Create a windows forms application with the following functionalities:
Application works with data in local SQL Server,
connection string to database has to be easy modifiable (should be located in configuration file)
As a data source Northwind database is used
Application works in disconnected scenarion
All employees are listed in the combobox in left upper corner of the form, both first name and last name is displayed
Below the combobox detailed information are presented: First name, Last name, Title, Birth date and Superiors
First name, Last name, Title and Birth date are editable,
changes have to be visible in the application and persisted in the database after application closure
Superiors are all other employees related, directly or indirectly, through "ReportsTo" field
Photo stored in "Photo" field is displeyed in right upper corner of the form (see hint below)
At the bottom of the form list of all orders related with selected employee are presented
All columns except "Value" come from "Orders" table
"Value" is an aggregated value of a single order, technically it is a sum of order details ("Order Details" table)
for given order (OrderID), where value of each detail is calclated as UnitPrice*Quantity*(1-Discount)
All rows with value greater than 1000 have modified background color
