Agenda

• Why Model?

• Oracle SQL Developer Data Modeler Overview

• Feature Highlights

• New Features

• More Information


Why Model?

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



• 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



• 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

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


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

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


Working with Diagrams

• Autoroute vs. Manual mode

• Context-sensitive windows


Working with ObjectsProperties Window


Forward and Reverse Engineering

• Engineering options: General, compare/copy and synchronization

• Include design glossary and naming standards

Physical Modeling

• 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

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


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


Multidimensional Modeling

• Model Cubes, Dimensions, Levels and Hierarchies, Measures and slices

• Start from ROLAP, XMLA or from scratch

• Generate Oracle Analytical Workspaces


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)


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


Controlling the Design Environment

• Defaults used during creation, manipulation, generation of all models

• Naming Standards used during creation and transformation

• Diagramming properties

Preferences


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

SQL Developer– Create custom reports


SQL Developer Data Modeler Release 3.1

• Synchronization

• Versioning

• Query Builder

• Diagramming Enhancements

• Reporting Enhancements

• National Language Support– Fully translated into 9 Languages

New Features Overview


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


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


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


Diagramming Enhancements

• Diagrams can display primary, unique and foreign key columns

• Display labels in Transformation diagrams

• Setting default colors and fonts

for Legends


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
