In the process of performing the control work, the database "Sale of newspaper periodicals" was developed. Data tables describing the subject area were compiled, tables were designed and linked, several queries were prepared, several forms were designed and developed based on table data, several types of reports were created, button forms were designed and developed.

I enclose the text of the control work on 11 sheets.
I post some screenshots of the database.
Development environment: Microsoft Office Access.
