Question 2 :
What difference between Fields and single value fields
multivalue field has the child values from a chind BC for the parent record configured through MVL. single value field will be either from the base table or joined table.
the Difference between Single Value Field (SVF) and Multi Value Field(MVF)
SVF- a field in BC which references a column in a table
MVF- a field in parent BC which references a field in child BC
Field-Identifies and defines a field in a business component. All fields making up a business component record contain entries from both Single Value Field and Multi Value Field object types.
Question 3 :
what is the difference between 1:1 and 1:M extension tables
A1: 1:1 extension table is like an extension to the base table. if we do not have the required table space in the base table for craeting new extension columns, we will use the 1:1 extension table's columns using an implicit join.
in contrast, 1:M extension tables are used for parent child relationship with the base table. where the 1:M extension has only related to the base table. for example, for a contact (S_CONTACT) there will be a number of specialities in the extension table(S_CONTACT_XM) with the parent child relationship.
A2: In Siebel for the base tables like S_CONTACT suppose you have 3 address for a perticular contact. A person is working at 2 places plus his home address. Now you can not store this is in S_Contact as every contact has a unique row id and that can not be repeated. So you have S_CONTACT_XM. i.e an extension table to S_CONTACT but with 1:M relation.
Question 4 :
What is complex join? Difference with Foreign key Primary Key join?
Complex joins are joins which have following diffrences from a PK-FK joins
# Complex joins can have conditional mappings like >,<,>=,NOT,AND,etc apart from '=' whereas the PK-FK joins are always '='.
# PK-FK joins are always (1-N), whereas complex joins can have (1 - 0,1) and (0,1 - N) kind of relationships
