ntroduction to Java

- Java is an object oriented programming language

-with a built in application programming interface

( )API that can handle graphics and user interfaces

and that can be used to create applications or

. ' ,applets Because of its rich set of API s similar to

,Macintosh and Windows and its platform

,independence Java can also be thought of as a

.platform in itself Java also has standard libraries

.for doing mathematics

Much of the syntax of Java is the same as C and

++.C One major difference is that Java does not

. ,have pointers However the biggest difference is

.that you must write object oriented code in Java

Procedural pieces of code can only be embedded

.in objects In the following we assume that the

reader has some familiarity with a programming

. ,language In particular some familiarity with the

/ ++ .syntax of C C is useful

,In Java we distinguish between applications which

are programs that perform the same functions as

,those written in other programming languages and

,applets which are programs that can be

embedded in a Web page and accessed over the



.Internet Our initial focus will be on writing

. ,applications When a program is compiled a byte

code is produced that can be read and executed

.by any platform that can run Java

,Compared to other programming languages Java is

.most similar to C However although Java shares

' , .much of C s syntax it is not C Knowing how to

, , ++,program in C or better yet C will certainly help

, 'you to learn Java more quickly but you don t need

. ++to know C to learn Java Unlike C Java is not a

. 'superset of C A Java compiler won t compile C

,code and most large C programs need to be

changed substantially before they can become

. Java programs

'What s most special about Java in relation to other

programming languages is that it lets you write

special programs called applets that can be

downloaded from the Internet and played safely

.within a web browser Traditional computer

programs have far too much access to your

- .system to be downloaded and executed willy nilly

Although you generally trust the maintainers of various ftp archives and bulletin boards to do

basic virus checking and not to post destructive

, .software a lot still slips through the cracks Even

more dangerous software would be promulgated if



any web page you visited could run programs on

.your system You have no way of checking these

- -programs for bugs or for out and out malicious

.behavior before downloading and running them

Java solves this problem by severely restricting

.what an applet can do A Java applet cannot write

.to your hard disk without your permission It

cannot write to arbitrary addresses in memory and

.thereby introduce a virus into your computer It

should not crash your system

eature of Java

Platform. .Independent

- - - ( The concept of Write once run anywhere known

)as the Platform independent is one of the

important key feature of java language that makes

. java as the most powerful language Not even a

single language is idle to this feature but java is

.more closer to this feature The programs written

on one platform can run on any platform provided

.the platform must have the JVM

Simple

There are various features that makes the java as

.a simple language Programs are easy to write and

debug because java does not use the pointers



.explicitly It is much harder to write the java

programs that can crash the system but we can

.not say about the other programming languages

Java provides the bug free system due to the .strong memory management It also has the

automatic memory allocation and deallocation

.system

Object. .Oriented

, To be an Object Oriented language any language

.must follow at least the four characteristics

Inheritance :

It is the process of creating the new classes and

using the behavior of the existing classes by

extending them just to

reuse the existing code and adding the additional features as

.needed

Encapsulation:

It is the mechanism of combining the

.information and providing the abstraction

:olymorphism

,As the name suggest one name multiple form

Polymorphism is the way of providing the different



functionality by the

functions having

the same name based on the signatures of the

.methods

ynamic binding:

'Sometimes we don t have the knowledge of

objects about their specific types while writing our

.code It is the way

of providing the maximum functionality to a .program about the specific type at runtime

, ++As the languages like Objective C C fulfills the

above four characteristics yet they are not fully

object oriented languages because they are

.structured as well as object oriented languages

,But in case of java it is a fully Object Oriented language because object is at the outer most level

. ,of data structure in java No stand alone methods

, .constants and variables are there in java

Everything in java is object even the primitive

data types can also be converted into object by

.using the wrapper class

Robust

Java has the strong memory allocation and

.automatic garbage collection mechanism It

provides the powerful exception handling and type



checking mechanism as compare to other

.programming languages Compiler checks the

program whether there any error and interpreter

checks any run time error and makes the system .secure from crash All of the above features

.makes the java language robust

Distributed

The widely used protocols like HTTP and FTP are

.developed in java Internet programmers can call

functions on these protocols and can get access

the files from any remote machine on the internet

.rather than writing codes on their local system

Portable

- - - The feature Write once run anywhere makes the

java language portable provided that the system

.must have interpreter for the JVM Java also have

the standard data size irrespective of operating

.system or the processor These features makes the

. java as a portable language

Dynamic

While executing the java program the user can

get the required files dynamically from a local

drive or from a computer thousands of miles away

.from the user just by connecting with the Internet



Secure

. Java does not use memory pointers explicitly All

the programs in java are run under an area known

.as the sand box Security manager determines the accessibility options of a class like reading and

