- 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.In 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.

- Create a database class in python. Create four variables for the database class: str_databasename, int_databaseid, lst_tablenames and int_count. str_databasename will store the name of the database, int_databaseid will store the identification number of the database and each identifier number is a unique number. lst_tablenames will store the list of tables for one particular database object. Int_count will store the number of tables for this database object.Use Python Programming - restaurant reservation program. The application offers different reservation rate for adults and children.
