1, The full form of SDDS is Special Data Dissemination Standard. It’s used on Associations & Organizations ,International Orgaizations in Worldwide

Special Data Dissemination Standard (SDDS) was established by the International Monetary Fund (IMF) to guide members that have, or that might seek, access to international capital markets in the provision of their economic and financial data to the public. Data dissemination standards enhance the availability of timely and comprehensive statistics, which contributes to sound macroeconomic policies and the efficient functioning of financial markets.

The SDDS is a global benchmark for disseminating macroeconomic statistics to the public. SDDS subscription indicates that a country meets the test of “good statistical citizenship.” The SDDS Guide for Subscribers and Users contains details on commitments undertaken by a subscriber, and is available on the DSBB. Countries that subscribe to the SDDS agree to follow good practices in four areas: the coverage, periodicity, and timeliness of data; public access to those data; data integrity; and data quality.

2, The full form of SDDS is Sony Dynamic Digital Sound. It’s used on Technology ,General in Worldwide

Sony Dynamic Digital Sound (Japanese: ソニーダイナミックデジタルサウンド, Hepburn: Sonī Dainamikku Dejitaru Saundo, SDDS) is a cinema sound system developed by Sony, from which compressed digital sound information is recorded on both outer edges of the 35 mm film release print. The system supports up to eight independent channels of sound: five front channels, two surround channels and a single sub-bass channel. The eight channel arrangement is similar to large format film magnetic sound formats like Cinerama and Cinemiracle. The five front channels are useful for very large cinema auditoriums where the angular distance between center and left/right channels may be considerable. SDDS decoders provide the ability to downmix to fewer channels if required.

The School District Demographics System (SDDS) is a Web-based resource operated by the National Center for Education Statistics (NCES) of the U.S. Department of Education. SDDS enables access to school district demographic and related geographic data that is not available in any other form. SDDS was initially developed to provide access to the 2000 School District Special Tabulation (STP2) and corresponding 1990 Census SDST. SDDS has evolved as more recent data have become available through the American Community Survey School District Special Tabulations. SDDS includes only summary data tabulated for geographic areas from public use data files. SDDS includes no data for/about individuals.
