Some of the main advantages of using table for storing data are:-

  1. Stored data is persisted and is made durable even in times of any catastrophic failures. Since table is part of db backup in the event of any failures, table info can be restored from a backup to reclaim lost data

  2. Provides ability to introduce relationships between various data by means of referential constraints

  3. Make sure the data is always held in a stable state during manipulations. There will not be a case of data existing on intermediate stage. Either manipulation is completed or it is aborted. This is done by means of implicit/explicit transactions

  4. Allow parallel process to access the data stored without any concurrent manipulation issues. This is effectively managed through locking determines by isolation level.

  5. Enforces a strict metadata (structure) for the data and can also enforce column level restrictions to make data adhere to business rules like through constraints
