We need to first make some adjustments to certain variables in Tableau and better understand the difference between Dimensions and Measures.
Dimensions (shown as blue variable names) are normally attributes about certain transactions that can't be summed or otherwise quantified (e.g., dates,
product numbers, invoice numbers, etc.), Measures (shown in green variable names), on the other hand, are normally the outcome variables we are most
interested in (e.g., invoice total, quantity shipped, etc.). Sometimes, Tableau misclassifies these variables and we need to make changes before we can
continue. In the shipping file, Tableau has classified Customer No. and Invoice No. as Measures instead of Dimensions. We need to set both of these as
dimensions.
• Right-click on Customer Number and press "Convert to Dimension."
• Repeat the previous step for Invoice Number.
What other "number" has been imported as a Measure instead of a Dimension? Please change it to a Measure Dimension using the…

After discussing with the manager of the driving school, we have documented the following requirements: Each student is identified by a unique number and is characterized by his last name, first name, an address, and date of birth. Each student may attend several training sessions (as much as he needs). Each session has a unique number and is characterized by a specific date and time. For each training session, the manager chooses a series of questions from a CD. Each CD is identified by a number and is characterized by a publisher name. Each CD consists of 6 series of questions, numbered from 1 to 6 and each series consists of 40 questions. Each question is identified by a number and is characterized by the question text, answer, level of difficulty and a theme. The same question may appear in several series with an order number for each series. For example, question number 35 may…arrow_forwardWRITE THE OF MYSQL IN PYTHON, JUST ANSWER THE 2ND QUESTION BY LOOKING AT THE FIRST QUESTION Create database and tables as given below by using Python.

- Develop a program that takes as input: 1- A relation R with a set of attributes. The number of attributes should be variable. 2- A set of functional dependencies F that holds on R. The number of functional dependencies should be variable. And your program should do the following: 1- Find and print out the list of all possible candidate keys, (not the super keys), of R based on F.arrow_forwardSelect from below ALL statements that are true. Select one or more: a. Adding locking and unlocking statements (in arbitrary ways) to transactions is sufficient to assure database consistency in concurrent schedules. b. A conflict serializable schedule assures database consistency. c. The "B" in "B+-tree" stands for "Binary". d. The search key field/attribute of a primary index for a table does NOT have to be the primary key of the table. e. If an index is a sparse index, it MUST BE a primary index. f. It is a good idea to allow ONLY SERIAL schedules because they guarantee database consistency.arrow_forwardIntegrate any programming language to mySQL with the implementation of Database Normalization and Creation of ER Model. What should I expect? 1. User login interface 2. An interface where I can input my details. (User registration form, Freshman Application Form, Credit Card Application Form, Bank Account Opening Form, and etc.) These are just samples, you can think of your own, of course. 3. From one whole big interface of registration form or any above-mentioned items, I should see the database normalization implemented from whole big table (1NF) to 3NF. The expectation is that the database should have 1NF table and lastly the 3NF tables.arrow_forward
- Problem: design a er diagram for a database to keep track of building inspections required by a department of Damaged Buildings (DB). DB building inspections are requested by builders every month. Each building inspection is either passed or not. Inspections have a type code (3 characters, e.g. PLU, FRM, ELE, etc.) and possibly sequencing requirements. Some inspections cannot be performed before other inspections, e.g. final plumbing inspection cannot be performed until the framing inspection is passed. Each inspection has a numeric score, with 75 or more out of 100 being sufficient for a pass status. Each inspection data contains the date of inspection, inspector identification, inspection score, and textual information about the inspection. The textual information can be updated later, but the score can never be changed. FODB maintains a pool of inspectors. Each inspector has a unique 5 digit employee ID, name, and date they were hired. They can conduct any type of inspection but…arrow_forwardIn order to demonstrate a single row function within a database, we employed a function referred to as "single row".
