OpenOffice.org Calc

CALC is the spreadsheet program you've always wanted. Newcomers find it intuitive and easy to learn; professional data miners and number crunchers will appreciate the comprehensive range of advanced functions.

 Advanced DataPilot technology makes it easy to pull in raw data from corporate databases; cross-tabulate, summarise, and convert it into meaningful information.

Natural language formulas let you create formulas using words (e.g. "sales - costs").

The Intelligent Sum Button inserts a sum function or a subtotal automatically, depending on context.

Wizards guides you through choosing and using a comprehensive range of advanced spreadsheet functions, or download templates from our Extensions repository for ready-made spreadsheet solutions.

Styles and Formatting makes it easy to apply flexible cell formatting options, including freely rotating contents, templates, backgrounds, borders, and many more. You can be your own spreadsheet expert thanks to templates with built-in functions, allowing you to concentrate on your real work.

Scenario Manager allows "what if ..." analysis at the touch of a button - e.g. compare profitability for high / medium / low sales forecasts.

CALC's solver component allows solving optimization problems where the optimum value of a particular spreadsheet cell has to be calculated based on constraints provided in other cells.

Encourage collaborative working on spreadsheets with CALC's multiple users support. By sharing a spreadsheet other users can easily add their data to the spreadsheet. The spreadsheet owner can then easily integrate the new data with a few clicks. This collaboration feature helps avoid editing conflicts.

Save your spreadsheets in OpenDocument format, the new international standard for office documents. This XML based format means you're not tied in to CALC. You can access your spreadsheets from any OpenDocument compliant software.

Of course, you are free to use your old Microsoft Excel spreadsheets, or save your work in Excel format for sending to people who are still locked into Microsoft products. If all they want to see is your results, then use Portable Document Format (.pdf) - no need to buy any extra software. Since version 3.0, CALC has been able to read .xlsx files created with Microsoft Office 2007 or Microsoft Office 2008 for Mac OS X.

DBF Viewer 2000 is a powerful, compact and easy-to-use viewer and editor for DBF files (Clipper, dBase, FoxBase, Foxpro, Visual Foxpro, Visual DBase, VO, DB2K, etc.) With DBF Viewer 2000, you can view, edit, sort, query by example, delete duplicates, create, print database tables and export the data from them to a variety of formats (DBF, TXT, CSV, Excel, HTML, XML, PRG, SQL, RTF) without using any packages. Unlike other similar programs, DBF Viewer 2000 is fast! The program also allows viewing and editing of memo fields in dBase III, dBase IV, FoxPro, VFP and DB2K formats. DBF Viewer 2000 does not require external drivers for connection to databases (ODBC, BDE)..

dBASE

dBase was the first widely used database management system (DBMS) for microcomputers, published by Ashton-Tate for CP/M, and later on the Apple II, Apple Macintosh, UNIX, VMS, and IBM PC under DOS where it became one of the best-selling software titles for a number of years. dBase was slow to transition successfully to Microsoft Windows and gradually lost market share to competitors such as Paradox, Clipper, FoxPro, and Microsoft Access. dBase was sold to Borland in 1991, which sold the rights to the product line in 1999 to the newly-formed dBase Inc. In 2004, dBase Inc. changed its name to dataBased Intelligence, Inc.

Starting in the mid 1980s many other companies produced their own dialects or variations on the product and language. These included FoxPro (now Visual FoxPro), Arago, Force, dbFast, dbXL, Quicksilver, Clipper, Xbase++, FlagShip, Recital's Terminal Developer, and Harbour/XHarbour. Together these are informally referred to as xBase. dBase's underlying file format, the .dbf file, is widely used in many other applications needing a simple format to store structured data.

dBase has evolved into a modern object oriented language that runs on 32 bit Windows. It can be used to build a wide variety of applications including web apps hosted on a Windows server, Windows rich client applications, and middleware applications. dBase can access most modern database engines via ODBC drivers.

dBase features an IDE with a Command Window and Navigator, a just in time compiler, a preprocessor, a virtual machine interpreter, a linker for creating dBase application .exe's, a freely available runtime engine, and numerous two-way GUI design tools including a Form Designer, Report Designer, Menu Designer, Label Designer, Datamodule Designer, SQL Query Designer, and Table Designer. Two-way Tools refers to the ability to switch back and forth between using a GUI design tool and the Source Code Editor. Other tools include a Source Code Editor, a Project Manager that simplifies building and deploying a dBase application, and an integrated Debugger. dBase features structured exception handling and has many built-in classes that can be subclassed via single inheritance. There are visual classes, data classes, and many other supporting classes. Visual classes include Form, SubForm, Notebook, Container, Entryfield, RadioButton, SpinBox, ComboBox, ListBox, PushButton, Image, Grid, ScrollBar, ActiveX, Report, ReportViewer, Text, TextLabel and many others. Database classes include Session, Database, Query, Rowset, Field, StoredProc and Datamodule classes. Other classes include File, String, Math, Array, Date, Exception, Object and others. dBase objects can be dynamically subclassed by adding new properties to them at runtime.

dBASE Plus is a rapid application development toolset that includes a modern object oriented programming language (dBL) that runs on 32 bit versions of Microsoft Windows. It can be used to build a wide variety of applications including web applications, rich client applications, middleware applications, and server based applications. dBASE Plus has robust database access support and can access most modern database engines including Oracle, SQL Server, Sybase, MySQL, Informix, DB2, InterBase, FireBird, Pervasive SQL, Microsoft Access and other databases that can be accessed via ODBC. In addition dBASE Plus supports access to its native .dbf tables (levels 3, 4, 5, and 7) as well as Paradox (.db) tables, FoxPro and Visual FoxPro tables.
