>C# movie manager programThe objectives of this assignment are as follows: To properly complete this assignment you will need to apply the following skills: Everything you need to understand accessing a database using ADO.NET can be found in chapter 2 of the book entitled SQL Server for C# Developers: Succinctly found in Blackboard. Note: There are no shortcuts; you must read chapter 2 from this book to begin to gain an understanding of what ADO.NET is and how to use it. Other materials specific to the controls that you will be using and how to code these will be provided to you in Blackboard. As a user I want a new Windows application written using Windows Forms that is capable of obtaining basic information from a SQL Server database related to movies that are entered into a database by programming students. Further I want the ability to add update and delete existing movies in the database. The work you will be doing is all part of a larger project. The application that results from this project when completed will be capable of finding a movie by its title and displaying some related information about the movie including the director the year the movie was released its genre category the Rotten Tomatoes score and the total box office earnings. The technology that we will be using to access our database is called ADO.NET. This is a data access technology that provides communication to and from data systems through a common set of software components. ADO.NET provides a bridge between your application and a back-end database; it is an interface to data. For a fairly complete walk-through of ADO.NET you must read the second chapter in the book SQL Server for C# Developers: Succinctly provided as a PDF in this class. The process of working with ADO.NET involves the following steps: The above steps are completely covered by the book as well as with the sample console-based application provided in Blackboard. Our database is hosted in AWS. Of course where the database is hosted is not consequential; we simply need a connection string to the instance of our database. The following connection string is properly formatted for this assignment: Ideally the connection string should be placed in and accessed from the applications App.config file. However it can just as easily be constructed through string interpolation. Examples of how to construct the connection string will be provided. What is of importance here is knowing that the above string represents exactly what the connection must contain. Important! You must not copy the string from above to your code. You will get additional spaces in the pasted version that will cause your connection to the database to fail. Within the CSCI1630 database we have a table called Movies. We will access this table to retrieve information about a given movie based on the Title the user provides to the applications interface. The schema of our table is shown to the left. You will need to construct a class in your application called Moviecontaining properties that match each of the columns in the table. Warning: for your application to work properly the names and data-types of your classs properties must match the names and data-types of the columns shown in our table. The varchar(number) data-type in SQL Server simply maps to a string data-type in C#. The number in the parenthesis example varchar(50) is the maximum length of the string in the table. This factors into our code in three meaningful ways: first we can use our knowledge of the length of a given column to properly provide enough length for the fields on the form; second we need the length of each column when we add parameters to the SQL command passed to the database. For a full discussion of parameters you must read chapter 2 from the book SQL Server for C# Developers: Succinctly; And finally knowing the maximum length of a column should factor into our error handling for the application. For example we want to prevent the user from entering either a title or director where the length of the string is greater than 50 characters. The SQL commands that you will use throughout the application will be provided to you. Two of the columns in our table: RottenTomatoesScore and TotalEarned are marked as allowing null values. This means that any individual row in the table might have no values for these two columns. Your program must protect against this. If you dont specifically code to check for nulls then when the user tries to find a movie where one or both of these values are null your program will end in an execution error. This is shown in the section Querying your database on pages 22 through 24 of the SQL Server for C# Developers: Succinctly book. You do not need to format your output to look like these examples. You simply need to ensure that you have met the technical requirements for this application. Following is example of the main page for this application: The following example shows the Maintenance menu expanded with its three options: The following example shows the Add Movie Screen: The following example shows the Update Movie Screen with data loaded: The following example shows the Delete Movie Screen with the delete prompt: In this final example the About form is shown:
