Normalization

Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can easily handle them. It also eliminates insertion, deletion, and update anomalies.

Question

Need help in ER diagram
Write the SQL statements to create all of the necessary tables to represent the above diagram, representing as many constraints as possible. Note: you do not need to worry about specifying types for the fields, but you do need to provide suitable foreign key option(s).

You will need to create the database tables and choose sensible data types for each column.Make sure to maintain entity and referential integrity, and implement all the above constraints.Since other developers work in parallel on other parts of the system, you will need to strictly follow the above specification to correctly implemented in your database. Otherwise, the other software will not be able to use your database. This means, one needs to be able to rely on all constraints being correct, the spelling of table and column names being as given, and that the data types that you chose will allow for sensible data to be added to the database in the future.For testing purposes, you are asked to insert the data specified below into the tables, but no other data except this.In short:1. You will need to create the tables as specified2. You will need to add the data specified Please use the 3.sql and implement your tables using the sketched CREATE TABLE commands.

This question is related to the Database:- Suppose you are creating a database for a library management system. Explain how you would make a table for the "books" entity and insert some sample data, and then alter the table to add a new column for the "authorID" attribute and update "authorID" with some data. Finally, make a SQL query to retrieve all the books that were published after the year 2000. Note that this book schema has several columns, including "book_id" as the primary key, "title", "authorN", "publisher", "publication_year", "isbn", "language", and "num_pages". It also includes "available" column that is set to "true" by default and can be used to track the availability of the book. Please don't use handwriting...
