Drawing or diagram created by Apache OpenOffice Draw, a vector graphics drawing program included with Apache OpenOffice and Oracle's Open Office; typically contains drawn vector objects but also supports raster graphics.
SDA files can be used for storing organizational charts, flowcharts, network diagrams, and other types of drawings.
NOTE: SDA files were used by StarOffice through version 5. StarOffice 6 adopted the .SXD format, but Apache OpenOffice and Open Office now both use .ODG files for drawings. Apache OpenOffice was previously known as OpenOffice.org.