.writing a file to the local disk Java uses the public

key encryption system to allow the java

applications to transmit over the internet in the

.secure encrypted form The bytecode Verifier

.checks the classes after loading

Performance

, Java uses native code usage and lightweight

process called .threads In the beginning

interpretation of bytecode resulted the

performance slow but the advance version of JVM

uses the adaptive and just in time compilation .technique that improves the performance

Multithreaded

As we all know several features of Java like

, , , ;Secure Robust Portable dynamic etc you will be

more delighted to know another feature of Java

.which is Multithreaded Java is also a Multithreaded programming

.language Multithreading means a single program

having different threads executing independently

.at the same time Multiple threads execute



instructions according to the program code in a

.process or a program Multithreading works the

similar way as multiple processes run on one

.computer Multithreading programming is a very interesting

.concept in Java In multithreaded programs not

even a single thread disturbs the execution of

.other thread Threads are obtained from the pool

of available ready to run threads and they run on

.the system CPUs This is how Multithreading works

in Java which you will soon come to know in

.details in later chapters

Interpreted

We all know that Java is an interpreted language

. ,as well With an interpreted language such as Java

.programs run directly from the source code The interpreter program reads the source code

.and translates it on the fly into computations

, Thus Java as an interpreted language depends on

.an interpreter program

The versatility of being platform independent

.makes Java to outshine from other languages The

source code to be written and distributed is

.platform independent

Another advantage of Java as an interpreted

.language is its error debugging quality Due to this



.any error occurring in the program gets traced

. This is how it is different to work with Java

/rchitecture Neutral

, The term architectural neutral seems to be weird

but yes Java is an architectural neutral language

.as well The growing popularity of networks makes

.developers think distributed In the world of

network it is essential that the applications must

be able to migrate easily to different computer

.systems Not only to computer systems but to a

wide variety of hardware architecture and

.Operating system architectures as well The Java

compiler does this by generating byte code

,instructions to be easily interpreted on any

machine and to be easily translated into native

.machine code on the fly The compiler generates -an architecture neutral object file format to enable

a Java application to execute anywhere on the

network and then the compiled code is executed

,on many processors given the presence of the

. Java runtime system Hence Java was designed to

.support applications on network This feature of

. Java has thrived the programming language



ntroduction to Microsoft

Access

,Microsoft Office Access previously known as

,Microsoft Access is a relational database

management system from Microsoft that combines

the relational Microsoft Jet Database Engine with a

graphical user interface and software development

. 2007tools It is a member of the Microsoft Office

.system

Access can use data / ,stored in Access Jet Microsoft

SQL Server, Oracle, or any ODBC-compliant data

(container including MySQL and PostgreSQL).

Skilled software developers and data architects

use it to develop application software. Relatively

unskilled programmers -and non programmer

" "power users can use it to build simple

.applications It supports some -object oriented

-techniques but falls short of being a fully object

.oriented development tool

Access was also the name of a communications

,program from Microsoft meant to compete with

ProComm .and other programs This proved a

.failure and was dropped [1] Years later Microsoft

.reused the name for its database software

A database is a collection of information relegated

,to a particular subject or purpose such as tracking

customer order or maintaining a music collection

,or novels written by authors in a alphabetic order .pin code of cities in alphabetic order etc Using

,Microsoft access you can manage all your

information from a single database file within the

.forms

3. Find and retrieve the data you want by using

.using reports

History

1.0 1992,Access version was released in November

1993 1.1followed in May of by an Access release

to improve compatibility with other Microsoft

.products

Microsoft specified the minimum operating system

2.0 3.0 4for Version as Microsoft Windows v with



. 6MB of RAM MB RAM was recommended along

8with a minimum of MB of available hard disk

(14 ).space MB hard disk space recommended The

1.44 .product was shipped on seven MB diskettes 1993 . The manual shows a copyright date

The software worked well with very large records

sets but testing showed some circumstances

. ,caused data corruption For example file sizes

700 (over MB were problematic note that most

700hard disks were smaller than MB at the time

).this was in wide use The Getting Started manual

warns about a number of circumstances where

obsolete device drivers or incorrect configurations

.can cause data loss

' ;Access s initial codename was Cirrus the forms

.engine was called Ruby This was before Visual

Basic - Bill Gates saw the prototypes and decided

that the BASIC -language component should be co

,developed as a separate expandable application a

.project called Thunder The two projects were

developed separately as the underlying forms

;engines were incompatible with each other ,however these were merged together again after

VBA.

