The document discusses several capabilities of Oracle Database 11g that can help support data warehouse operations and address common challenges. It provides use cases and examples for features like partitioning, advanced compression, Oracle Database JVM, advanced queueing, Oracle Streams, and edition-based redefinition to help with tasks like data retention, tracking ETL processes, integrating proprietary file formats, asynchronous updates, and data warehouse modernization.

1. Leveraging and Enriching the capabilities of Oracle Database 11g Dylan Kucera – _dylan_kucera@otpp.com_ Director – Data Architecture Ontario Teachers’ Pension Plan Collaborate 2011 – Session 239 Wed April 13, 2011 – 8am – 9am

5. Partitioning Use Case – Data Retention

9. Use Case – Advanced Compression

10. Use Case – Advanced Compression Connected to Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 Connected as OPS$KUCERAD SQL> SELECT COUNT(ETL_ID), ROUND(AVG(LENGTH_)), TO_CHAR(SUM(LENGTH_), 'FM999,999,999,999') FROM ETL.ETL_ARCHIVE; COUNT(ETL_ID) ROUND(AVG(LENGTH_)) TO_CHAR(SUM(LENGTH_),'FM999,99 ------------- ------------------- ------------------------------ 216413 269977 58,426,579,616 SQL> CREATE TABLE ETL.ETL_ARCHIVE ( ETL_ID NUMBER, DATE_ DATE, LENGTH NUMBER FILE_ BLOB) LOB(FILE_) STORE AS SECUREFILE ( COMPRESS CACHE ) Back to Data Retention: Interval Partition!!

25. Data Warehouse Centralization – Heterogeneous Oracle Streams Oracle Streams ETL

26. Heterogeneous Streams – General Architecture Diagram Adapted from “Oracle Database 11g: Oracle Streams Replication, An Oracle White Paper, July 2007”

27. Heterogeneous Streams – Before inserts to Captured Oracle table

28. Heterogeneous Streams – Insert some rows into Captured Oracle table SQL> INSERT INTO PLAY.NHL_PLAYER_STAT (DATE_, TEAM, SWEATER_NO, NAME_, BIRTH_DATE, POINTS, FACE_OFF_PCT) 2 VALUES ('2010-08-31', 'VAN', 33, 'Henrik Sedin', '1980-09-26', 112, 49.5); 1 row inserted SQL> INSERT INTO PLAY.NHL_PLAYER_STAT (DATE_, TEAM, SWEATER_NO, NAME_, BIRTH_DATE, POINTS, FACE_OFF_PCT) 2 VALUES ('2010-08-31', 'PIT', 87, 'Sidney Crosby', '1987-08-07', 109, 55.9); 1 row inserted SQL> INSERT INTO PLAY.NHL_PLAYER_STAT (DATE_, TEAM, SWEATER_NO, NAME_, BIRTH_DATE, POINTS, FACE_OFF_PCT) 2 VALUES ('2010-08-31', 'WSH', 8, 'Alex Ovechkin', '1985-09-17', 109, 45.4); 1 row inserted SQL> INSERT INTO PLAY.NHL_PLAYER_STAT (DATE_, TEAM, SWEATER_NO, NAME_, BIRTH_DATE, POINTS, FACE_OFF_PCT) 2 VALUES ('2010-08-31', 'SJS', 19, 'Joe Thornton', '1979-07-02', 89, 53.9); 1 row inserted SQL> INSERT INTO PLAY.NHL_PLAYER_STAT (DATE_, TEAM, SWEATER_NO, NAME_, BIRTH_DATE, POINTS, FACE_OFF_PCT) 2 VALUES ('2010-08-31', 'OTT', 11, 'Daniel Alfredsson', '1972-12-11', 71, 35.0); 1 row inserted SQL> INSERT INTO PLAY.NHL_PLAYER_STAT (DATE_, TEAM, SWEATER_NO, NAME_, BIRTH_DATE, POINTS, FACE_OFF_PCT) 2 VALUES ('2010-08-31', 'CGY', 12, 'Jarome Iginla', '1977-07-01', 69, 47.0 ); 1 row inserted SQL> INSERT INTO PLAY.NHL_PLAYER_STAT (DATE_, TEAM, SWEATER_NO, NAME_, BIRTH_DATE, POINTS, FACE_OFF_PCT) 2 VALUES ('2010-08-31', 'TOR', 15, 'Tomas Kaberle', '1978-03-02', 49, NULL); 1 row inserted SQL> COMMIT; Commit complete

29. Heterogeneous Streams – After inserts to Captured Oracle table
