Common Features of Application Software.

You control and interact with a program using a user interface. A graphical user interface (GUI) uses icons selected by a mouse-controller pointer. A window contains a document, program, or message. Most software programs, including Microsoft Office 2003, also have : -

·        Menus – present commands listed on the menu bar.
·        Dialog box – provides additional information or request user input.

Microsoft Office 2010 uses and interface introduced with Microsoft Office 2007 which includes:-
  1. Ribbons replace menus and tool
  2. Tabs divided ribbons into major activity areas organized into groups. Contextual Tabs automatically appear when needed
  3. Galleries display graphic representations of alternatives.


Some applications support speech recognition by allowing voice input.

SPREADSHEETS



Spreadsheets programs are used to organized, analyze and graph numeric data.

Features


Principal spreadsheets features include the following:-
  • Workbook files consists of one or more related worksheets.
  •  Worksheets, also known as spreadsheets or sheets , are rectangular grids of rows and columns. Rows are identified by numbers, column by letters.
  •  Cells are formed by the intersection of a row and column; used to hold text and numeric entries.
  • Text entries (labels) provide structure and numeric entries can be numbers or formulas.
  • Formulas are instructions for calculations. Functions are prewritten formulas.
  • Range is a series of cells.
  •  Analytical graphs (charts) represent data visually.
  • Recalculation occurs whenever a value changes in one cell that affects another cell(s)
  • What-if analysis is the process of observing the effect of changing one or more values.

DATABASE MANAGEMENT SYSTEMS 





A database is a collection a related data. A database management system (DBMS) , also known as a database manager, structures a database and provides tools for manipulating data.


Features
  1. Principal database management system features include the following:-
  2. Relational database organizes data into related tables.
  3. Tables have rows (records) and columns (fields).
  4. Sort is a tool to rearrange records.
  5. Filter is a tool to display only those records meeting specified conditions.