,Access is used by small businesses within

,departments of large corporations and by hobby

programmers to create ad hoc customized desktop

systems for handling the creation and .manipulation of data Access can be used as a

database for basic web based applications hosted

'on Microsoft s Internet Information Services and

utilizing Microsoft Active Server Pages ASP.

Some professional application developers use

Access for rapid application development,

especially for the creation of prototypes and

-standalone applications that serve as tools for on

- .the road salesmen Access does not scale well if

,data access is via a network so applications that

are used by more than a handful of people tend

to rely on -Client Server based solutions.[citation needed] , " " (However an Access front end the

, ,forms reports queries and VB )code can be used

against a host of database backends, including JET

( - ,file based database engine used in Access by

), , ,default Microsoft SQL Server Oracle and any

other ODBC- .compliant product

compatibility with SQL ( )structured query language

—queries may be viewed and edited as SQL

,statements and SQL statements can be used

directly in Macros and VBA Modules to manipulate .Access tables Users may mix and use both VBA

" "and Macros for programming forms and logic

- .and offers object oriented possibilities

MSDE ( ) 2000,Microsoft SQL Server Desktop Engine

- 2000,a mini version of Microsoft SQL Server is

included with the developer edition of Office XP

and may be used with Access as an alternative to

the Jet Database Engine.

-Unlike a server based RDBMS ,such as SQL Server

Access does not implement database triggers or

stored procedures. However Access provides a rich

-programming environment through its event driven

.forms and reports which utilize VBA Starting in

2000 ( 4.0),Access Jet there is a new syntax for

,creating queries with parameters in a way that

,looks like creating stored procedures but these

procedures are still limited to one statement per

.procedure [2] Microsoft Access does allow forms to contain code that is triggered as changes are

(made to the underlying table as long as the

),modifications are done only with that form and it

-is common to use pass through queries and other

http://en.wikipedia.org/wiki/Stored_procedure




techniques in Access to run stored procedures in

RDBMSs .that support these

In ADP ( 2000 ),files supported in Access and later

-the database related features are entirely

,different because this type of file connects to a

,MSDE or Microsoft SQL Server instead of using the

. , Jet Engine Thus it supports the creation of nearly

(all objects in the underlying server tables with

, ,constraints and triggers views stored procedures

- ). , , ,and UDF s However only forms reports macros

(and modules are stored in the ADP file the other

- ).objects are stored in the back end database

Creation of ADP files has been dropped in Access

2007 ;however ADP files can still be opened and

.run

Development

Access allows relatively quick development

,because of very good GUI design tools and high

.level integration of GUI design and data objects

, , ,All database tables queries forms and reports are

. ,stored in the database For query development ,Access utilizes the Query Design Grid a graphical

user interface that allows users to create queries

without knowledge of the SQL programming

. ,language In the Query Design Grid users can


http://en.wikipedia.org/w/index.php?title=Access_database_project&action=edit&redlink=1


http://en.wikipedia.org/w/index.php?title=Access_database_project&action=edit&redlink=1



" "show the source tables of the query and select

the fields they want returned by clicking and

.dragging them into the grid Joins can be created

by clicking and dragging fields in tables to fields .in other tables Access allows users to view and

.manipulate the SQL code if desired

, The programming language available in Access is

as in other products of the Microsoft Office ,suite

Microsoft Visual Basic for Applications. Two

database access libraries of COM components are

:provided the legacy Data Access Objects ( ),DAO

(which was superseded for a time but still

)accessible by ActiveX Data Objects ( );ADO

( )however DAO has been reintroduced in the latest

, 2007.version Microsoft Access

Many developers who use Access use the

Leszynski naming convention, though this is not

; ,universal it is a programming convention not a

- .DBMS enforced rule [3] ,Except in VBA it is also

made redundant by the fact that Access

categorises each object automatically and always

, :shows the object type by prefixing Table or :Query before the object name when referencing a

