Q.1 Consider the university database that keeps track of student and their mayor’s, transcripts, registration and the university course. Several sections of each course are offered and each section is related to the instructor who is teaching. IT also keeps track of the sponsored research projects of faculty and graduate students of the academic departments of the particular college. The database also keeps track of research grants and constracts awarded to the university. A grant is related to one principle investigator and to all researchers it support.

Q.2 ABC Engg. College is graded A college. It is five departments. The departments are headed by senior most & qualified faculty. The placement of final year students from all branches is managed by placement centre. Placement centre is managed by one of the faculty from any department. The teaching load of that faculty is zero. To assist placement centre head there are placement secretaries (whose teaching load is 13) from each department along with placement assistance from students (selected by placement center) of all five departments. Placement centre is responsible for on −campus & off campus recruitment of students. The placement process requires students resume & relevant documents along with approval from placement centre.

Companies invited on campus conduct test followed by interviews. The criteria of selection depend on academic performance & interview. For off−campus placements placement centre head must accompany students to the venue.

Q.5 Blood bank is a critical' entity in providing required type of blood to the patients at critical time. Their database

keeps track of the inventory of the blood, together with relevant information like blood group, date received,

location, date of expiry, donor, etc.

The database keeps information such as name, address~ and telephone' number of other blood banks in the area.

The reason for doing so is to get blood of a particular from other bank in case of emergency.

Method is defined. For each department we must record dept.no., deptname, budget, and employees

who work in that department.

You need to design a database for an Art Gallery.The database schema must keep

information about artists, their names (which are unique), birthplaces,age, and

style of art and a photograph. For each piece of artwork, the artist, the year it

was made, its unique title, its type of art (e.g., painting, sculpture, photograph),

and its price, along with the picture (Thumbnail) must be stored. The database

also stores information about Customers.

For each customer, the database stores that person's unique name, address, and

total amount of money spent in the gallery and the artists and type of art that

the customer tends to like (can be a text).
