Project Description:
Smart Source Rentals is widely recognized by customers, competitors, and industry organizations as the #1 computer rental and audio visual rental company in the United States. Smart Source Rentals offers a compelling combination of brand name equipment, top notch technical services, and competitive rates. The Project is to Develop Critical Reports for Financial and Sales department. Also intended to diagnose, Fix, test and maintain the legacy carry over reports which uses the logic that had been meeting the complexity of the mainframe period which never focused on the modern standards of Normalization or Dimensional approach for reporting.

Responsibilities:

  • Developed over 25 complex reports for Financial department.
  • Developed 50 medium complex reports for Sales Department.
  • Framework Manager modeling which involves multi-vendor data sources.
  • Fixed more than 200 Existing Reports which had underlying SQL errors
  • Dealt simultaneously with 5 Cognos servers each having 4 Packages which have at least 10 different folder structure which represent various Departments and Functional areas of the Business.
  • Severe diagnostics and successful query rework for at least 40 most complicated reports which failed in Cognos 10 due to the strict Relational SQL rule implementation from the previous versions of Cognos.
  • Performance boost strategy work on Hundreds of Reports which had logic embedded from legacy systems point of view.
  • Performance intended work on every possible ways which involves but not limited to different database processing on each query levels, auto group and summary, Union preserve, package routing, filter combinations.
  • Accurate reporting for the Future Booked Business and Reservations.
  • Cognos SQL – Relational SQL to check the accuracy correction for the report logic due to the non availability of a reporting database.
  • MS Excel based manipulations from Application point of view and Cognos Query as well as Reports generation , for Testing purpose.
  • Security implementation.
  • Report performance boosting strategy development and implementation.
  • Different burst reports for ease of access, security and less development time
  • Work with Business users to gather requirement and take strategic steps.

  • Challenging Exposures:
  • Dealt successfully with a database structure which did not implement at least 3rd normalization or Dimensional standards for Reporting.
  • Reporting out of Database structures and Models logic that carry forward from the mainframe days.
  • Cognos Reporting from a database that possess many of the tables which does not even have a primary key or foreign key implemented or in other words exists without referential integrity.

  • Complexities:
  • Non Reporting database structures forces to develop a minimum of thirty reports with an average of fifteen queries each have its own filters which numbered at a range of 8 to 25 filters.
  • Due to the non-standard nature of Database structures and implementation, Report Queries had to be fortified with tons of filters which includes several combinations of ‘OR’ and ‘AND’ rules/Logic.
  • Several areas of Business is conducted with manual entries which leads to the report development with a heavy support from ‘UNION’ logic implementation between base queries.
  • Forced OUTER JOINs between several queries due to the branched deviations in the total Business Process which leads to complex database schemas and duplicated data existence.
  • Volatile nature of the Business and Data.

Cognos 10, Framework Manager, Rental Results Application, Enterprise Linux, Windows server 2003, Windows server 2008, MS SQL server 2008 R2, MS Excel 2010, Open Edge Progress Database.
