The following schema is given (primary keys are bold): ARTWORK (ArtworkCode. Title, Author, BasicAuction Price, FinalSalePrice". NumParticipantingBuyers", FinalBuyerID") OFFER (ArtworkCode, BuyerID, Date, Amount) REQUEST AUCTION ENDING (ArtworkCode. Auction EndingDate, Description) Write the trigger to manage the following activities related to an online auction of artworks. The ARTWORK table contains the list of artworks sold at the auction. The OFFER table contains, for each artwork, a list of the amounts that have been offered by buyers interested in purchasing the artwork. The same buyer can make multiple offers for the same artwork on different dates. A request to end the auction for an artwork is generated (inserting a record into the table REQUEST AUCTION ENDING), If there was no offer for the artwork, the trigger ends with an error. Otherwise, you have to calculate the following information. (1) The final sale price of the artwork, corresponding to the highest amount offered…
# Lab 2 ## Scenario Code&Code is a small company dedicated to Software Development. Their engineering team, to which you belong, is working on writing a Web Application as an MVP for a new customer. The code name for this App is “Loggy”, which is meant to offer functionality for a personal journal where users can log their daily activities through text, voice and video. The first step will be to write the main functionality, which is essentially a Microblogging System where all the posts are automatically annotated with voice, video or text. As an initial step, you must create the skeleton of the back-end service for performing the automatic closed captioning under these assumptions: - The closed captioning is performed through an external service (AWS or GCloud). - There should be an internal controller that: - Receives the recordings to be processed from a requester - Sends the recordings to the external service - Receives its response - Updates the recoding with the resulting…

Use the class diagram above as well as the specific requirements below to develop your class: Class Members The attribute grades will store grades for students. StudentGrades(int) - Initializes grades to a new array with the specified number of elements. The grade values are zero. StudentGrades(int[]) - Initializes grades to the specified array. Ensure that the reference to the grades is not accessible outside of the class. copyArray(int[]) : int[] - Returns a copy of the specified array. getGrades() : int[] - Returns a copy of the grades. setGrades(int[]) : void - Sets the grades.

Need help with this Create a function named FahrenheitToCelsius() containing a single parameter named degree. Insert a statement that returns the value of degree minus 32 and then divided by 1.8. Create a function named CelsiusToFahrenheit() containing a single parameter named degree. Insert a statement that returns the value of degree multiplied by 1.8 plus 32. Add an onchange event handler to the element with the id “cValue”. Attach an anonymous function to the event handler and within the anonymous function do the following: Declare a variable named cDegree equal to the value of the element with the id “cValue”. Set the value of the element with the id “fValue” to the value returned by the CelsiusToFarenheit() function using cDegree as the parameter value. Add an onchange event handler to the element with the id “fValue”. Attach an anonymous function to the event handler and within the anonymous function do the following: Declare a variable named fDegree equal to the value…
First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "WeightedAvgDataAnalyzer" (without the quotation marks), that modifies the DataAnalyzer.java in Horstmann Section 7.5, pp. 350-351 according to the specifications below.The input file should be called 'data.txt' and should be created according to the highlighted instructions below. Note that even though you know the name of the input file, you should not hard-code this name into your program. Instead, prompt the user for the name of the input file.The input file should contain (in order): the weight (a number greater than zero and less than or equal to 1), the number, n, of lowest numbers to drop, and the numbers to be averaged after dropping the lowest n values.You should also prompt the user for the name of the output file, and then print your results to an output file with the name that the user specified.Your…
