Problem Description
maintainsAssignment Project Exam Helpand stores all of the business transactions information
(e.g. properties, hosts, listings, booking, etc.) required for the management’s daily operation. As the business grows, M-Stay has decided to build a Data Warehouse to improve their analysis and work efficiency. However,https://.comsince the staff at M-Stay have limited Business Intelligence and Data Warehouse knowledge, they have decided to hire you to design, develop and quickly generate BI reports from a Data Warehouse.
The operational databaseAdd assignmentcheftables can be found at the MStay account. You can, for example, execute the following query:
select * from MStay.<table_name>;
The data definition of each table in MStay is as follows:

A. Transformationhttps://.comStage
The first stage of this assignment is divided into TWO main tasks:
1.Design a dataAdd assignmentchefwarehouse for the above M-Stay database. You are required to create a data warehouse for the M-Stay database. The management is especially interested in the following indicators:
● Number of reviews
● Number of listings
Prop_Rating_Location Number
Prop_Rating_Cleanliness Number
Prop_Rating_Value Number
Prop_Average_Rating Number
PROPERTY_AME
NITY Prop_ID Number
(PF) The table links property and amenity tables

AMENITY Amm_ID Number
(PK) The table stores all amenities information

Amm_Description Varchar2
● Average booking cost (find appropriate fact measures that can calculate the average booking cost)
The following is a list of dimension attributes that you should include in your data warehouse:
● Listing type
● Listing time [Month, Year]
● Listing season o (Spring: 9 to 11, Summer: 12 to 2, Autumn: 3 to 5 and Winter: 6 to 8)
● Listing maximum stay duration [short-term: less than 14 nights, medium-term: 14 to 30 nights, long-term: more than 30 nights]
● Listing price range [low: less than $100, medium: $100 to $200, high:
more than $200]
● Channels
● Booking duration [short-term: less than 30 nights, medium-term: 30 to
90 nights, long-term: more than 90 nights]
● Review time [Month, Year]
● Booking cost range [low: less than $5000, medium: $5000 to $10000, high: more than $10000]
For the attribute, ensure that it meets the requirements of the range or group specified in your submission, if required in the specification.
– Preparation stage.
Before you start designing the data warehouse, you have to ensure that you have explored the operational database and have done sufficient data cleaning. Once you have done the data cleaning process, you are required to explain what strategies you haveAssignment Project Exam Helptaken to explore and clean the data. The outputs of this task for Report are:
a) If you have done the data cleaning process, explain the strategies you used in this process (https://.comyou need to show the SQL to explore the operational database and SQL of the data cleaning, as well as the screenshot of data before and after data cleaning). Add
– Designing the data warehouse by drawing star/snowflake schema.
Design task A:
● How many long-term stay duration listings are listed on Facebook?
● How many listings are there in summer for an “Entire home/apt” in a medium price range?
● How many bookings were there for “Private rooms” with a short-term stay duration in 2015?
Note: the star schema you created in Design Task A as the highest level of aggregation Design task B:
In this assignment, consider the star schema you created in Design Task A as the highest level of aggregation. The M-Stay company manager wants to implement a drill-down function to explore more detailed information. Your task is to suggest several ways to increase the granularity of your fact tables from Design Task A. In other words, the manager wants to decrease the aggregation level of the fact tables you created in Design Task A.
The outputs of task A & B for Report are:
b) A star/snowflake schema diagrams for design task A (You can use Lucidchart to draw the star schema).
c) List suggestion of increase the granularity of your fact tables for design task B.
2. Implement design task A star/snowflake schema using SQL.
YouAssignment Project Exam Helpare required to implement the star/snowflake schema that you have drawn in
design task A. This implies that you need to create the fact and dimension tables in
SQL. The output is a series of SQL statements to perform this task. You will also need to show thathttps://.comthis task has been carried out successfully.
Note:
● If your Add assignmentchefaccount is full, you will need to drop all of the tables that you have previously created during the tutorials.
● If you have dropped all tables in your account and you still encounter the
ORA-01536: space quota exceeded for tablespace
‘TABLE_NAME’, please check your SQL code whether you have properly joined all tables. This issue was mainly caused when you did not do the table join properly as the number of records multiplied during the process.
The outputs of this task for Report are:
a) Screenshots of the table structure you created for Design Task A, including the dimension table and fact tables.
A sample of screenshots of the table structure

Conduct a data analysis using the star schema you created in Design Task A by writing SQL queries to explore the data further. Present your findings in a clear and concise manner, demonstrating your understanding of the dataset and highlighting any noteworthy observations or patterns.
The outputs of this task for Report are:
Assignment Project Exam Help1. Findings report: A detailed explanation of your findings, including any significant observations or patterns identified during the analysis.
