Part A - Essay Questions (10 points each) Answer 6 out of 6
1. What is Database Management System? What are the Advantage and
Disadvantage of Database Management System? Explain in detail.
Ans.) Database Management System (DBMS) is a product for putting
away and recovering clients' information while considering proper safety
efforts. It comprises of a gathering of projects which control the database.
5

The DBMS acknowledges the solicitation for information from an
application and teaches the working framework to give the particular
information. In enormous frameworks, a DBMS assists clients and other
outsider programming with storing and recover information. DBMS permits
clients to make their own databases according to their necessity. The
expression "DBMS" incorporates the client of the database and other
application programs. It gives an interface between the information and the
product application. The advantages and disadvantages are mentioned
below:
Advantages of Database Management:
1) DBMS offers an assortment of strategies to store and recover information
2) DBMS fills in as a productive handler to adjust the requirements of
various applications utilizing similar information
3) Uniform organization strategies for information
4) Application software engineers never presented to subtleties of
information portrayal and capacity.
5) A DBMS utilizes different amazing capacities to store and recover
information effectively.
6) Offers Data Integrity and Security
7) The DBMS suggests respectability requirements to get an elevated level
of insurance against disallowed access to information.
6

8) A DBMS plans simultaneous access to the information in such a way, that
just a single client can get to similar information at once
9) Reduced Application Development Time
Disadvantages of Database Management:
1. Cost of Hardware and Software of a DBMS is very high which builds the
financial plan of your association.
2. Most database the board frameworks are regularly mind boggling
frameworks, so the preparation for clients to utilize the DBMS is required.
3. In certain associations, all information is incorporated into a solitary
database which can be harmed in light of electric disappointment or database
is adulterated on the capacity media
4. Utilization of a similar program at once by numerous clients in some cases
lead to the loss of certain information.
5. DBMS can't perform complex estimations
2. What is cloud? What is Cloud computing and the components of Cloud
Computing? Explain in detail.
Ans.) Cloud computing has been portrayed as an analogy for the
Internet, since the Internet is frequently drawn as a cloud in organize
outlines. Utilizing cloud computing, associations and individual clients
can utilize Web administrations, database administrations, and
7

application administrations over the Internet, without putting resources
into corporate or individual equipment, programming, or programming
instruments. Figure outlined underneath portrays the trades between
customer PCs and administrations in the cloud. Organizations use Web
programs, for example, Microsoft Internet Explorer or Mozilla Firefox to
get to applications. As should be obvious, servers store programming and
information for organizations. Some huge, entrenched equipment,
programming, and counseling organizations, for example, Cisco, Dell,
IBM, HP, Microsoft, SAP, and others are making monstrous distributed
computing tries, frequently with what are named "virtualized assets."
What is unmistakable about these methodologies is their capacity to
develop and adjust to changing business needs. That is, they are adaptable
to suit developing (or changing) request by clients. The model of
"programming as a help," additionally called SaaS, is remembered for the
idea of distributed computing.
1.) Client computers: A client computer is a processing gadget that
interfaces with a system in one of a few different ways, yet the term
ordinarily depicts a PC or workstation PC. Since client computer are
associated with systems of different PCs, if an assailant or an infection
deals with an arranged PC, it very well may be utilized as a take-off
platform to assault any or the entirety of the gadgets on the system.
8

2.) Distributed Servers: A Distributed Servers is an assortment of
autonomous parts situated on various machines that offer messages with
one another so as to accomplish shared objectives. In that capacity, the
Distributed Servers will show up as though it is one interface or PC to the
end-client. The expectation is that together, the framework can expand
assets and data while failures, as though one framework falls flat, it won't
influence the accessibility of the administration.
3.) Datacenters: A Data Center is a physical office that associations
use to house their basic applications and information. A Data Center plan
depends on a system of figuring and capacity assets that empower the
conveyance of shared applications and information. The key segments of
a Data Center configuration incorporate switches, switches, firewalls,
stockpiling frameworks, servers, and application-conveyance controllers.
3. What is Deployment Model and Service Model?.
Ans.) Deployment Model: A deployment model speaks to a
particular sort of cloud condition, basically recognized by proprietorship,
size, and access. There are four regular cloud arrangement models: Public
Clouds Private Clouds and Hybrid Clouds.
9

