Indeed, the developed system has a GUI (Graphical User Interface) that on the one hand permits to build record linkage work-flows with a good flexibility. The RELAIS project aims to provide record linkage techniques easily accessible to not-expert users. It has been implemented using a relational database architecture, in particular it is based on a MySQL environment that is also in line with the open source philosophy of the RELAIS project.The choice of Java and R is also in line with the open source philosophy of the RELAIS project. This choice depends on our belief that a record linkage process is composed of techniques for manipulating data, for which Java is more appropriate, and of calculation-oriented techniques for which R is a preferable choice.

It is released under the EUPL license (European Union Public License). It has been developed as an open source project, so several solutions already available for record linkage in the scientific community can be easily re-used.It is designed and developed to allow the combination of different techniques for each of the record linkage phases, so that the resulting work-flow is actually built on the basis of application and data specific requirements.
RELAIS is a toolkit relying on these ideas. This is why it is reasonable to dynamically select the most appropriate technique for each phase and to combine the selected techniques for building a record linkage work-flow of a given application. Moreover, in some applications, there is no evidence to prefer a given method to others or of the fact that different choices, at some linkage stage, could bring to the same results. We believe that the choice of the most appropriate technique not only depends on the practitioner’s skill but, most of all, it is application specific. In fact, record linkage can be seen as a complex process consisting of several phases involving different knowledge areas moreover, several different techniques can be adopted for each phase. In statistics, record linkage is needed for several applications, including: enriching the information stored in different data-sets de-duplicating data-sets improving the data quality of a source measuring a population amount by capture-recapture method checking the confidentiality of public-use micro data. The purpose of record linkage is to identify the same real world entity that can be differently represented in data sources, even if unique identifiers are not available or are affected by errors. RELAIS (REcord Linkage At IStat) is a toolkit providing a set of techniques for dealing with record linkage projects.
