Normalizing an extremely big table

Question

I face the following issue. I have an extremely big table. This table is a heritage from the people who previously worked on the project. The table is in MS SQL Server.

Answer 1

1. Construct in your head and onto paper a normalized database structure
2. Construct the database (with indexes)
3. De-construct that monolith. Things will not look so bad. I would guess that A LOT (I MEAN A LOT) of data is repeated
4. Create SQL insert statements to insert the data into the database
5. Go to the persons that constructed that nightmare in the first place with a shotgun. Have fun.
