I. INTRODUCTION
In NoSQL Databases, End user uses various databases
to store and maintain the data. Relational databases
used in most of the application, but they have
disadvantage of storing and operating. To handle
complex databases such as rapidly changing data and
slowly changing data the relational databases are
effective. For handling unstructured data NoSQL term
is used. NoSQL is the methodology which consists of
several tools to handle unstructured data that can be
used for updating and changing the data in real
scenario. NoSQL database is mainly based on types of
data, time for loading data and throughput of data
NoSQL can be termed as ‘Not-Only SQL’. The
advantage of NoSQL is processing unstructured type
of data like social media, multimedia, emails. NoSQL
can handle more amounts of data in within minutes.

Only SQL’. The
advantage of NoSQL is processing unstructured type
of data like social media, multimedia, emails. NoSQL
can handle more amounts of data in within minutes.
NoSQL Mainly follows BASE properties i.e.
Basically Available Soft State and Eventually
Consistent. NoSQL don’t have Tables i.e. Rows and
Columns. It works on Data and Key Identification. It
is based on the requirement of user or application, the
correct and appropriate NoSQL database is used. Each
database has its own data model structures and
functions.
II. Types Of NoSQL Database:
Document Database: It has a key
The key is related to document. In document database
XML, JSON, BSON, YAML such languages are
used.
Graph Database: Graph Database used fo
of data. Node contains entities and edges show the
relationship. It can be directed/ non
edged means no edged between nodes. Facebook is
efficient and scalable for this kind of database. Ex.
Neo4j
BigTable Database: Simplest type of database. Every
single value is stored in attribute & associated with its
value. The data replication can be used. With the help
of Timestamp user can obtain information about data.
It based on map-reduce framework. Ex. Google,
Cassendra, HBase.
Columner Database: It is familiar with RDBMS. It
uses Row-Wise storage to store column data together
instead of row. Column is single in every disk block
gibe advantage to the faster querying.

III. BENEFITS OF NOSQL OVER RDBMS
Compare with RDBMS, the NoSQL is more scalable,
more flexible & gives higher performance.
1. Dynamic Schema: In NoSQL database, data can
be stored into the database without requiring any
schema. It makes faster development and integration
of code and takes less database administrator time.
2. Auto-sharding: In structured, relational database
scales vertically, a single server is been used to
stored data. The transactions are done using cross
table and joins. This can be get expensive, limited to
scale and can create more no. of failures. Instead of
using single server, the multiple servers are for
getting more capacity, this is called as sharding.
NoSQL database, support for auto-sharding means
they automatically spread the data across multiple
servers without requiring server pool. When any
servers suffer from failure, it can be replaced
automatically without requiring special application.
3. Replication: Most of the NoSQL databases also
support automatic replication to maintain reliability &
availability of data. NoSQL database are self-healing,
which gives automatic fail over & recovers as well as
availability of database with geographical regions to
enable data localization.
4. Integrated Caching: NoSQL has been developed
with many caching capabilities, it creates the separate
caching layer, same of the NoSQL database offered
manageable and integrated database management for
higher throughput and lowest delays.
IV MONGODB
MongoDB is open source NoSQL database which is
document based database. The language used in
MongoDB is c++. 10gen began developing MongoDB
database in 2007 as a ‘Platform as a service’ which is
known as MongoDB.inc. In 2009, it was introduced
as an open source database server.
a. Features of MongoDB
1. Ad-hoc queries: Field, range queries and regular
expression supports in MongoDB for searching. This
query gives specific patterns and also supports
Javascript functions.
2. Indexing : The primary & secondary indexes are
available in MongoDB document.
3. Replication: MongoDB support for replication of
document. It can be consists of two or more replicas.
All read & write functions are done in primary replica
by default. Using built-in replication, Secondary
replica makes copy of primary replica. When any
primary replica fails, through election process, the
primary replica has been decided from secondary
replicas. Secondary replicas server to read function.
4. Load Balancing: MongoDB uses horizontal
sharding. MongoDB can be used over more than one
server, balancing the load or replicating data which
gives throughput when system fails.
5. File Storage: MongoDB used for storing files with
load balancing and replications features. This is called
grid file system.
6. Aggregation: Map-Reduce are used for
aggregating data in mongoDB. In SQL, usually used
group by clause for getting these kinds of results
aggregation function is used. The aggregation
functions are keeping together to form a pipeline.
b. The MongoDB Web Shell
The MongoDB web shell is application for described
the features of MongoDB terminal. It mainly consists
of 3 major parts:
User can access new MongoDB web shell through
any of the web browser. Most of the code is written in
Javascript and executed on the web browser. The
browser-based shell uses the back-end Mongodb
instance. The Back-end gives us:
 For Session management, the sandboxing is used
and accessing the multiple resources for the
database.

