1st Case Study: Product /Preference Liking [Ecommerce] Versatility Situation –

The CEO of www.purhaseitnow.com is David. He has so far been reportedly marketing 300k items throughout separate classes each day. There have been tons of dealers listed mostly on the platform who have millions of items.
David eventually finds that concerning the quality of goods offered by many retailers, his revenues are declining monthly. He then chose to classify the goods such that his clients could obtain decent products from the platform. He approached John, his CTO, to create that very same feature.
John proposed to him that unless they encourage consumers to provide reviews throughout the context of like & dislike on the brand they bought, they may prefer such items over most similar companies.

John and the Marketing Director collected some specifications and agreed to use the Agile technique to build them.

The Requirements:
1. Get Details of Apps by User Id
2. Get Product Information by ProductId
3. Get all User-Liked apps
4. Get the stuff you want from several users.

John solely has information on RDBMS, and it has proposed the following data model:
Table
1. Customer
a. Id of User
b. Name of Consumer
c. Address

2. The Product
a. Ids of Product
b. Name of Product
c. Definition of Item

3. Likes of User Product
a. Id of User (FK user table)
b. Id of Item (FK product table)
c. Timestamp
Shortly afterward, the last table accrued tremendous results, resulting in a device disparity.
They attempted to apply all methods of automation yet struggled to solve the problem.
They found after some searching that the very last two questions will not do well because of this.
1. Due to the broad catalog, the tables would be massive.
2. It would require more prolonged effort for products/users to retrieve
They employ you to resolve this since you have a specific background in NoSQL databases.
You might end up with a fantastic collection of databases, including schema architecture.
When You Have Completed Designing, You Must:
1. Provide details on the kind of database you use for GRAPH / RDBMS / NoSQL?
2. Deliver database details about why you chose it?
3. Provide descriptions of the schema alongside Primary/Composite/Clustering/Partition keys?
Enhancement to the issue above:
4. You must also revert product names to get enough items a person value.
Get all the names of users who enjoyed every product.
DOMAIN: BANK Case Study 2:
Statement of Problem:
A global bank recently hired our consultancy company to help increase the usability of their new network. There have been tons of records of transactions obtained by large programs.
MySQL's new storage is insufficient to manage all of the logs. The company also needs to address several joint ventures.
Core Issues:
You need to overhaul the current code and migrate your old data.
Tasks
You also provided endpoints or the path of log files where information is analyzed.
On the platform, you have multiple sites that might be a search site, promotional page, day page contract, etc. You must use this log and layout schema; thus, the steady demand counts every day can be collected.

1. Amount of clicks on the Android device's deal of the day page on 11 May 2017
2. Amount of clicks to address the IOS device page on 11 May 2017
3. Amount of clicks on the Chrome browser home page, 11 May 2017
4. Amount of clicks on the Firefox browser home page, 11 May 2017
Case Study 3: Application Customer Service Desk
 
Statement of Problem:
 
Develop a Customer Service Desk program to monitor and collect complaints from customers in such a family of Cassandra columns.
Cassandra table Help Desk captures these specifics seen in the photo attached.
The Action Time, Ticket Id, Customer Id, and rows are the primary keys. The Customer id column is translated into the Partition key. The documents are saved throughout the Ticket Id. Action Time sorted order. This would be to ensure that perhaps the specifics of the significant change are available first.
 
Task:
 
1.Build a Help Desk list according to the specifications described.
2.In Help Desk, additional info. Action Time ought to get the latest Timestamp for any document entered.
3.To view all of the information throughout the layout stated, just use CQL command.
4.Write the question set to download information from either a given date and period. Around 2017-11-12 19:14:00 and 2017-11-13 19:20:00, for instance.
 
Case Study 4: Application for Hotel Booking
 
Statement of Problem:
 
Create the application data model for a hotel suite booking. Access file available rooms.csv procured. Besides two small hotels with five bedrooms apiece, the available_rooms.csv document includes a month's stock levels.
 
Tasks:
 
1. Construct a table available-rooms-by-hotel-date with hotel-id while the separation key as required, according to date and room number columns are clustered.
2. High volume load to table available-rooms-by-hotel-data from rooms.csv available
3. Display all documents for just a specific hotel id (ex: AZ123) and room number in available rooms besides the hotel date (ex: 101). Note that both hotel-id and room-number are part of the primary composite key.
4. Exhibit all data in decreasing order of date for just a specific venue among two different incorporating data.
5. Continue writing a UDF that returns 1 when an option is available, otherwise return 0 Give a decision to both the UDF to show the table results available while the hotel date.

We also integrated a resume builder application to your LMS to encourage you in this effort.
Now, in only three simple steps, you would be capable of building a perfect resume. To use specific frameworks through multiple positions and designations, you would have unrestricted access. Anything you will have to do is sign in to your LMS and press mostly on the choice to build your resume option.

To ensure high performance, we have a small number of individuals in such a live session.
Alas, however, participating in a live class through registering isn't feasible. You should go over the sample class video, which can offer a good view of how are the courses, the consistency of teachers, and the degree of participation in such a classroom.
