TRANSCRIPT
Node.js with Sql Server · Install Node.js runtime and npm package manager
Import amazon json data to mongodb
· Start with mongod --dbpath "D:\db"
mongoimport --db amazon --collection videogames --drop --file "D:/Amazon
Data/Videogames/reviews_Video_Games.json"
On a separate cmd open and run mongo
Web Application
The front end is developed in Angular JS and the server side is developed in Node.js. For the database,
we stored Walmart data in SQL Server as a table and Amazon data in MongoDB as an Amazon
collection.
Here is the front page of the system which includes fields of product type, price range, and review range
for user input.
Two options are available if the user just wants to filter the product or if the user wants some
recommendation.
Two separate calls to the database materialize according to the request.
Code for the Application for Walmart:

nodeApp.use(cors());
var router = express.Router();
router.get("/Product", function (req, res) { var a = req.query.a; var b = req.query.b; var c = req.query.c; var d = req.query.d; var e = req.query.e; var query1 = "SELECT * FROM ProductData WHERE salePrice BETWEEN "+b+" AND "+c +" AND reviews_overallRating_rating BETWEEN " + d +" AND " + e + " AND categoryName='" +a+"'" console.log(query1); sql.connect("mssql://sa:Illuminati@28@localhost/walmartreviewdb").then(function () {

})
});
nodeApp.use("/", router);
nodeApp.listen("4467", function () { console.log("Started Listening at 4467..."); });
· CSS – app.css
/* app css stylesheet */
.menu { list-style: none; border-bottom: 0.1em solid black; margin-bottom: 2em; padding: 0 0 0.5em; }

.menu > li { display: inline; }
.menu > li + li:before { content: "|"; padding-right: 0.3em; }
.heading{ background-color: gainsboro;
}
Sample Output:
· Output with the basic input
· Recommend me for the same inputs.
A separate application for handing Amazon data is made. Source code for the application is as follows.
