What is a database? A database is any
collection of data that is organized for quick retrieval.
Databases can be computer based or paper based

Types of Databases
There are two main types of databases:
Flat Database
Relational Database

Flat Database Is a simple database model, where all the
information is stored in a plain text file, one database record per line.

Relational Database All information in the
database is stored in related tables each consisting of rows and columns.
The tables can be linked to each other in the database by the use of values common to more than one table.

What is MS Access 2010? Access is a powerful database
management program that can be used for:
storing,
organizing,
retrieving, and
reporting (summarize and print) information.

What can we do with a database? Find the related data
Analyze, manage, manipulate and retrieve the data
Display the information as a chart, graph or Web page
Print or publish uses friendly reports
Automate auto repetitive tasks
Export the data to other programs such as MS Excel and MS Word, and
Protect the data from errors

Access or Excel? An Excel spreadsheet is a good choice to do calculations,
analysis such and graphing.
But Excel is relatively poor at handling lots of different sets of related data.
An Access database is used for storing lots of data in a format that can be searched and summarized on reports.
It is ideal for setting up and managing sets of related data, but is relatively poor at the mathematical analysis whereas Excel is good at.

Microsoft Access Database Objects
A database usually consists of several objects.
An Access database might contain up to seven different database object types.

Microsoft Access Database Objects
Tables
Queries
Forms
Reports
Pages
Macros
Modules

Tables Tables store a
database’s data in rows (records) and columns (fields).
A database must always contain at least one table where it can store the information.

Tables
In a database table:
Rows are called Records
Columns are called Fields

Queries
Queries ask a question of data stored in a table.

Forms
Forms are custom screen that provide an easy way to enter, view and modify the data in a table or query.

Reports Reports present
data from a table or query in a printed format

Pages A special type of Web
pages designed for viewing and working with Access data from an Intranet or Internet.
It is the only external object of a MS Access Database.

Macros Macros help us to
perform routine tasks by automating them in a single command.

Modules
Are like Macros, modules automate tasks but by using a built-in programming language called Visual Basic for Applications or VBA.
They are much more powerful and complex than macros.
