Brick Tavern Inn Database System
• This Database System was created for a local restaurant called the Brick Tavern
Inn.
• We chose this particular business, because my group member is an employee
the Brick Tavern Inn.
• We developed forms, tables, queries, reports and finally a switchboard. To
implement a database system that will propel the Company's logistics and
hospitality.
Justification
• A Database System is needed for the Brick Tavern Inn because
technology is evolving at an extremely rapid pace. It is very
competitive and hard to sustain profitability in the restaurant
industry without technological advancements. By implementing our
database, immediate quantitative improvements will be noticed
from Top management, and mutually improve the qualitative side
as well.
