Database Mapping as Data Access Layer for Business logic
Posted on 2006-04-04
AS we know that during mapping of database to business
logic, We mapped table to class with columns to Properties.
but if we have complex queries with multiple joins
and "Group By" clause then what is the mapping of this
query to business ligic side plus how we display data
retrieved by query to the user.
How we handle other issues,
Keeping all aboive question in mind how we formed a Data Access Layer at Business Logic side , or what will be design look like.
How many Interfaces or abstract functionality it have.
Will you suggest a design or any good link that further
elobarate this design logic.
Thinks in advance!
Thanks in advance!
