Apache's OpenOffice and The Document Foundation's LibreOffice

OpenOffice and LibreOffice share many of the same features and are excellent FREE alternatives to MicroSoft Office. They are available for Windows, OS X and Linux. These two office environments provide:
  • Writer - a document editing program comparable to MicroSoft's Word
  • Calc - a spreadsheet program comparable to MicroSoft's Excel
  • Impress - a presentation program comparable to MicroSoft's PowerPoint
  • Draw - a very useful program that supports vector drawing (reminiscent of MacDraw)
  • Base - a database program that supports ODBC, JDBC and other database files
  • Math - an equation editor for text documents.
OpenOffice and LibreOffice are both descendents of StarOffice, originally developed by StarDivision of Germany in the late 1990's. In 1999, StarDivision was acquired by Sun MicroSystems which released the first version of OpenOffice in 2002. In 2010, Sun was itself acquired by Oracle. A year later, Oracle donated the OpenOffice code to the Apache Software Foundation who continue to develop and maintain Apache OpenOffice.
Meanwhile, in 2010, following Oracle's takeover of Sun, The Document Foundation was established by a breakaway group of developers who released LibreOffice from the same codebase as OpenOffice. Today, in 2013, LibreOffice is part of most Linux distributions and considered by many to be superior to OpenOffice. Both, however, have ardent supporters and seem likely to continue for the foreseeable future.
OpenLogPlot reads data from a Calc spreadsheet and generates the log plot in Draw. OpenLogPlot has been developed using the Universal Network Objects (UNO) OpenOffice programming interface and the Java language.
