> h2. General DB Optimization
> In some production environments there were being experimented delays in most of the jobs.
A search for DB optimization was taken and some deficiencies were discovered, we can group
them in 4 groups:
> * Incorrect PRIMARY key
> * Duplicate PRIMARY KEY
> * Missing indexes (Add indexes to avoid full table scans)
> * Some views query (Change view to improve account retrieval speed)