.list of different database objects

Microsoft Access can be applied to small projects

( 97the Access speed characterization was done for

32 )users [4] but scales poorly to larger projects with

100more than several MB of data or many users because of the way indexing and locking are

.handled As a Microsoft Access database can be

,cached locally when used on network processing

speed may be substantially better when there is

.only a single user Because of the effect of packet

,latency on the record locking system Access

databases are effectively too slow to be used on a

.Virtual Private Network or a Wide Area Network

Access includes an Upsizing Wizard that allows

users to upsize their database to Microsoft SQL

Server -if they want to move to an ODBC client

.server database

One recommended technique is to migrate to SQL

.Server and utilize Access Data Projects This allows

, ,stored procedures views and constraints using

. -standard SQL Additionally this full client server

design significantly reduces maintenance and

.availability problems

,Access allows no relative paths when linking so

the development environment should have the

(same path as the production environment though

" - "it is possible to write a dynamic linker routine in

VBA). This technique also allows the developer to

.divide the application among different files

Protection

If the database design needs to be secured to

,prevent from changes Access databases can be

/ (locked protected and the source code compiled)

. .by converting the database to an MDE file All

( , ,changes to the database structure tables forms

, .)macros etc need to be made to the original MDB

.and then reconverted to MDE

Some tools are available for unlocking and

'decompiling', although certain elements including

original VBA comments and formatting are

.normally irretrievable

, , , ,main objects are tables queries forms reports

, , .data access pages macros and modules

Main Components of MSAccess

Database

A database is files in which you store data include

;all the major objects related to the stored data

including objects you define to automat the use of

. ,your data In other database systems the term

database used to refer to only those files in which

.you store data

Table

.An object you define and use to store data Each

table contains information

,about a particular subject such as customers or

.orders

( ) Table contains Fields or columns that store



,different kinds of data such as a name or an

, , ( )address and Records or rows that collect all the

information about a particular instance of the

.subject

. .E g All the information about a company

( You can define a primary key one or more fields

) ,that have a unique value for each record and

one or more indexes on each table to help

.retrieve your data more quickly

Query

Query in an object that provides a custom view of

. ,data from one or more tables In Access you can

( )use the graphical query by example QBE facility

or you can write SQL statements to create your

. , ,queries You can define queries to select update

, .insert or delete data You can also define queries

that create new tables from data in one or more

.existing tables

Form

An object designed primarily for data input or

; .display or for control of application execution You

use forms to customize the presentation of data

.that your application extracts for queries or tables



. You can also print forms You can design a form

to run a macro or a Visual Basic procedure in

-response to any of a number of events for

,example to run a procedure when the value of .data changes

Report

, ,An object designed for formatting calculating

, .printing and summarizing selected data You can

.view a report on your screen before you print it

Data Access Page

An object that includes an HTML file and

supporting files to provide custom access to your

.data from Microsoft Internet Explorer You can

publish these files on your company intranet to

allow other users on your network who also have

2000 5Office and Internet Explorer version or later

, , .to view search and edit your data

Macro

Macro is an object that is a structured definition of

one or more actions that you want Access to

.perform in response to a defined event



,For example you might design a macro that

opens a second form in response to the selection

.of an item on a main form You might have

another macro that validate the content of a field .whenever the value in the field changes You can

include simple conditions in macros to specify

when one or more actions in the macro should be

.performed or skipped You can use macros to

, ,open and execute queries to open tables or to

.print or view reports You can also run other

macros or visual Basic procedures from within a

.macro

Module

It is an object containing custom procedures that .you code using Visual Basic Modules provide a

more discrete flow of actions and allow you to

' .trap errors something you can t do with macros

-Modules can be stand alone objects containing

functions that can be called from anywhere in

,your application or they can be directly associated with a form or a report to respond to events on

.the associated form or report



Table stores the data that you can extract with

queries and display in reports or that you can

.display and update in forms or data access pages

, ,Notice that forms reports and data access pages can use data either directly from tables or from a

" "filtered view of the data created by using

. ;queries Queries can use Visual Basic functions to

provide customized calculations on data in your

. -database Access also has many built in functions

that allow you to summaries and format your data

.in queries

" "Events on forms and reports can trigger either

.macros or Visual Basic procedures

ontrol Control is an object on a form or report that

.contains data You can even design a macro or a

Visual Basic procedure that responds to the user

pressing individual keys on the keyboard when

.entering data
