The Greek Social Data Bank does not only provide information on social data but it also compiles, documents and files data. For this purpose, the EKKE's Social Data and Indicators Archive (SDIA) was created. It is essentially a storage place for a significant number of data groups. The SDIA's administration lays with the documentation department of the Research Support Division. Data is imported into the SDIA and processed according to the Special Information Bank model. The Archive provides information regarding the encoding of the variables, thus contributing to the formation of relatively steady encoding systems for common use variables i.e. administrative divisions (countries, regions, prefectures etc) or the professions. The adoption of standard criteria and encoding systems by the research community contributes to rendering data comparable. Unfortunately this is a long and arduous process that has yet to be completed.

SDIA contains two data categories:

a) The micro data thesaurus which contains primary data collected in individual empirical research. This is not only EKKE research but data produced by other agencies as well.

b) The macro data thesaurus, which contains data produced by microdata analysing and processing, conducted by individual researchers at Greek Universities, research centres or other agencies, or produced by major data organizations such as EUROSTAT, OECD, major European social data archives and other organizations.

The Social Data and Indicators Archive was originally designed within the framework of EKKE's "Structural Development" and began to function as part of the Development of "Special Information Bank", funded by the "Kleisthenes" business program.
