This document provides an overview of spreadsheets and databases, highlighting their components and functionality. It discusses how spreadsheets manage financial data through cells organized in rows and columns, and describes databases as systems for storing and retrieving information organized into records and fields. Additionally, it covers various types of graphics software, including image manipulation and computer-aided design, used for creating and editing visual content.

1. SPREADSHEETS AND DATABASES

2. Spreadsheet basics
 A spreadsheet program helps you manage personal and
business finances. They are mathematical tables which show
figures in rows or columns.
 A cell can hold three types of data: text, numbers, and
formulae.

3.  Row Horizontal lines for data in a spreadsheet.
Identified with Numbers
 Column Vertical lines for data in a spreadsheet.
Identified with Letters
 Cell The individual intersections between rows and
columns. Labeled by the Row Number and Column
Letter.
 Active Cell The cell that is currently being edited.
Marked by a think black boarder around the cell.

4. Uses for databases
1.Prepare budgets
2.Maintain students grades
3.Prepare financial statements
4.Analyze numbers
5.Manage inventory
6.Make forecasts

5. PARTS OF A DATABASE
 A data base is a computerized record-keeping system. It is
a system designed to store information in a way that
makes it easy to locate later. A database software allows
users to store, organize, and manipulate information
including both text and numerical data.

6.  Each unit of information you create is called a record and each
record is made up of a collection of fields.
 There are different data types:
 Text: hold letters and numbers not used in calculations.
 Number: can only hold numbers used in calculations and reports.
 Memo: can store long texts
 Data/Time: a date or time or combination of both.
 Auto Number: assigns a number to each record.
 OLE Object: holds sounds and pictures.
 Yes/No: for alternative values like/true false, yes/no, on/off, etc.
 Hyperlink: adds a link to a website.

7.  Once you have added data to a set of records, indexes must be created to
help the database find specific records and classify records faster.
 Relational Databases:
 Two databases files can be related as long as they hold a piece of data in
common.
 Extracting information from a database is known as performing a query.

8. GRAPHICS AND DESIGN

9.  Types of graphics software
 Computer graphics are pictures created, changed or processed by
computers.
 There are two categories:
 Bitmapped Graphics represent images as bitmaps; they are stored as
pixels and can become a bit distorted when they are manipulated. The
density of dots, known as the resolution and expressed in dots per
inch, determine how sharp the image is.

10.  Vector Graphics represent images as mathematical formulae; so
they can be changed or scaled without losing quality.

11.  There are different types of graphics software
 Image manipulations programs: let you edit your favorite images.
 Painting and drawing programs: offer facilities for freehand drawing,
with a wide choice of pens and brushes, colors and patterns.

12.  Business graphics programs: let you
create pie charts, bar charts, and line
graphs of all kinds for slide shows and
reports.
 Computer aided-design (CAD): is used
by engineers and architects to design
everything from cars and planes to
buildings and furniture.

13.  There are different types
of graphics software
 Desktop publishing (DTP): is
based around a page layout
program, which lets you import
text from a word processor, and
images from scanners or
cameras; and arrange them all
on a page.
 Digital Art: is done with applets
that use mathematical formulae
to create fractals. A fractal is a
geometrical figure with special
properties.

14.  Computer animation:
uses graphics programs
to create or edit
moving pictures. Each
image in a sequence of
images is called a
frame.
 Geographic
Information Systems
(GIS): allow
cartographers to
create detailed maps.
