MongoDB is a cross-platform document-oriented database program that uses JSON-like documents with optional schemas. It provides high performance, high availability, and easy scalability. The document outlines the installation process for MongoDB on Windows, which involves downloading the installer file, running it to complete the installation, configuring the path variable to locate MongoDB files, and using commands like mongod and mongo to start the MongoDB service and open a connection. The conclusion indicates that MongoDB has now been successfully installed on the system.

EXPERIMENT NUMBER-1
AIM - INSTALATION OF MONGODB.
MONGODB-
MongoDB is a cross-platform document-oriented database program. Classified as a
NoSQL database program, MongoDB uses JSON-like documents with optional schemas.
MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License
(SSPL).
MongoDB is a cross-platform, document oriented database that provides,
high performance, high availability, and easy scalability. MongoDB works on
concept of collection and document.
Database
Database is a physical container for collections. Each database gets its own set of
files on the file system. A single MongoDB server typically has multiple databases.
Collection
Collection is a group of MongoDB documents. It is the equivalent of an RDBMS
table. A collection exists within a single database. Collections do not enforce a schema.
Documents within a collection can have different fields. Typically, all documents in a
collection are of similar or related purpose.
Document
A document is a set of key-value pairs. Documents have dynamic schema. Dynamic
schema means that documents in the same collection do not need to have the same set of
fields or structure, and common fields in a collection's documents may hold different types
of data.
Advantages of MongoDB over RDBMS
 Schema less − MongoDB is a document database in which one collection holds
different documents. Number of fields, content and size of the document can differ
from one document to another.
 Structure of a single object is clear.
 No complex joins.
 Deep query-ability. MongoDB supports dynamic queries on documents using a
document-based query language that's nearly as powerful as SQL.
 Tuning.
 Ease of scale-out − MongoDB is easy to scale.

2.  Conversion/mapping of application objects to database objects not needed.
 Uses internal memory for storing the (windowed) working set, enabling faster access
of data.
Why Use MongoDB?
 Document Oriented Storage − Data is stored in the form of JSON style documents.
 Index on any attribute
 Replication and high availability
 Auto-Sharding
 Rich queries
 Fast in-place updates
 Professional support by MongoDB
Where to Use MongoDB?
 Big Data
 Content Management and Delivery
 Mobile and Social Infrastructure
 User Data Management
 Data Hub

Installation Guide On Windows
Follow the below steps to install the proposed file:
Step 1: Open the file. We have installed for 64-bit version with the name as “MongoDB-
win32-x86_64-2008plus-ssl-v3.4-latest-signed”. It is saved in the Local Disk C:/, click on
the file where you’ve saved it to start the wizard.
Step 2: Click “Next“.
Step 3: Tick the check box next to ‘I accept the terms in the License Agreement’ and
again click on “Next“.
Step 4: Click “Complete” to install all the features of MongoDB. As for “Custom”, this
option would be used to install only the specific components of MongoDB and also if a
user wants to change the location of where the installation must be done.
Step 5: Click “Install” to begin the installation drive.
Step 6: After the installation has been finished. Simply, click “Finish“.

6. Configuration Through Mongo Shell
After the whole installation is done, the user must configure it.
Follow the below steps:
If you use “mongo” in the command prompt without configuring it, then it would give
an error. Hence, configure it first.
Step 1: Go to the local disk C and get into “Program Files“. There you’ll find a folder named
“MongoDB“.
Step 2: Open it and you’ll find a folder named “bin” i.e. binaries folder. You will have 15 to 17
files in it. Copy the path, as given in the snippet path i.e. C:Program
FilesMongoDBServer4.0bin
Step 3: Open Settings and search “Path”.
Step 4: Click on “Edit the system environment variable” and then click on “Environment
Variables“.
Step 5: In the Environment variable, you’ll see the path as given in the snippet. Click “Path”
and then press “Edit“.
Step 6: In the Path given at your system, delete the previous ones and add new “The copied
path” from binaries, and click “OK”.
Step 7: Open Command prompts and type “mongod” to start the service.
Step 8: Write command on the command prompt “mongo” to create the connection.
Step 9: Open Command prompt with admin privileges and type: md datadb to make a
directory which would be datadb at the same folder.
Step 10: Again, open Binaries i.e. “Bin” and find “mongod.cfg file”, if you find it, then copy
this file and paste it in the folder named “data” which is also in the MongoDB folder in C:/. If it
is not here then finding in the “data” folder might help, usually, it happens to be there.
Step 11: Open Command prompt with admin privileges and write this command: mongod –
config “C: datamongod.cfg” –install
Step 12: Again type the command: net start mongoDb
The MongoDB pops up with a message “The MongoDb Service was started successfully”.
You are now good on the go. MongoDB has been successfully configured.
CONCLUSION-
Thus we install MongoDB on our respective systems.
