6 Oracle Designer Oracle s original CASE tool for - capturing & presenting business requirements - system analysis - software design - automatic code generation, and - business process re-engineering Often used for modeling only Timeline - introduced last update 2010 dropped in favour of SQL Developer Data Modeler 6

7 Oracle Warehouse Builder Oracle s original DWH building tool for - modelling data transformations - modeling complex data flows - modeling DWH structures - implemented ELT approach Often used for flow modeling only Timeline - introduced last release 2013 dropped in favour of Oracle Data Integrator 7

8 Oracle Warehouse Builder - Modeling Support for DWH relevant objects - Tables - Views - Materialized Views - Sequences - Constraints - Indexes Missing OLTP objects, e.g. Triggers Mixed feelings - all meta data in one place - deployment functionality limited Good & cheap solution for Oracle DWH environments only 8

10 SQL*Developer Data Modeler - Basics Introduced 2009 Oracle s current DB modeling & design tool Heterogenous Allows modeling of - logical models - relational models - physical models - domains - data types - data flows, and - business information - 10

11 SQL*Developer Data Modeler - Advanced Re-Engineering Synchronization Configuration Management Search Reporting DDL generation Get started. Read Heli s book! 11

12 SDDM - Assessment Huge number of features Comparable to best-in-class competition License cost free! But what about the usual modeling tool disadvantages: - most are entirely GUI driven - require lots of pointing & clicking - mass changes are tedious - standard checking & enforcing id hard SDDM s automation kicks in 12

13 Agenda Introduction History & Competition SQL Developer Data Modeler Modeling Automation Conclusions 13

14 Oracle Warehouse Builder - Automation OMB*Plus Tcl scripting API Real API usable without OWB client Tcl macros for structure - creation - modification - configuration Requires skills regarding Tcl Documentation is - mediocre at best - available discontinued as OWB is in general 14

15 SDDM Automation - Basics Different pre-seeded script libraries - design rules - custom rules - DDL transformation - libraries - transformations Multiple scripting engines Adding engines is easy Great for - applying mass changes - standard checks & enforcement - customizing DDL generation 15

16 SDDM Automation - Where to Start? Look into provided scripts Read Jeff Smith s Blog Practice Oracle by Example Try to make sense of the API documentation Choose your scripting language of choice Install chosen language Start to experiment Automate the sh** out of your design challenges 16

17 SDDM Automation - The sumit Way Groovy rules Highly standardized modeling paradigm -> Data Vault Store design configuration meta data in tables Script SDDM for - JDBC reads of design data - creation of structures - setting of properties - building of sub-views Use library for agile DWH model development 17

20 Conclusions Sql*Developer Data Modeler is a full fledged enterprise modeling tool Advanced features & zero price point make it a no brainer to use SDDM The real kicker are SDDM s automation features SDDM s automation allows to - raise productivity tremendously - raise model quality significantly - successfully combine enterprise quality data modeling with agile SW development But: in absence of documentation, it takes some exploration to get the desired result Go for modeling automation now Call sumit for a jump start 20
