Hi Kaushik,
I have done this once and can share our approach.
Step 1. Create a Household EntityType with attributes like last name, address, and anything else you would like to capture and store.
Step 2. Create a HouseholdToIndividual relationship type
Step 3. Load your individual data to a database and perform a group by Last Name and Address and generate an ID for each group. Each Group will represent a Household and Each Individual a Member. Create a load file of households and another of HouseholdToIndividual relationships form the result.
Step 4. Load to Reltio using the Console Data loader
For deltas you will need to rerun on a regular basis and compare the previous run. Using this to create 3 groups: households to create, households to update, households to delete.
I believe a householding solution is in the works to be integrated directly into the product soon that should make this even easier.
