DB2 Web Query for i 개요


Query/400: A history Lesson• Around since June, 1988• Lacks a graphical interface• Does not support output to PDF, HTML,

XML, or Excel• Does not support non-DB2 for i5/OS

databases• Does not support drill down from a

completed report• Is not a pure SQL interface• Does not use the SQL Query Engine

(SQE)– SQE was introduced with V5R2– CQE (Classic Query Engine) is used by

Query/400


System i Query/Reporting Environment

System i

DB2

Windows

ODBC/JDBC


Today’s Business Intelligence Requirements• Remove Dependency on IT for reporting purposes

– Ease IT backlog of reporting requests– Parameterized Reporting

• Reduce Report Maintenance• Empower End Users

• Client Independence– Web Based

• Reduce Software Maintenance• Multiple Viewing Options

– Dashboards/Scorecards– Spreadsheet Integration– Static Reports/Intelligent Bursting– Report Archival

• Operational or Data Warehouse– Real time or Historical Reporting

• Secure the Data– Avoid Data replication– Adhere to compliance requirements


IBM DB2 Web Query for i

• Base Program Product Includes:– i5/OS Web Reporting Server– Several Web Based authoring tools

• RA, GA, Power Painter– Query/400 (5722-QU1)

• Web Enable Query/400 Reports– BASE PRODUCT OFFERED AS NO CHARGE

UPGRADE FROM QU1• Does not include Software Maintenance

• Additional Features– Run Time User Enablement – Active Reports (Disconnected Analysis)– On Line Analytical Processing

• Requires Meta Data provided with Developer Workbench

– Developer Workbench• IT Tool for meta data http://www.ibm.com/systems/i/db2/webquery

• DB2 Web Query Report Broker– Automated Report Execution and Distribution

• DB2 Web Query SDK– Web Services to integrate reporting functions into

applications/portals


Upgrade into BASE Product from Query/400• The BASE product:

– Web enables Query/400 • Add additional functionality (compared to Query/400) to reports

– Link Reports by clicking on “hot spot”– Add Conditional Styling (“if revenue less than forecast, highlight in RED”)– Push data directly from DB2 into Spreadsheets– Over 100 charts and graphs– Boardroom quality PDF output– Access remote DB2 for i data sources

– Leverages the LATEST in DB2 for IBM i Query Optimization Technology• Better performance, better analysis tools• Many more functions available for query performance• Strategic optimizer


DB2 WQ Leverages Advanced DB2 Query Optimization

• SQL Query Engine (SQE)– Better Performance – up to 10x over older query engine– Self-learning query optimizer– Self-adapting query engine

• SQL Plan Cache– Real time analysis of Query performance– Index (traditional and EVI) advice (recommendations and wizards)

• Materialized Query Tables (MQTs)– Optimizer “aware” summary tables for extreme performance boost

• Non-SQL interfaces (Query/400, OPNQRYF, QQQQRY API) DO NOT LEVERAGE ANY OF THE ABOVE
