Mapping Association Documentation vs Normal Database Terminology

[ssmusoke]

I am a new Doctrine 2 user, but I have found the association mapping documentation (https://github.com/doctrine/orm-documentation/blob/master/en/reference/association-mapping.rst) to be very confusing when compared to relationationla database terminology:

a) One-to-One Unidirectional and Bidirectional mappings are actually a one-to-many however, in the uni-directional version the parent does not have a mapping to the child while in the bi-directional one the parent does

b) One-to-Many is actually a many-to-many mapping which left me all fuzzled up.

c) Many-to-Many - I have not yet got that far

Since I am sure most developers have a database background, the concepts make it difficult to match the association mapping meanings to what the database ones are like.
