Entity Relationship Diagram

  9. Logical Modeling • Model external agents, processes, information flow and information stores • Different process types: primitive, composite and transformation • Decompose a process into lower level DFDs • Depict information flow from one object to another • Process Model – Data Flow Diagram

  10. Relational Modeling • Model tables, columns and foreign keys • Map one logical data model to one or more relational models • Configurable forward and reverse engineering • Use subviews to work on subset of model

  11. Working with Diagrams • Autoroute vs. Manual mode • Context-sensitive windows

  12. Working with Objects • Properties Window

  13. Forward and Reverse Engineering • Engineering options: General, compare/copy and synchronization • Include design glossary and naming standards • Transformation Logical Relational Relational Physical Physical

  14. Physical Modeling Relational • One relational model for many physical models • Documents tablespaces, users, stored procedures • Apply properties to many elements at once • Supports • Oracle9i, Oracle Database 10g and Oracle Database 11g • Microsoft SQL Server 2000 and 2005 • IBM DB2/390 and DB2 LUW Physical

  15. Custom Design Rules and Transformations • Use scripting engine of choice • Create user defined transformation scripts • Apply multiple scripts or rules • Define Rule Sets • Create Libraries

  16. Modeling Data Types • Support for SQL99 (Object Relational Modeling) • Distinct Types • Structured Types • Collection Types • Used in logical and relational models • Included in import • Generated in DDL

  17. Multidimensional Modeling • Model Cubes, Dimensions, Levels and Hierarchies, Measures and slices • Start from ROLAP, XMLA or from scratch • Generate Oracle Analytical Workspaces

  18. Importing Metadata • Import using direct connections • Oracle Database • Microsoft SQL Server • IBM DB2 and UDB • Generic JDBC based dictionary (MySQL, Teradata) • Oracle Designer repository • File import • DDL • Domains • Other Modeling tools (CA ERwin) • Multi-Dimensional (Cube views, Microsoft XMLA)

  19. Export and Code Generation • DDL generation options • Design Rules • Object selection • Drop objects • Name Substitution • Table scripts • Standard database DDL scripts • Oracle • IBM DB2 and UDB • Microsoft SQL Server • Reporting Repository export • Multi-Dimensional Oracle AW, Cube Views and XMLA

  20. Controlling the Design Environment • Defaults used during creation, manipulation, generation of all models • Naming Standards used during creation and transformation • Diagramming properties • Preferences

  21. Controlling the Design Environment • Administer cross model objects • Facilitates common tasks • Define abbreviations and glossary words • Customize and verify Design rules • Compare and merge models • Tools Options

  22. Collaborative Development Overview WorkingDirectory WorkingDirectory Check out Open/Modify Check Out Commit Changes Commit Changes Merge Changes Open/Modify Commit Changes Subversion Repository Make More Changes User 1 User 2 Version History V1 V2 V3 V4

  23. Collaborative Development • Use Versioning Navigator to connect to Subversion repository • Checking in Design using Data Modeler or External client • Multiple users check out designs • Pending Changes dialog provides feedback to all users • Commit changes to repository • Manage conflicts • Review/Manage Version History

  24. Reporting Options • Integrated reporting • Generated in RTF, PDF and HTML formats • Repository reports • Export in Data Modeler • Run Data Modeler Reports in SQL Developer • Create custom reports

  25. SQL Developer Data Modeler Release 3.1 New Features Overview • Synchronization • Versioning • Query Builder • Diagramming Enhancements • Reporting Enhancements • National Language Support • Fully translated into 9 Languages

  26. Synchronization • “Easy synchronization" • One click synchronization between model and dictionary • Support for several connections • Supports synchronization in both directions • List of values/ranges can be extracted from column check constraint • Can exclude tracking of column order when tables are compared • No need to recreate table as alter statements are generated

  27. Versioning • Version history is available at design and system level • Lock and unlock can be done at design, model and subview level • Support for branching and merging • delayed resolution of merge conflict • tree conflicts detected in advance

  28. Query Builder • Convert between ANSI and Oracle joins. • Graphical Interface support • Build complex queries • Persist the layout of diagrams • Work with objects belonging to a specific subview • Synchronization of changes in the model with already created views • Validation of view definitions created with previous version of Data Modeler

  29. Diagramming Enhancements • Diagrams can display primary, unique and foreign key columns • Display labels in Transformation diagrams • Setting default colors and fonts for Legends

  30. Reporting Enhancements • New Reports • Structured, collection and distinct types, change requests and measurements • Reporting templates can be defined • Define report sections to include in generated report • Report for objects belonging to specific  subview • Reporting Repository • Multidimensional, business information, change requests and measurement models
