Create a windows forms application with the following functionality:
Application works with data stored in a local SQL Server
instance,
a connection string to the database has to be easy modifiable (should be located in
the application's configuration file)
As a data source the Northwind database is used
The application works in the disconnected scenario
All employees are listed in the combobox in the left upper corner of the form, both
the first name and the last name are displayed
Below the combobox, detailed information are presented: First name, Last name, Title, Birth date and Superiors
Fields for First name, Last name, Title and Birth date are editable,
changes have to be visible in the application's GUI 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
