I am working on a webapplication, which main functionality will be to present some data to user. However, there are several types of these data and each of them have to be presented in a diffrent way.
For example I have to list 9 results – 3 books, 3 authors and 3 files.
Book is described with (char)TITLE, (text)DESCRIPTION.
Author is described with (char)TITLE, (char)DESCRIPTION.
File is described with (char)URL.
Moreover, every type has fields like ID, DATE, VIEWS etc.
Book and Author are presented with simple HTML code, File use external reader embed on the website.
Should I build three diffrent tables and use JOIN while getting these data or build one table and store all types in there? Which attitude is more efficient?
Additional info – there are going to be really huge amounts of records.
The logical way of doing this is keeping things separate, which is following the 3NF rules o the database design. This gives more flexibility while retrieving different kinds of results specially when there is huge amount of data. Putting everything in a single table is absolutely bad DB practice.
