CRAC 4.1. Data integration "This section describes any activity related to data integration or data fusion. The data collection could be a combination of new and historical data, from external or internal sources, from a variety of collection instruments etc. For example the data collection could be enriched by information from official (governmental) or non-official sources. It could further include a description on: - Data pooling, with the aim of increasing the effective number of observations of some phenomena; - Mapping or record linkage routines, with the aim of linking different data sources that use different encoding schemas; - Prioritising, when two or more sources contain data for the same variable, with potentially different values. - Data anonymization, e.g. if identifiers such as name and address are stripped to help to protect confidentiality."
