Data standardization, data warehousing and data mining
The paper describes the process of standardization adopted in the last three years by the Center for Information about the Media (CIM) to unprove the quality and safety of data exchanges coming from audience surveys. The data are collected by field institutes and then controlled by CIM before being exploited by concession-holders or contributors mainly tor media-planning purposes. UsrConsult, the company in charge of the standardization, selected an original approach combining two specific tools: the ASN.l language to describe structures and the BER rules to encode the data. The paper describes these tools. Some practical examples ore also provided.
