Let’s Review



1. Database refers to any collection of data, or information, that is specially organized
for rapid search and retrieval by a computer.

2. Each item of data or column in a database is called a field. Each row in a database is
called a record.

3. Microsoft Access is a database management system (DBMS) used to store and
manage data.

4. A field’s data type determines what kind of data it can store.
5. Every field in a table has properties and these properties define the field’s

characteristics and behaviour.
6. A field is a way of organizing information by type. Whereas, A record is one unit of

information.
7. Forms in Access are like display cases in stores that make it easier to view or get the

items that you want.
8. Reports offer a way to view, format, and summarize the information in your Microsoft

Access database.

5.1. Getting Started with EDraw Max
EDraw Max is an extremely powerful all-in-one diagramming

tool that can serve all of your purposes. Whether you need to
draw flowcharts, fishbone diagrams, UML diagrams or design

floor plans, office layouts, you can find what you want in
EDraw Max.


5.2. EDraw Max Interface



EDraw user interface is similar to Microsoft Program interface, which can minimize the
learning curve. EDraw user interface includes 7 major menus: File, Home, Insert, Page

Layout, View, Symbols and Help. These menus are introduced in detail with illustrations
below. A menu’s background turns white after selected. Clicking another menu turns off

the menu selected before.

6.1. What is a Computer Program



A computer program is a series of instructions that tell a computer to perform an action.
Computer programs are a defined set of algorithms or processes that are completed in

order to achieve a task.
A program is created using a programming language, which allows a computer

programmer to write lines of code that the computer can understand.
Everything that a computer does is achieved using a program, whether that be browsing

the web with or processing a document using Microsoft Word.



6.2. What is Scratch


Scratch is a free visual programming language developed to help simplify the process
of creating and programming animations,

games, music, interactive stories and more.
With Scratch, you can program your own

interactive stories, games, and animations
and share your creations with others in the

online community.
Scratch is designed especially for ages 8 to

16 but is used by people of all ages. Millions
of people are creating Scratch projects in

a wide variety of settings, including homes,
schools, museums, libraries, and community

centres.
Scratch is a project of the Lifelong Kindergarten Group at the MIT Media Lab. It is provided

free of charge.
In Scratch, we write programs called Script. Each script controls an object called a Sprite.

The orange cat that you see when you start up Scratch is an example of a Sprite.

6.3. Scratch Interface


In Scratch, we write programs called script. Each script controls an object called a sprite.

The orange cat that you see when you start up Scratch is an example of a sprite. Here is
an example of what a script looks like.













































• The Stage is the background that our program runs on.

• The Sprite pane shows all of the sprites that are part of our program.
• The Block Palette contains the blocks that we can use to make our scripts. Each block

represents one instruction in our program.
We build our scripts by dragging blocks from the block palettes to the Script Area.

6.6. Script Area


To get our sprites to animate, move, or interact with one another on the stage, we need to

create one or more scripts for each sprite. If you click on a sprite from the list, the project
editor will show the existing stacks of blocks in the scripts area. To create a game, story, or

animation in Scratch, we stack blocks together to form a script that gives
instructions to the project sprites.

In the middle of the project editor screen, we have categories of blocks that are

grouped by the kinds of tasks they represent.
They are Motion, Looks, Sound, Pen, Data, Events, Control, Sensing, Operators, and

More Blocks.
We mix the blocks together to form our artwork. Each type of block is colour coded

so that we can easily identify them by their type in our scripts. Let’s Program