 Public Cloud: A cloud is called public when administrations
are rendered by outsider suppliers over a system open for open use,
implying that you share a similar equipment, programming, and system
gadgets with different customers of a similar supplier (different
organizations, for instance). Another significant differentiator between a
public cloud and a private one is the duty over the cloud's facilitating and
the executives. In an open cloud, since you are just "leasing" a space on
the cloud from an outsider supplier, he will be the one accepting the
expenses and the upkeep of the entire foundation.
 Private Cloud: A private cloud refers to a cloud deployment
model worked only for a solitary association, regardless of whether it is
truly situated at the organizations on location data center or is overseen
and facilitated by a third-get-together supplier. In a private cloud, assets
are not imparted to different associations, yet this additionally implies the
organization utilizing it is altogether liable for its administration, upkeep,
and ordinary updates – which can likewise get essentially more costly
than open ones.
 Hybrid Clouds: Hybrid Clouds as their name recommends,
are a mix of private and open cloud sending models that are bound
together to give the advantages of the two foundations to the organization
utilizing them. By utilizing a Hybrid Clouds associations are equipped for
moving information and applications among private and open mists
10

relying upon their motivations. For instance, if there should be an
occurrence of high-volume, less reasonable information that doesn't
require solid security layers, open mists are the better choice as they give
greater ability to their clients. Be that as it may, if the organization needs
to store and oversee delicate information identified with basic business
activities, it is normally prescribed to utilize a private cloud as it gives
greater security.
Service Models are the reference models on which the Cloud Computing
is based. Types of service models are as follows:
 SaaS (Software as a Service): This sort of open distributed
computing conveys applications over the web through the program. The
most well known SaaS applications for business can be found in Google's
G Suite and Microsoft's Office 365; among big business applications,
Salesforce stands out. In any case, basically all venture applications,
including ERP suites from Oracle and SAP, have embraced the SaaS
model. Normally, SaaS applications offer broad setup alternatives just as
improvement conditions that empower clients to code their own
adjustments and increases.
 IaaS (Infrastructure as a Service): At an essential level,
IaaS open cloud suppliers offer register administrations on a
compensation for every utilization premise. In any case, the full cluster of
administrations offered by all significant open cloud suppliers is faltering:
11

exceptionally adaptable databases, virtual private systems, huge
information examination, engineer apparatuses, AI, application checking,
etc. Amazon Web Services was the primary IaaS supplier and remains the
pioneer, followed by Microsoft Azure, Google Cloud Platform, and IBM
Cloud.
 PaaS (Platform as a Service): PaaS gives sets of
administrations and work processes that explicitly target designers, who
can utilize shared devices, procedures, and APIs to quicken the turn of
events, testing, and sending of utilizations. Salesforce's Heroku and
Force.com are well known open cloud PaaS contributions; Pivotal's
Cloud Foundry and Red Hat's OpenShift can be conveyed on premises or
got to through the significant open mists. For endeavors, PaaS can
guarantee that designers have prepared access to assets, follow certain
procedures, and utilize just a particular exhibit of administrations, while
administrators keep up the hidden foundation.
4. What is the role of MIS in today's business? What is the evolution of
WEB? Explain in Detail.
 Ans.) Operational excellence is the accomplishment of more
elevated levels of profitability and productivity. Data frameworks can help
accomplish operational greatness by improving correspondences to provider and
12

streamlining the gracefully chain. Data frameworks could assist administrators
with speaking with laborers all the more productively, empower mechanical
advancement in items, limit stockroom overhead, smooth out appropriation.
 Organizations have been utilizing data frameworks to expand
devotion and create more grounded associations with clients. Having a system
on client/provider closeness makes clients and providers significant partners
inside the association and they will feel increasingly esteemed. With the
expanded utilization of the Internet, building up a solid relationship with the
two clients and providers is urgent for endurance in such a serious market where
customers approach any data. Comparable to providers, data frameworks have
empowered providers to approach creation timetables of the firm thus, they
have more notification of when to have materials prepared. On the client side,
data frameworks permit firms to monitor inclinations so they can make future
suggestions to clients or they won't have to pose similar inquiries each time the
client utilizes their great/administration. A case of this is in lodgings when a
data framework can store data about favored registration times, television
programs and so forth.
 A Competitive Advantage is accomplished when an association
can do any a certain something, process, work, and so on more viably as well as
effectively than others in that industry fragment or at times over the whole
business. Regardless of whether the association utilizes an ease technique,
cost/value separation, or what have you there is an Information System
13

supporting the capacity. A very much arranged and executed Information
System is basic in the present business world. Very much arranged and
executed Information Systems are key devices for the errand of acquiring a
Competitive Advantage.
The revolution of WEB is as follows:
 Web 1.0
Web 1.0 began in the 60s, as the most essential structure, with text-
just programs, for example, ELISA, at that point rose HTML that made
pages increasingly lovely to the eye, and the primary visual programs like
Netscape and Internet Explorer. This Web is perused just, the client can't
collaborate with the page content and it is restricted to what the
Webmaster transfers to the site.
 Web 2.0
The term Web 2.0, marked by Tom O 'Reilly in 2004 alludes to a
second era of models of Web pages. It is comprehended as another way
of thinking of navigation, another approach to take an interest in the
system. His antecedent, Web 1.0, has a progressively static route model,
this new organization energizes dynamic interest. The client is not, at this
point constrained to access to data, rather makes it.
 Web 3.0
Another term, Web 3.0 seemed to relate the semantic Web. It is an
augmentation of the World Wide Web, by which information can be
14

