Verizon Communications Inc. was formed in 2000 with the merger of Bell Atlantic Corp. and GTE Corp., and the company continued to grow through acquisitions all of which produced difficulties in reconciling data across markets and regions. Verizon recognized the need for universal access to a central data repository to expedite data queries and provide valuable customer insight.
Verizon’s initiative began with an enterprise data warehouse from Teradata, which served to aggregate metrics across hierarchies. Verizon sought insight through customer and product data to successfully promote its offerings.
In 2003, Verizon developed Performance Assurance Reporting Suite (PARS), a relational online analytical processing (ROLAP) application that serves as a scalable common point of access and operates on top of the company’s active enterprise data warehouse environment from Teradata in the same high-speed server. By building its own application, Verizon:
- Saved approximately $2 million in resources over a four-year period
- Saved $1 million in licensing fees and maintenance
- Reduced preparation time by 90 percent
