    For those of you asking for Entity type:
    There are 2 types of Entity, strong entity and weak entity.
    A strong entity is independent of any other entity and is always having a primary key.
    A weak entity Is dependent on strong entities and have some sort of partial discriminator key.
    From the above Analogy, where books may have a primary key in book title or Book number, it is a strong entity. Say a record of the books online resources is kept as an entity. The resources, as such don't have a primary key, and is totally dependent on the book itself. The resources are weak entities.

      Entity type is the formal definition or the heading.
      Suppose a table whose heading is
      Name age occupation
      Torres 30. Footballer
      Name,age, occupation is entity type.
      Entity is Torres.....
