- IMDB database that match those search criteria. Your program must include the following requirements: Connect to the same database server, using the same account as in the IMDB browser (the server is cisdbss.pcc.edu, and the username and password are 275student). Write a program that fetches data about a particular name from the NAMES database. Use the NAMES database on that server instead of the IMDB database, and modify your query. Here's an example query that should produce reasonable results: SELECT Name, Year, Gender, NameCount, Total FROM all_data WHERE Name = 'Marc' AND Gender = 'M' ORDER BY Year; Running the query should fetch the following data - only the first five rows are shown: Name Year Gender NameCount Total 1 Marc 1915 M 13 848603 2 Marc 1916 M 14 890099 3 Marc 1917 M 9 925511 4 Marc 1918 M 18 1013537 5 Marc 1919 M 17 980149 The user should be able to enter a name and a gender, and…Explain how JPA and ORM work with a simple Java code example.

- demonstrate how to connect to a sqlite database. HOW TO SUBMIT YOUR ASSIGNMENT At the top of each of your C++ programs, you should have at least four lines of documentation: Program name (the C++ file name(s)), Author (your name), Date last updated, and Purpose (a brief description of what the program accomplishes). Here is an example: /* Program name: jbtictactoe.cpp* Author: John Doe* Date last updated: 5/1/2017* Purpose: Play the game of Tic-Tac-Toe*/ ASSIGNMENT: Database Connection Fact Database ER Diagram Write a program that opens a connection to the FACT database factdb.db Download factdb.db. If the connection doesn't open successfully print an error message from the database and end the program, otherwise print a success message. Then use a callback function to print the results of a select query (any select query of your choice) and close the database. To submit your assignment: Submit your source code file (*.cpp)There are three tables in this database (see image). Write MYSQL code for: (1) Create a trigger “insert_inventory” on table “Inventory”. The trigger is fired after a row is inserted in table “Inventory”. After a row is inserted in table “inventory”, the “itemid”, the insertion time, and the action is inserted in table “Inventory_history”. The action is set to ‘add an item’. The oldprice is set to null. Test your trigger by inserting a row into Inventory and displaying the contents of Inventory_history. (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 “Inventory” is decreased by 3. Test your trigger by inserting a row into Transaction and displaying the contents of the relevant row in Inventory. (3) Create a trigger “change_price” on table…Answer the following prompts 1The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system. The main idea is to take actions faster and minimize the time spent for the maintenance. Therefore, the Car Maintenance team wants to store MAINTENANCE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, create a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team. 2The Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Create a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the three fields. The CAR_ID and MAINTENANCE_TYPE_ID…
- Which of the following are true about primary keys? SELECT ALL THAT APPLY. A) They must reference one or more columns in a single table. B) They are usually implemented using an index. C) They guarantee that no two rows in a table have duplicate primary key values. D) They must be defined for every database table.To access a database, we need to open a connection to it first and close it once our job is done. Connecting to a database depends on the type of the target database and the database management system (DBMS). For example, connecting to a SQL Server database is different from connecting to an Oracle database. But both these connections have a few things in common: •They have a connection string •They can be opened•They can be closed•They may have a timeout attribute (so if the connection could not be opened within the timeout, an exception will be thrown).Your job is to represent these commonalities in a base class called DbConnection. This class should have two properties: ConnectionString : stringTimeout : TimeSpanA DbConnection will not be in a valid state if it doesn’t have a connection string. So you need to pass a connection string in the constructor of this class. Also, take into account the scenarios where null or an empty string is sent as the connection string. Make sure to…In what kind of situation would it make sense to make the assumption that two select statements taken from the same database are consistent with one another?
