Resource-Oriented Architecture offers advantages over other web-service architectures. It is based on a simple, scalable and highly standardised application-level protocol. Multimedia content is commonly managed using the MPEG-7. The MPEG-7 is a standard for representing audiovisual information that satisfies specific requirements based on syntax, semantic and decoding. Content descriptions under MPEG-7 can be organised and characterized without ambiguity. The MPEG-7 eXperimental Model (XM) includes the best performing tools for MPEG-7 normative and non-normative elements. In this paper, multimedia content is managed using the MPEG-7 eXperimental Model functionalities and provided using web-services technology. RESTful principles are the guidelines for achieving multimedia content storage and retrieval. Quantitative evaluation of the proposed web services has shown that this approach has better performance, in term of retrieval speed and storage space

Virtual reality (VR) uses computer technology to create a simulated environment that senses the user's actions and responds accordingly. There are three main forms of VR: through-the-window VR uses devices like mice and keyboards; immersive VR uses head-mounted displays to fully immerse the user; and second-person VR captures the user's image and inserts it into the virtual world. VR has applications in areas like education, medicine, engineering, gaming and more by providing safe, interactive experiences. However, VR also faces challenges with initial high costs and potential for isolation or psychological stress with prolonged use.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

The Aim of this project is to Design and Develop a mini Database Management
System (DBMS) a set of computer programs that controls the creation, maintenance, and the
use of a Database. A system software package that helps the use of integrated collection of
data records and files known as databases
Where End user can ask simple questions in a query language i.e. Structural
Query Language, SQL to Database System and system responds to its request of Database
through command line interface by the use of Relation Database Model. Queries allow the
user to describe desired data, leaving the DBMS responsible for planning, optimizing, and
performing the physical operations necessary to produce that result as it chooses.
By the use of programming language VC++ or Dev-C++ for writing programs but
not using of any database management system package already available in market.
1.2) PURPOSE
New categories of data can be added to the database without disruption to the existing
system.
To have a CLI, Command Line Argument Interface, in which user fires/queries it
question to Database through a Structure Query Language SQL same as that of Oracle, MS
SQL, etc.
A feature of Data Definition Language (DDL): Specifies a new base relation by giving it a
name, and specifying each of its attributes and their data types. A constraint NOT NULL may
be specified on an attribute.
Feature of Data Manipulation Language (DML): To retrievals Data from Database and
Updates, Delete and Insert Records
1.3) SCOPE
Scope is to Add new features of DBMS like Join Table, Alter Table and some other
features of DBMS to have Better and efficient Database Package . User use questions in a