found in any language and in positions appropriate for a wide range of
programming. It depends essentially on data and its structure, which
permits the client to think that its all the more rapidly and viably. Web
3.0 is a neologism used to depict the development of the utilization and
cooperation in the system through various ways. This incorporates
changing the system into a database, a move planned for making content
available by various applications that are not simply the program, the
push of computerized reasoning advancements, the geospatial web, 3D
Web.
5. What is General Data Protection Regulation? Explain in detail.
Ans.) The General Data Protection Regulation (GDPR) is a lawful
structure that sets rules for the assortment and handling of individual data
from people who live in the European Union (EU). Since the Regulation
applies paying little heed to where sites are based, it must be noticed by
all locales that pull in European guests, regardless of whether they don't
explicitly showcase merchandise or administrations to EU inhabitants.
The GDPR orders that EU guests be given various information
divulgences. The site should likewise find a way to encourage such EU
purchaser rights as an ideal notice in case of individual information being
penetrated. Embraced in April 2016, the Regulation came into full impact
in May 2018, following a two-year change period. Oversees the capacity
15

and handling of information instead of its assortment. It additionally
incorporates some significant purchaser rights:
o The right to be informed,
o The right of access,
o The right to correct errors,
o The right to erase data,
o The right to restrict processing, and
o The right to take it elsewhere (data portability).
The GDPR orders a benchmark set of measures for organizations
that handle EU residents' information to all the more likely protect the
preparing and development of residents' very own information. The
purpose behind the GDPR is to force a uniform information security law
on all EU individuals, with the goal that every part express no longer
needs to compose its own information insurance laws and laws are
reliable over the whole EU. Notwithstanding EU individuals, note that
any organization that business sectors merchandise or administrations to
EU inhabitants, paying little mind to its area, is dependent upon the
guideline. Thus, GDPR will affect information assurance prerequisites
comprehensively.
6. Explain Database System Architectures & Data Model
16

Ans.) Database management systems architecture design will
assist us with understanding the segments of database framework and the
connection among them. The architecture of DBMS relies upon the PC
framework on which it runs. For instance, in a customer server DBMS
design, the database system at server machine can run a few requests
made by customer machine. We will comprehend this correspondence
with the assistance of outlines.
1. Single tier architecture: In this kind of architecture, the
database is promptly accessible on the customer machine, any solicitation
made by customer doesn't require a system association with play out the
activity on the database. For example, lets state you need to get the
records of representative from the database and the database is accessible
on your PC framework, so the solicitation to get worker subtleties will be
finished by your PC and the records will be brought from the database by
your PC too. This kind of framework is by and large alluded as local
database system.
2. Two tier architecture: In two-tier architecture, the Database
system is available at the server machine and the DBMS application is
available at the customer machine, these two machines are associated
with one another through a dependable system. At whatever point
customer machine makes a solicitation to get to the database present at
server utilizing a question language like SQL, the server play out the
17

request on the database and returns the outcome back to the customer.
The application association interface, for example, JDBC, ODBC are
utilized for the collaboration among server and customer.
3. Three tier architecture: In three-tier architecture, another layer
is available between the customer machine and server machine. In this
engineering, the customer application doesn't discuss legitimately with
the database frameworks present at the server machine, rather the
customer application speaks with server application and the server
application inside speaks with the database framework present at the
server.
A model is a reflection procedure which shroud unnecessary
details. Data modeling is utilized for speaking to substances and their
relationship in database. Data model is an assortment of ideas which is
utilized to depict structure of a database which gives essential intends to
reflection. The structure of a database implies that holds the information.
 High Level-conceptual Data Model: User level
information model is elevated level or theoretical model. It gives ideas
which are near way that numerous clients see information.
 Low level-Physical Data Model: It gives ideas that depict
subtleties of how information is put away in PC model. Low-level
information model is just for Computer pros not for end-client.
18

 Representation Data Model: It is between High level and
Low level information model which gives ideas that might be
comprehended by end-client however that are not very far expelled from
way information is composed by inside PC. The most well-known model
are:
 Relational Data Model : The Relational Model uses an
assortment of tables and relationship among those tables. Tables have
different segments and every section has an interesting name. The
primary bit of leeway of this model is its capacity to speak to information
in an improved arrangement. The way toward controlling records is
improved with utilization of certain key ascribes used to recover
information.
 Network Model: The information in organize model are
spoken to by assortment of records and connections among information
are spoken to by joins, which can be seen as pointers. The records in the
database are composed as assortment of discretionary gatherings. The
principle bit of leeway of this model is its portrayal of connections
between elements is executed utilizing pointers which permits portrayal
of discretionary relationship.
