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…
SQL: Create a SQL query that uses an uncorrelated subquery and no joins to display the descriptions for products provided by a vendor in area code 615. Remember, the main difference between a correlated subquery and uncorrelated subquery is that, in a correlated subquery, the inner query is dependent upon the outer query, while, with an uncorrelated query, the inner query does not depend upon the outer query. Instead, it runs just once. You should NOT use union, minus, or intersect in this query. The outer query will use the PRODUCT table and the inner query will use the VENDOR table [hint: you should have 9 records of output]. My code: select p_descript from product where (select v_areacode from vendor where v_areacode = '615' ; I am getting this error, problem is I can't see what is missing any assistance is appreciated.

Population Database You will find a program named CreateCityDB.java in Starting Out with Java: Early Objects (6th Edition) Chapter 15 Source Code. Compile and run the program (SEE BELOW). The program will create a Java DB database named CityDB. The CityDB database will have a table named City, with the following columns: Column Name Data Type CityName CHAR (50) Primary Key Population DOUBLE The CityName column stores the name of a city, and the Population column stores the population of that city. After you run the CreateCityDB.java program, the City table will contain 20 rows with various cities and their populations. Next, write a JavaFX application called PopulationDemo that connects to the CityDB database and allows the user to click any of the following operations: Sort the list of cities by population, in ascending order. Sort the list of cities by population, in descending order. Sort the list of cities by name. Get the total population of all the cities. Get the…

Hash Search Design a hash table which the phone number is the key word and can be used to do search. The phone number is looked on as key and thus the hash function should be designed based on it. Each record contains 3 data items, i.e. name, sex and phone number. Read the datum from txt file, use phone number as the key to design hash function, using open addressing method to solve conflicts. Build hash table and show highest number of hashes. There are 450 records in total, and the size of hash table is defined as 467. The maximum number of hashes is required to be no more than 80 When the user input a phone number, your program should do hash search based on this number. If the number dose exist then the corresponding information should be shown, and the number of hashes should be shown as well. If the number does not exist in the table, still show the number of hashes and the information: this number not exist In doing this the program should be done in C and it should be…
