 Microsoft access is a Database Management
System(DBMS).
 Microsoft access is just one part of Microsofts
overall data management product strategy.
 It stores data in its own format based on the access
jet database engine.
 It can also import are link directly to data stored in
other application and data bases.
 Access can also understand and use a wide variety
of other data formats , including many other data
base file structures.
 Software developers can use Microsoft access to
develop application software.

 Data base creation:
create your Ms-access database and
specify what kind of data you will be storing.
 Data input:
after your database is created, the data of
ever business day can be entered into the access data
base.
 Query: this is a fancy term to basically describe the
process of retrieving information from the data base.
 Report: Information from the database is organized in a
nice presentation that can be printed in an access
report.

MS-Access Is a data base and,more specifically, a
relational data base.
 Early versions of access cannot read accdb
extensions but ms access 2007 and later versions
can read and change earlier versions of access.
 An access desktop data base(.accdb or .mdb)is
the fully functional RDBMS.
 It provides all the data defination,data
manipulation and data control features that you
need to manage large volumes of data.
 When you build and application with an access
desktop database,access is the RDBMS.

 DATA DEFINATION:
In document or a spread sheet , you generally have
complete freedom to define the contents of the
documents or each cell in the spreadsheet.
 DATA MANIPULATION:
in a word processing document , you can include
tabular data and perform a limited set of functions
on the data in the document.
 DATA CONTROL:
Spread sheets and word processing documents are
great for solving single user problems , but they
are difficult to use when more than one person
needs to share the data.

 Ms access uses “objects” to help the user list and
organize information, as well as prepare specially
designed report.

 TABLE:
Table is an object that is. When you create new table
, access ask you to define fields which is also known
as column headings.
QUERY:
An object that provides a custom view of data from
one or more tables .
FORM: use forms to that your application extracts
from queries or table.
REPORT: report is an object in desktop databases
designed for

 To create a data base from a template , we first need to open
ms access and you will see the following screen .

TYPE OF DATA DESCRIPTION SIZE
SHORT TEXT TEXT OR
COMBINATION OF
TEXT AND NUMBERS
UPTO 255
CHARACTER
LONG TEXT LENGTHY TEXT UPTO 63,999
CHARACTER
NUMBER NUMERIC DATA USED
IN MATHEMATICAL
CALCULATION
1,2,4 OR 8 BYTES
DATE/TIME DATE AND TIME 8 BYTES
CURRENCY CURRENCY VALUES 8 BYTES
AUTO NUMBER A UNIQUE
SEQUENTUIAL
(INCREMENTED BY 1)
4 BYTES
YES/NO YES/NO VALUES 1 BIT

 A data sheet is a simple way to look at your
data in rows and columns without any special
formatting.
 Whenever you create a new web table ,
access automatically create two views that
you can start using immediately for data
entry.
 Let us add some data into your tables by
opening the access database we have
created.
 Select the views> data sheet view option in
the ribbon and add some data.
