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

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.

SQL Scripts for Creating and Inserting Sample Data: NOTE: I am giving only one insert script for each table rest of the data was inserted by access forms

CREATE TABLE CUSer ( SUID CHAR(10)NOT NULL, UserFirstName Varchar(30), UserLastName Varchar(30), UserAge INTEGER , UserEmail varchar(20), UserGender Varchar(2), User_Type Varchar(30), CONSTRAINT SUID_PK PRIMARY KEY (SUID) ); INSERT INTO CUSer Values ('12345678','Sachin','Tendulkar','44','saten@syr.edu','M','Faculty')

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

After Trigger:

You can see the capacity column of C203 has been updated
