The suffix SDC identifies a table (spreadsheet) of the spreadsheet StarOffice Calc.
StarOffice was originally developed by the German company Star Division. The word processor StarWriter presented the basis of the package that first appeared for MS-DOS and subsequently for Windows. In 1999, Star Division was acquired by Sun Microsystems and ported StarOffice to various platforms. The components of OfficeSuite have been changed several times. In 2000, the source code was published by StarOffice, from which the open source project OpenOffice was created. Nevertheless, there was a commercial variant that offered additional support. From version 8 StarOffice supports the Open Document Standard.
In 2009 Sun was bought by Oracle, who discontinued the commercial version in 2011.
