b) The following is the HTML code of a form: Student id: Student address: The form is associated with a table "student" in Oracle database. The table contains attributes "id" (primary key) and "name", which are strings with suitable lengths. A function connectDB(), which contains suitable username and password and returns an Oracle connection ID, has already been written in student.php and it can be used to connect to the database. (i) Write PHP code into student.php to transfer the data input in the form to the database table if both of the input fields are non-empty. Display an error message the query cannot be executed successfully. if Add PHP code into student.php to get the "id" from the form and display the id together with the name retrieved from the database if the "id" field is non-empty but the "name" field is. If the name cannot be retrieved, display a suitable message. (ii)
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…

Create the following indices, giving them an appropriate name in your spreadsheet (make sure to use the reverse-coded variable where relevant): Belief that climate change is a real phenomenon: Take the mean of scepticism_2, scepticism_6, and scepticism_7. Preferences for government intervention to solve problems in society: Take the mean of cog_1, cog_2, cog_3, cog_4, cog_5, and cog_6. Feeling of personal responsibility to act pro-environmentally: Take the mean of PN_1, PN_2, PN_3, PN_4, PN_6, and PN_7. When creating indices, we may be interested to see if each item used in the index measures the same underlying variable of interest (known as reliability or consistency). There are two common ways to assess reliability: either look at the correlation between items in the index, or use a summary measure called Cronbach’s alphaCronbach’s alpha A measure used to assess the extent to which a set of items is a reliable or consistent measure of a concept. This measure ranges from 0–1,…
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.

PS5: Webscraping Suggested Solutions Import BeautifulSoup, json, requesrts, and pandas. In [ ]: from bs4 import BeautifulSoup import pandas as pd import requests import re import json IMDB top 50 rated films. The following URL, https://www.imdb.com/search/title/?groups=top_250&sort=user_rating, is a link to the top 50 rated films on IMDB. Create a pandas DataFrame with three columns: Title, Year, and Rating, pulling the data from the webpage. We can do this in steps. First, get the HTML code that generated the webpage. In [ ]: Using the "Inspect Element" tool in a browser, see that each film is displayed in a DIV with the class lister-item. Use BS to find all such elements and store them in a list called films. Then, create a list of the title of each film. Notice, by inspecting the HTML, that the title is contained inside of a tag (a link) that is itself inside of a DIV with class lister-item-content . That is, for each film in the list films, find the div with the class…
