- true /false The system-defined database used as a template for all “to be created” databases is the tempdb database. The entire contents of this database, including database options, are copied to the new database. Thus, if you modify this database, all databases created afterward will inherit those changes. OUTER JOIN types return only non-matching tuples. When we create a primary key (PK) some Database Management Systems (DBMS) automaticallly create a Foreign Key constraint on the attributes of the PK. SQL Server DBMS is one of these DBMSs. If a relation has more than one candidate key, we can implement this by creating a Primary Key constraint for one of the candidate keys, and a UNIQUE constraint for each and every one of the alternate keys. Using the Query Editor Window, “select TOP 1000 Rows” retrieves the first 1000 tuples of a relation (assuming that the relation has 1000 or more tuples).

- List the advantages and disadvantages of the three types of restrictions below. Support your response with examples: Rules and Defaults Constraints Triggers Briefly explain how and why one would need to add and/or remove constraints from a database.Database course: Convert the following ER diagram into a relational database schema, be certain to indicate primary keys and referential integrity constraints. (The photos complete each other) (I need the answer to copy it please)Assignment Brief: Some of the most difficult decisions that you face as a database developer are what tables to create and what columns to place in each table, as well as how to relate the tables that you create. Normalization is the process of applying a series of rules to ensure that your database achieves optimal structure. Normal forms are a progression of these rules. Each successive normal form achieves a better database design than the previous form did. Based on your understanding for the various normal form respond to the following problems and provide the optimal answer/solution. Problem#1: 1st Normal Form (1NF) Consider the Students table, with the primary key underlined, and the following data: Students: Alpha 100111 Email doe@usna.edu Name Courses GradePoints NN204, SI204, IT221 SM223, EE301 SI204 John Doe 2,3,3 Matt Smith 092244 113221 smith@usna.edu black@usna.edu 4,4 Melinda 3 Black NN204, SI204, IT221 090112 Tom Johnson Johnson@usna.ed 4,2,3 u a) Is the Students table…

What are the options for enforcing these constraints when a user attempts to delete a Dept tuple?FileStructure and Database CourseConsider the LIBRARY relational database schema shown in Figure 8.14, which is used to keep track of books, borrowers, and book loans. Referential integrity constraints are shown as directed arcs in Figure 8.14, as in the notation of Figure 5.7. Write down relational expressions also write the queries in SQL statements. for the following queriesFigure 8.18 will be attached a. How many copies of the book titled The Lost Tribe are owned by the library branch whose name is ‘Sharpstown’?c. Retrieve the names of all borrowers who do not have any books checked out.e. For each library branch, retrieve the branch name and the total number of books loaned out from that branch.g. For each book authored (or coauthored) by Stephen King, retrieve the title and the number of copies owned by the library branch whose name is Central.Case Study 2: Consider a database application which maintains the stock (product details) of a Hypermarket. The application performs various operations to help the shop owner to maintain the details about various products, selling in the shop. Following are the operations being performed using the application: Saving the details of any products when purchased from the dealer. Modifying the details of any products when it was purchased by the customer. Removing any expired product details. Displaying various reports based on the dynamic query given. With proper reason and example, describe all the necessary SQL commands will you use in this application.
