1. A computer-implemented method for converting database formats based on user data access patterns in a cloud computing environment, comprising: identifying a first set of database tables based on a set of access patterns stored in a computer storage device, the first set of database tables having a first format, wherein the first format is a relational database format and the set of access patterns indicate at least one of: a set of user data queries, insertions, updates or deletions to data stored in the first set of database tables; augmenting at least one table of the first set of database tables to generate a second set of database tables having a second format and stored in a cloud data repository, the second set of database tables being a set of de-normalized tables; creating a mapping between the first set of database tables and the second set of database tables; generating a column set based on the at least one condition of the set of access patterns; using the column set as a key for the second set of database tables; and propagating at least one data operation to the second set of database tables based on the key.
