The document is a report on a Visual Programming Assignment (UAS) submitted by Andriyan Dwi P. It details two programming problems solved using C# and Windows Forms. Problem 1 involves creating patterned stars in the console or windows form. Problem 2 creates a database login system with forms for login, data entry, editing, deleting and viewing records from a MySQL database. Screenshots are included showing the outputs and database forms created.