15. Project Management
Project management includes planning, monitoring and control of people, process, tasks and
events that occur during the project development process. It is a very necessary activity for the
computer based projects. Project management process includes all those activities that run
during the whole duration of the project. The scope of the project management differs with the
person doing it. A software engineer manages his day to day activities, planning and monitoring
of its technical tasks. A project manager plans, monitors and controls the work of a team of
software engineer. Senior manager controls the interface between the business and the software
professionals. Building software being a complex task makes project management very important
part of software building process.
The management spectrum involves the focus on 4 P’s.
1.) People:-
It is base framework, defining the people management, recruitment,
selection, and training
2.) Product :-
Defining the objectives and scope
3.) Process:-
Defining the framework for activities
4.) Project:-
Management of project is the only defined way to manage the complexity
of the project.
3.1 Software Process Model:-
To solve actual problems in a project, a software engineer or a team of engineers
must incorporate a strategy that encompasses the process, methods and tools that are
focused on the software quality. This strategy is called as a process model or a software
engineering paradigm.
In this project we have used incremental model.
Incremental model:-In this model all the basic requirements of the clients are being studied
and first increment is delivered (also called as core product) and many supplementary
features remain undelivered. Then a plan is developed for the next increment while the first
increment is under review or evaluation by the user. Then the plan addresses the modification
of the core product focusing on other requirements of the user. This process is repeated until
all the requirements are not fulfilled. This can also be considered in a way that customer has
15
16. provided all his requirements and we divide it into phases. In this no integration is required as
the new increment is overwritten on the existing one.
3.2 Team Structure:-
The team structure is DEMOCRATIC DECENTRALISED (DD). The team comprises of three
members:--
ABHIJEET SINGH KALSI
Decentralized teams generate better solutions and have greater probability of success when
working on different problems. DD team structure is best applies to programs with low
modularity.
Based on the difficulty of the problem to be solved relatively low modularity of the project and
high volume of the communication required a democratic decentralized team structure is
proposed. This software engineering team has no permanent leader. Rather, “task
coordinators are appointed for short duration and then replaced by others who may
coordinate different tasks.” Problem solving is a group activity. Communication among team
members is horizontal. Decentralized team generates more and better solutions than
individuals. Therefore such teams have a greater probability of success when working on
difficult problems.
3.3) PROJECT PLAN
Software planning involves estimating how much time, effort, money, and resources
will be required to build a specific software system. After the project scope is determined and the
problem is decomposed into smaller problems, software managers use historical project data (as
well as personal experience and intuition) to determine estimates for each. The final estimates
are typically adjusted by taking project complexity and risk into account. The resulting work
product is called a project management plan.
Panning includes:-
1. Risk Planning.
2. Project Scheduling.
3.3.1 Risk Planning:-
Risk is an event that delays or destroys the project thus affecting the cost. Planning and
management of risks are intended to help a software team to understand and manage the
uncertainty during the development process. Thus plans are made not only to understand the
risk uncertainty but also to minimize the impact when things go wrong.
The steps involved in risk management are:
16
17. Risk identification
Analyzing risk and assessing the damage that it will do
Ranking the risk according to probability of occurrence and impact
Developing a plan to manage the risks with high probability and high impact
The work product of Risk is management is called as Risk Mitigation, Monitoring and
Management Plan (RMMM).
Risk Strategies:-
Reactive strategies – very common, also known as fire fighting, project team sets
resources aside to deal with problems and does nothing until a risk becomes a problem
Proactive strategies - risk management begins long before technical work starts,
risks are identified and prioritized by importance, then team builds a plan to avoid risks if
they can or minimize them if the risks turn into problems
3.3.2 Project Scheduling:-
Activity that distributes estimated efforts across the planned project duration by
allocating the effort to specific software engineering tasks.
Network of software engineering tasks that will enable the job to get accomplished on
time.
Done to avoid lateness in project.

19. Command Syntax
1) Create Table command
the CREATE TABLE command for specifying the primary key attributes,
secondary keys, and referential integrity constraints (foreign keys).
Key attributes can be specified via the Null and Not Null
Syntax CREATE TABLE <table_name> ( <att_name att_type
att_const> )
Example:
myDB> create table student ( userid integer not_null ,
name char(10) null )
myDB> create table employee ( emp integer not_null , ename
char(10) null , salary integer not_null , work char(20)
not_null , dept char(20) not_null )
2) Insert Command
In its simplest form, it is used to add one or more tuples to a relation
Attribute values should be listed in the same order as the attributes were
specified in the CREATE TABLE command
Important Note: Only the constraints specified in the DDL commands are
automatically enforced by the DBMS when updates are applied to the
database
Another variation of INSERT allows insertion of multiple tuples resulting from
a query into a relation
Syntax INSERT INTO <table_name> VALUES ( val1 , val2 , val3 , .....)
19
20. Example:
myDB> insert into student values ( 12345 , Harry-Potter )
myDB> insert into employee values ( SN123 , John , 50550 ,
Manager , Finance )
3) Select Command
Syntax
Type: 1 SELECT * FROM <table_name>
Type: 2 SELECT * FROM <table_name> WHERE <attribute>
<condition-operator> <value>.
Example:
myDB> select * from abc
USERID NAME
----- -----
123 abc
1 Records Selected...!
myDB> select * from student
ROLL NAME MARKS
----- ----- -----
6787 abhi 80.60

