- EF Core API will create which table for the following context? In other words, what would be the table name in the database? public class SchoolContext : DbContext { public DbSet<Student> StudentList { get; set; } }A database for inventory and transaction of Apple store has been developed. There are three tables in this database – Inventory, Transaction, Inventory_history. You can use the following script to create the tables. create table Inventory ( itemid varchar(20) primary key, name varchar(30), price decimal(6,2), quantity int ); create table Transaction ( transid int auto_increment primary key, itemid varchar(20), quantity int, time datetime, foreign key (itemid) references Inventory(itemid) ); create table Inventory_history ( id int auto_increment primary key, itemid varchar(20), action varchar(20), oldprice decimal(6,2), time datetime, foreign key (itemid) references Inventory(itemid) ); 2) Create a trigger “change_quantity” on table “Transaction”. The trigger is fired after a row is inserted in table “Transaction”. After a row is inserted in table “Transaction”, update the “quantity” in table “Inventory”. For example, if 3 iWatch are sold, then the quantity of iWatch in table…Given the relational database shop defined in the script below; create database shop;use shop; create table users( id int null auto_increment, firstname varchar(255), lastname varchar(255) not null, primary key (id)); create table items( id int null auto_increment, name varchar(255), price float, primary key (id)); create table orders( id int null auto_increment, id_users int not null, id_items int not null, primary key (id), foreign key (id_users) references users(id), foreign key (id_items) references items(id)); write three SQL queries to answer the following questions 1.- All products(items) in the shop catalog; product code, name and price 2.- Products sold in the shop; product code, name and price and full name of buyer. 3.- Products in stock (not sold); product code, name and price
