My Database Design

2. INTRODUCTION
One of the most vexing problems of
Enverga Lib.(RFS) is the unorganized collection
of clippings known as vertical files.
As a LIS student I find this problem very
interesting and it’s my pleasure to give some
contribution in organizing our vertical files
collection.

3. INTRODUCTION
As a student assistant in RFS I find it
difficult to assist our clients especially when
they are looking for the specific article in the
newspaper, because not all the clippings are
encoded in our system and take note that we
have a newspaper daily. That is the reason why
I ended up choosing this problem as my guide
for making my database design.