Used to modify attribute values of one or more selected tuples
A WHERE-clause selects the tuples to be modified
An additional SET-clause specifies the attributes to be modified and their new
values
Each command modifies tuples in the same relation
Referential integrity should be enforced
Syntax
UPDATE <table_name> SET ( <att> = <val> , ... ) WHERE <att> = <val>.
Example:
myDB> update student set rollno = 456 where name = John-
Sina
1 Record is updated successfully...!
myDB> update employee set salary = 75650 , dept = IT
where emp = E12345
1 Record is updated successfully...!
5) DELETE Command
21
22. Removes tuples from a relation
Includes a WHERE-clause to select the tuples to be deleted
A missing WHERE-clause specifies that all tuples in the relation are to be
deleted; the table then becomes an empty table
The number of tuples deleted depends on the number of tuples in the relation
that satisfy the WHERE-clause
Referential integrity should be enforced
Syntax
Type: 1 DELETE FROM <table_name>
Type: 2 DELETE FROM <table_name> WHERE <attribute> <cond>
<value>
Example:
myDB> delete from student where roll = 05642
1 Records Deleted Successfully...!
myDB> delete from Employee where dept = Finance
1 Records Deleted Successfully...!
myDB> delete from student
12 Records Deleted Successfully...!
6) DESC Command
Syntax DESC <table_name>
Example:
22
23. myDB> desc student
Column Type Constraint
------ ---- ----------
roll integer not_null
name char(10) not_null
marks integer null
No. of columns: 3
myDB> desc employee
Column Type Constraint
------ ---- ----------
emp integer not_null
ename char(20) null
salary integer not_null
dept char(25) null
No. of columns: 4
7) DROP TABLE
Syntax DROP TABLE <table_name>
Example:
myDB> drop table student
TABLE named ' student ' is deleted
successfully...!
myDB> drop table employee
TABLE named 'employee' is deleted
successfully...!
8) HELP
23
24. Syntax help
To open the help for user about the use of commands
9) Clear
Syntax clear
To clear the entire screen
10) QUIT
Syntax quit
To comes out of the application.

37. SYSTEM TESTING
The definition of the quality software is that it meets the clients functional and
performance requirements, has been developed and documented in adherence to sound
standards and practices, is maintainable and can absorb changes by being flexible. The main
aim of testing is not show the absence of errors but their presence. Testing is often conducted
in a planned manner. This project follows a phased, feature-based approach and hence testing
cannot be precisely broken down into a structured pattern. Although the unit, integration and
acceptance test plans are followed, yet it is more of a feature-oriented testing. Generally the
testing is done as follows:
Implement and test one feature at a time
Adds this to the existing feature
Testing and debugging combination as whole till the whole system is developed.
PSYCHOLOGY OF TESTING: -
The aim of testing is often to demonstrate that a program works by showing that it has
no errors. This is the opposite of what testing should be viewed as. The basic purpose of
testing phase is to detect the errors that may be present in the program. Hence, one should not
start testing with the intent of showing that a program works, but the intent should be to show
that a program does not work. Testing is the process of executing a program with the intent of
intent of finding errors.
TESTING APPROACH:
Debugging is used as a tool for testing in TURBO C.
Debugging:-
37
38. Programs errors are known as bugs and the process of detecting these errors is called
debugging. In other words, Debugging is an art of finding and correctness of detecting these
errors in the system. Debugging is the consequence of successful testing. That is, when a test
case uncovers the errors, debugging is the process that results in the removal of the errors.
Although debugging can and should be an orderly process, it is still very much an art.
A software engineer, evaluating the results of a test, is often confronted with a
“symptomatic” indication of software problem. Results are assessed and a lack of
correspondence between expected and actual is encountered. In many cases, the non-
corresponding data is “symptomatic” of an underlying cause as yet hidden. The debugging
process attempts to match symptom with the cause, thereby leading to error correction.

39. FUTURISTIC APPROACH
Graphical Interface for User
Connectivity with any other system who wants a Database, accepts the C/C++.
Query like Join two tables, foreign table, alter table
More variant of queries for Retrieving and manipulation of Database
Features of Normalization to be includes in the system
Condition like assignment, logical, relation in the where clause
Relationship between each & every table with one another
