WHAT IS A DATABASE?

As scientists we gather and record information not only for our own use but also for others to access and use. Our society is described as an information society. By 2015 it is predicted that the knowledge of the world will double every 76 days

What are some of the ways we store information and how it is accessed for us to use?

Write down a few ways we store and access information...

DEFINITION OF A DATABASE

“A database is a collection of information which is related and which can be organised and manipulated.”

(Science and technology K-6 pg 220)

INTRODUCTION TO DATABASES

Define the following terms relating to the database in your own words:

Record

Field

Data

File

A record is the information in the fields relating to one article. (one row of the table or one page of the form)

A database consists of a number of fields that contain the individual pieces of data. (eg for library catalogue, author, title, etc...)

The information within a field

A file stores all the records for related information

Page 5: DATABASES Southern Region CEO Friday 18 June 2010

Other definitions:

Each table of the database is a group of fields. (like headings in excel spreadsheet)

When creating a table, you also determine the characteristics of each field in the table. (ie. Whether it will contain text, a picture or a list of words)

Forms are for entering data into or viewing the fields of a table associated with the form.

Note query and report not covered here.

EVERYDAY EXAMPLES OF DATABASES

• A cell phone has an electronic database of names and numbers as does the address book in your e-mail program.

• A video store keeps a database of all the videos and another for all the customers.

• Most companies keep track of all payments to their employees medical aid, pension fund, unemployment insurance fund and also to do salary transfers.

• Your school also keeps a record of all your details and marks in a database.

COMPUTING SKILLS TEST

Information and Communication Technologies (ICT) have been integrated within the outcomes and content of the revised Years 7–10 syllabuses. A mapping of the ICT statements from the mandatory syllabuses is available on the Board’s website. Questions in the Computing Skills test will be drawn from these ICT statements.

The ICT skills that will be tested in the School Certificate Computing Skills test have been grouped into five skill areas:

•Computer operations•Word-processing•Spreadsheets and databases•Graphics and multimedia•Internet and email

7-10 Syllabus

4/5.16 gathering information from secondary sourcesa)use a range of sources, including databases, CD-ROMs and the internet, to access information

4/5.17 processing informationd) organise data using a variety of methods including diagrams, tables, spreadsheets and databases

4/5.18 presenting information e) use drawings, diagrams, graphs, tables, databases, spreadsheets and flow charts to show relationships and present information clearly and/or succinctly

AUSTRALIAN CURRICULUMInformation and communication technologies (ICT) are relevant to the teaching and learning in a large part of the Australian Curriculum: Science.This will include the use of the internet to research science concepts and applications as well as the use of digital learning objects such asanimations and simulations to enhance students’ understanding and engagement in science. The use of the internet and local networks willfacilitate a collaborative approach among students that models the methods of modern science. In practical investigations, ICT will aid students in tasks such as data collection and analysis through probeware, data logging and the use of spreadsheets. This enables students to use and analyse results efficiently, allowing for the development of valid conclusions, and also allows access to other potential areas for investigation.Simulations and modelling using ICT provide students with opportunities to test predictions which cannot be investigated through practicalexperiments in the classroom. ICT offers opportunities to provide a range of media for the communication and sharing of students’ ideas and understandings both within and beyond the classroom.

Observing and measuring – (spreadsheets)Collect and record data, making observations and measurements with accuracy appropriate to the task, using ICT where appropriate

Analysing results – (spreadsheets)Construct and use tables and graphs to represent and analyse data, including using ICT

Observing and measuring – (dataloggers)Collect data in a consistent, efficient, and ethical manner, including methods that use ICT

Analysing results – (spreadsheets)Represent and analyse data appropriately including using simple statistical methods and ICT

DEMONSTRATE BASIC DATABASE SKILLS TO CREATE, WORK WITH AND MODIFY FILES

From core Computing skills 2003 Board of Studies

Indicators•Identify basic database terminology (fields, records, files)

•Use basic search techniques to find information in an existing database

•Sort information according to desired criteria

•Add and delete records to an existing database

•Present data in form and list views

•Create a simple (flat file) database

DIFFERENTIATED SELF-DIRECTED LEARNING

Teachers new to data bases:

i)Work through Year 7 science dictionary to add terms

OR work through Year 8 Worksheet on atom

ii)Complete the Year 10 worksheet

iii)Start developing applications for their own teaching

Experienced users of databases:

i)Complete the Year 10 worksheet

ii)Teachers spend time investigating the resources available on the website

iii)Start developing applications for their own teaching
