Summary:
The resources of the Carnegie include rooms that a SU user could use at the library.
For instance, there are rooms like Offices, Stack Area, Classrooms, Computer Lab,
Computer Cluster.
All rooms have resources such as chairs & table and technology. Classrooms can be
booked by faculty.
Therefore if faculty wants to know which rooms has sufficient capacity then the
faculty can log into the app to find out about the room he/she wants to book.
The resources can be located in a room or outside a room. These resources are
classified based on resource types and also based on the different levels they are
located on.
Supposedly, other resources include dust bins, elevators, exits and entrances in the
Carnegie Library. User (student or faculty) can log into the SU Indoor Map to find out
these other resources.
The scope of my project is limited to identify the rooms and other resources and
their locations at Carnegie so that these details can be fetched by the SU Indoor
Outdoor app.
Major Data Question
The App will be used by two kind of users
 SU students and faculty
 Database administrator
Why would SU students and faculty query the database?
Faculty has the privilege to book rooms in Carnegie Library therefore if any professor
would like to know information regarding the rooms then the database would be
queried

4. 4
Students would like to locate the rooms and respective events in the room. Also,
students & faculty would like to locate the other resources such as drinking fountain,
washrooms, entrance, exits and elevators.
Why would database administrator query the database?
The database administrator would query the database in the event of finding out the
current status of any room or event. Administrator would like to query in order to
update the database. For example, if the semester changes and the events in the
room needs to be changed then it responsibility of the administrator to change it.
Also, if there is any reconstruction or reordering of any of the rooms then the
administrator must make changes in the database.

Business Rules
 Many users can use/search for many rooms
 A user of the App may search for one or many other resources
 The rooms are complete disjoint entities. A room can be a computer lab, computer cluster,
classroom, office or a stack area
 One classroom can have one class at a given time
Database Infrastructure:
The database infrastructure is based on client-server model. SQL server is used as the database engine
and access is used as the interface design tool. Data is inserted, deleted, updated and queried from the
SQL server database with the help of forms on Access. Useful data stored on SQL database can also be
viewed with the help of reports generated through access.

Trigger
Before Trigger
As you can see C203 has 20 chairs and 20 tables and capacity is 20.
What my trigger does is it updates capacity = chairs + tables
create trigger updateCRooms
ON CROOMS
FOR UPDATE
AS
BEGIN
UPDATE CROOMS
SET Capacity = a.Capacity
FROM (select c.RoomNumber AS rnum,(c.no_of_tables +i.No_Of_Chairs) As 'Capacity'
FROM CROOMS c Inner join inserted i
on i.RoomNumber = c.RoomNumber
)a
where Crooms.RoomNumber = a.rnum
End;
update CROOMS
set No_Of_Chairs= 20
where RoomNumber='C203'

23. 23
After Trigger:
You can see the capacity column of C203 has been updated
