True or False :
___ Multiple Inheritance happens when a class has more than one sub-class. This problem can be observed in
___ Given two relations named A and B, if we q-JOIN A and B, the maximum number of attributes in the result relation could be (the number of attributes of A) times(*) the number of attributes of B).
____ * in an SQL SELECT statement means “all the tuples”.
____ In relational algebra, Cartesian Product (X) can be implemented using the q-JOIN operator. Cartesian Product ISA q-JOIN where q-condition always evaluates to true.
____ SQL is based on Predicate Calculus. A query in SQL always specifies what should be included in the query result.

- In Visual Basic, a double data type would be comparable to what SQL data type.Database: CUSTOMER (CustomerID, LastName, FIrstName, Phone, EmailAddress) PURCHASE (InvoiceNumber, InvoiceDate, PreTaxAmount, CustomerID) PURCHASE_ITEM (InvoiceNumber, InvoiceLineNumber, Item Number, RetailPrice) ITEM (ItemNumber, ItemDesciption, Cost, ArtistLastName, ArtistFirstName) Write an SQL statement to show which cutomers bought which items, and include any items that have not been sold. Include CUSTOMER.LastName, CUSTOMER.FirstName, IvoiceNumber, InvoiceDate, ItemNumber, ItemDescription, ArtistLastName, and ArtistFirstName,. Use a join using JOIN ON syntax, and sort the results by ArtistLastName and ArtistFirstName in ascending order. Note that in Microsoft Access this require multiple queries. From Database Concepts 9th Ed. (Kroenke)Computer Science A course and a teacher object have a many-to-one relation. You need to enable a function wherein a course cannot be saved without notifying the teacher. What should be done to accomplish the task?
- A computer store uses a database to track inventory. The database has a table named Inventory , with the following columns: ProductID INTEGER PRIMARY KEY NOT NULL ProductName TEXT QtyOnHand INTEGER Cost REAL Also assume that the cur variable references a Cursor object for the database. Write Python code that uses the Cursor object to execute an SQL statement that deletes the row in the Inventory table in which ProductID is equal to 12.Recurrence relations Write the first four terms of the sequence {an} defined by the following recurrence relations DO NOT COPY FROM OTHER WEBSITESIn java create an application to manage your data base information the database is already created in mysql tables, the tables are fill, So the user can use your database application user friendly Retrieve all data: Given a table name, retrieve all data from the table and present it to the user. Average: Given a table name and a column name, return the average of the column. Here the assumption is that the column type will be numeric (e.g., cost column). Insert: Given a table name, your program should show the column names of that table and ask the users to input new data to the table. In case of errors, your program should directly show the MySQL errors to the users. Assumption 1: Users will enter data according to the database constraints. Assumption 2: Users will input one record at a time. Delete: Given a table name, your program should show the column names of that table and ask the users to input data that they want to delete. Assumption 1: Users will enter data according to the…
- PATHS is a table that contains information about paths on a number line. The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6Data type 1.) Database Design : Take a crack at designing a simple database for 'A Small Dentist Office'. To keep it simple, please exclude any financial or billing information. So build a simple database that keeps track of patient information and appointments. Keep this very simple, maybe 4 tables. Part I: First determine the entities. The entities will be the tables. For example in an employee database the entities might be: an Employee, a Dept. These would then become the tables...the Employee table and the Dept table. Once you have come up with your 4 tables, move on to Part II. Part II: Design each table. Tables must include: a. Appropriate column names b. Data type for each column c. Whether a column can be 'null' or not d. Indicate any Primary Keys' and Foreign Keys'. e. Indicate any relationships with other tables PS → DO NOT USE MSAccess to do this Assign. I would use Excel for this Assign, or you could possibly use MS Word.Database Question:In this problem, you will come up with decision trees to predict if a planet is habitable based only on features observed by the telescope.In the table below, you are given the data from all 800 planets surveyed so far. The features observed by telescope are Size (“Big” or “Small”), and Orbit (“Near” or “Far”). Each row indicates the values of the features and habitability, and how many times that set of values was observed. So, for example, there were 20 “Big” planets “Near” their star that were habitable.Determine if Planet=Big and Orbit=Far is habitable? Derive and draw the decision tree learned by ID3 on this data.
