Tableau Desktop is a program used to produce graphics, reports and dashboards of any given data. The source can be in the form of a simple spreadsheet (Excel workbook), text files (.csv) or a database (SQL server or Oracle). Once information is entered into the program, it can display information in various graphical displays. Data can created in form of a chart, table, plot or a map. It also allows users to view, filter, sort, organize, calculate and summarize data. Data and results can be shared to any Tableau users or by copying the produced output into other programs like Microsoft office. Tableau Desktop works with Windows 7, XP, Vista, Server 2008/ 2003 and Microsoft Windows 8. A minimum system requirement of AMD Opteron or a Pentium 4 is a required with 250 MB of available disk space. Being a data visualization program, a 32-bit color depth is highly recommended for better graphic output.
