CLOUD COMPUTING

• Cloud computing is the use of computing resources (hardware

and software) that are delivered as a service over a network

(typically the Internet)

• Cloud computing entrusts remote services with a user's data,

software and computation. Cloud computing consists of hardware

and software resources made available on the Internet as managed

third-party services

• The goal of cloud computing is to apply traditional

supercomputing or high-performance computing power, normally

used by military and research facilities, to perform tens of

trillions of computations per second.

CHARECTERISTICS OF CLOUD COMPUTING

• On-demand self-service:

• Broad network access:

• Resource pooling:

• Rapid elasticity:

• Measured service:

BENEFITS OF CLOUD COMPUTING

• Achieve economies of scale – increase volume output or productivity with

fewer people. Your cost per unit, project or product plummets.

• Reduce spending on technology infrastructure. Maintain easy access to your

information with minimal upfront spending. Pay as you go (weekly, quarterly

or yearly), based on demand.

• Globalize your workforce on the cheap. People worldwide can access the

cloud, provided they have an Internet connection.

• Streamline processes. Get more work done in less time with less people.

• Reduce capital costs. There’s no need to spend big money on hardware,

software or licensing fees.

• Improve accessibility. You have access anytime, anywhere, making your life

so much easier!

• Monitor projects more effectively. Stay within budget and ahead of

completion cycle times.

• The confidentiality of data is a major concern in cloud security.

To achieve the confidentiality, data is stored in encrypted form on

cloud storage. But, it is difficult to perform any operation on

encrypted data.

• Searching on encrypted data is a major issue in cloud. There are

several solutions present in literature for searching over encrypted

data.

• cryptographic cloud storage : To address data leaks , data

owner need to encrypt all the data before uploading them , such

that encrypted data may be retrieved and decrypted by those who

have the decryption keys.

• However , encryption of data makes it challenging for users to

search and then selectively retrieve only the data containing given

keywords

DROP BOX

• Dropbox is a home for all our photos, docs, videos, and files.

Anything we add to Dropbox will automatically show up on all

our computers, phones and even the Dropbox website — so we

can access our stuff from anywhere.

• Dropbox also makes it super easy to share with others, whether

we are a student or professional.

• Dropbox allows users to create a special folder on their

computers, which Dropbox then synchronizes so that it appears to

be the same folder

LANGUAGE: JAVA

ava is object oriented programming that provide a way of

modularizing programs. Java follows Bottom-up approach in

Program design i.e Emphasis is on data rather than procedure.

Basic Concept Of Object – Oriented Programming

• Objects and Classes

• Data Abstraction and Encapsulation

• Inheritance

• Polymorphism

• Dynamic Binding

NETBEANS

• NetBeans is a software development platform written in Java. The

NetBeans Platform allows applications to be developed from a set

of modular software components called modules. Applications

based on the NetBeans Platform, including the

NetBeans integrated development environment (IDE), can be

extended by third party developers.

• The NetBeans IDE is primarily intended for development in Java,

but also supports other languages, in

particular PHP, C/C++and HTML5.

• NetBeans is cross-platform and runs on Microsoft Windows, Mac

OS X, Linux, Solaris and other platforms supporting a

compatible JVM.

Why Use NetBeans IDE?

• Works out of the box

• Freely available

• Open source

• Support for Java standards &other popular platforms, such as HTML5

• Deeply integrated Maven support

• Extensible Java desktop framework

• Powerful, award winning GUI Builder

• Profiling and debugging tools

• Customizable and extensible

Increase Developer Productivity

MySQL

• MySQL is an open-source relational database management

system (RDBMS)

• Its name is a combination of "My", the name of co-founder

Michael Widenius' and "SQL", the abbreviation for Structured

Query Language

•

22

Querying with Statement

• The executeQuery method returns a ResultSet object

representing the query result.

•Will be discussed later…

String queryStr =

"SELECT * FROM employee " +

"WHERE lname = ‘Wong'";

Statement stmt = con.createStatement();

ResultSet rs = stmt.executeQuery(queryStr);

Introduction to JDBC

• JDBC is used for accessing databases from Java applications

• Information is transferred from relations to objects and vice-versa

• databases optimized for searching/indexing

• objects optimized for engineering/flexibility

Seven Steps

• Load the driver

• Define the connection URL

• Establish the connection

• Create a Statement object

• Execute a query using the Statement

• Process the result

• Close the connection

Interaction with the Database

• We use Statement objects in order to

• Query the database

• Update the database

• Three different interfaces are used:

• Statement, PreparedStatement, CallableStatement

• All are interfaces, hence cannot be instantiated

• They are created by the Connection

CLASS DIAGRAM

• In software engineering, a class diagram in the Unified Modeling

Language (UML)

• It is a type of static structure diagram that describes the structure

of a system by showing the system's classes, their attributes,

operations (or methods), and the relationships among the classes.

ADVANTAGES

• Preserving data privacy and confidentiality.

• Data is stored secure in cloud server.

• Data owner distributes a single key for sharing large number of

documents to the user.

• User needs to submit a single trapdoor for performing keyword

search over number of shared files.
