Then, print employee names with their salary and job title. Also, get the average salary for all employees.what is the best method to check a database for information entered into a search bar by a user? for example, my database will have many animals. i want to make sure they come up appropriately, or that a message will be shown to the user that the animal is not in this list. i need to create a function that will do thisYou need to use Java to connect with the mysql and create a simple mysql system. Databases "POS" have 4 tables 1. Staff_Info Staff_ID Staff_Name Staff_Pw Staff_Title 001 AA 1111 Manager 002 BB 2222 General Once the pos system opened, you need to ask the staff to enter the password.

- In Python, what happens when you try to access a key that doesn't exist in a dictionary? How can you handle this situation?NO CODE, ESSAY ONLY. EXPLAIN. Develop a program that implements any of the indexing types. Use methods to organize your code and do not forget to follow naming conventions.Some rows of the STUGRADE table of a school are shown below: STU_CODE CLS_CODE GRADE YEAR 291 111 3.1 2010 938 101B 2.3 2011 931 M101 3.3 2040 291 M101 3.4 2018 190 111 2.0 2021 931 321 3.9 2003 Suppose that STU_CODE is the student code (foreign key) and CLS_CODE is the class code (foreign key). Which of the following computes the average for each year of the student with code 931? a. SELECT AVG(GRADE) FROM STUGRADE WHERE STU_CODE = 931 GROUP BY YEAR b. SELECT AVG(GRADE) FROM STUGRADE WHERE STU_CODE = 931. c. SELECT AVG(GRADE) FROM STUGRADE GROUP BY STU_CODE = 931 d. SELECT AVG(GRADE) FROM STUGRADE WHERE STU_CODE = 931 GROUP BY AVG(GRADE)
- 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. Assumption 1: Users will enter data according to the…Given is a Python program that connects to a sqlite database and has one table called writers with two columnns: name - the name of a writer num - the number of works the writer has written The writers table originally has the following data: name, num Jane Austen,6 Charles Dickens,20 Ernest Hemingway,9 Jack Kerouac,22 F. Scott Fitzgerald,8 Mary Shelley,7 Charlotte Bronte,5 Mark Twain,11 Agatha Christie,73 Ian Flemming,14 J.K. Rowling,14 Stephen King,54 Oscar Wilde,1 Update the Python program to ask the user if they want to update entries or add new entries. If the name entered already exists in the writers table then the database record is updated, overwriting the original contents. If the name does not exist in the writers table, then add a new record with the writer's name and number of works. The following TODO sections must be completed. Check if a writer exists in the writers table If the writer exists in the table, locate an entry to be updated by writer's name and update the…Suppose in a movie database, a movie is identified by id, name, year and ratings where a movie might have a sequel. [Example: Mission: Impossible 2 is a 2000 American action spy film. This movie is sequel to 1996 film Mission: Impossible]. Movies are casted by actors where an actor has specific role [Example: MI 2 is starred (i.e., main character) by Tom Cruise] and an actor is identified by id, firstname, lastname and gender. A movie might have multiple genres [Example: MI 2 is characterized by three genres: Action | Adventure | Thriller]. A director who directs a movie is identified by id, firstname and lastname. We assume a movie can have at-most one director. [Example: John Woo is the director of MI 2 and he also directed well-known movies like 'A better tomorrow', 'Red Cliff', ‘Hard Boildeď’, ‘Face/Off'] Draw ER diagram with proper notation.