 Provides a framework to preload the data to the
assessable resource.
 Verifying the state of data.
Below three components helps us to familiarize the
concept and uses of mongodb web shell
1. Try.mongodb.org
The primary goal of this project is replacing existing
browser to try.mongodb.org the new version provides
the functionalities of JavaScript code and new
features for mongodb. This provides new features of
JavaScript and new tutorial of system.
2. 10gen Education
MongoDB web shell can be used on 10Gen Education
platform where users can develop programmes for
Mongodb very quickly. The assignments are given to
the students who want to learn MongoDB and they
can solve the assignment with individual installation
of MongoDB with the help of web shell.
3. MongoDB API Documentation
The MongoDB Web Shell with API reference pages,
which will part of documentation. This will be used
for fast testing for detailing on the page and
evaluating its effects comparing data sets.
c. Storage Engines of MongoDB
Now days, user dealing with massive database which
is also complex in nature so it’s needed to exclude the
redundancy.
Using plug-gable storage engines, we can achieve the
new applications storage problems increasing
capability of application and using a specific
hardware with the help of storage engine, it can
reduce the complexity of operations which are done of
MongoDB, so that users can access the multiple
applications across different application, so that they
achieve data modeling, scaling of data, providing
security to data, providing security to data and
provides different tools. Here we can run multiple
storage engines within in replica set makes easy to
manage the data. In the MongoDB, the data
automatically migrates between primary and
secondary replica set members, they are independent
of data format.
d. MongoDB architecture
MongoDB 3.0 supports two data storage engines
 MMAPv1 : This is improved version of the
storage engine used for mainly concurrency
control.
 WiredTiger: WiredTiger storage engine, the
benefits where the hardware utilization, higher
output and it.
Above are the data storage engines can be exist in
single replica set, which are managed by
MMS(MongoDB Management service) RockDB
engines provide key-valued pair of data storage.
HDFS storage engine and fusionIQ engine used for
file system.
Wired Tiger storage engine, it is new storage engine
for MongoDB which is developed by Berkley, the
most deployed software in the World. Its scalability
works on multi-processor architecture. It uses various
techniques ex. Message passing algorithm, lock free
algorithm, and hazard pointers and so on. To reduce
the overhead on CPU and Disk I/O management, it
uses particular file format and compression technique.
After updating the versions of wiredTiger, the storage
and data of replica will not disrupt.
e. Features of New Driver For MongoDB
 Wire Protocol Compression:
MongoDB used the wired protocol compression oplog
data can be compressed 20x allowing replica’s four
times faster. In this process, server uses the snappy
algorithm which will give benefit with speed and
compression of data.

Here, we requires the driver which compress the
conversions which done with servers some of
application uses snappy algorithm, but zb1b
algorithm, the most widely used and easily available,
when driver connects with server they should save
compression format. Between the client and server
can be avoided with the help of compression
techniques.
f. Drivers for MongoDB
1. OP.msg
This is one of the wire protocol is OP_MSG. This will
give high-performance with replacement of old wire
protocol.
2. Ye Olde Wire Protocol
This protocol holds three components write messages,
unacknowledged and a disposing cursor message.
Two messages are generate at the server side – one for
create cursor with query and another get more results
from cursors.
After innovating protocol, new messages are added
into ye-olde protocol i.e. commands. We are reusing
OP_Query, which explains query about cmd
commands. Users want to get acknowledged about
their writes, which implement and called after the
getLastError command.
Ye-Olde wire protocol’s OP_Insert msg
Inserting the document in this protocol is very easy
and efficient. Message header followed by documents
without delimiter.
3. Middle Wire Protocol
In the MongoDB 3.2 version, Middlewire protocol is
been used in which all the process has commands.
It has features of uniformity and flexibility which
helps us to enhance to add new features into the
MongoDB. It has some disadvantages:
1. It uses OP_Query on cmd.
2. After every writing it use acknowledgment
3. Efficiency is less.
4. Modern Wire Protocol
Modern wire protocol, release in 3.6 version of
mongoDB with new protocol.
In this, client and server uses same type of message.
This new message type added the combination of old
and new types of wire protocols. It is designed by
Mathias Stearn, which helps to create a robust
protocol as compare to new protocols
OP_Msg contains:
g. Case Study on MongoDB: Craigslist
Craigslist is popular job posting website which are
used about 570 cities, 1.5 Million new jobs are posted
every day. Craigslist holds millions of records in

different formats. Craigslist uses MySQL to stored
information, but later on the management and
flexibility of data cannot be reached, then they
migrate over 2 billion of data into mongoDB to
achieve scalability and flexibility. MySQL was used
for data storage, but does not gives scalability.
MongoDB has built in scalability, so Craigslist
chooses MongoDB to achieve scalability. In
MongoDB, each post which are included in record of
Craigslist database that are saved as single document
so that are saved as single document so that
mongoDB can save these changes without any high
cost migration
VII. Conclusion
In this Research Paper, We have gone through
NoSQL databases and its type, MongoDB with its
architecture and drivers. From above analysis we can
conclude that, NoSQL database can perform more
better and fastly than SQL database. In NoSQL,
mostly JSON language is used for CRUD functions,
so that it become much easy for updating documents.
The compression of data has been done in NoSQL
database automatically, so that it will take less space
to store and less time to access the data from database.
The SQL database can be transferred to NoSQL
database, that's why many companies migrate there
data into NoSQL database.
