Training and experience around MongoDB relates to use of databases in general, and the NoSQL (document-oriented) database MongoDB specifically. Use can cover data modeling, configuration and data management, or some level of application development using the database.

MongoDB is often chosen over traditional databases such as Oracle DB specifically when larger and more unordered datasets are required to be stored and accessed, as NoSQL databases do not suffer the performance drawbacks traditional databases have in this regard. MongoDB is an open source database licensed under the Server Side Public License (SSPL). While popular as one of the earlier available NoSQL databases, MongoDB is nowadays losing ground to its competitors.

MongoDB expertise offers transferable database design skills, especially for other document-oriented databases such as Cassandra. Businesses leveraging or looking to leverage such databases can benefit from individuals with training and/or experience with this technology.

    We need assistance on following issue of commit and rollback transaction process A transaction is a set of database operations (such as reads and writes) that are executed in a sequential order and in an all-or-nothing manner. This means that for the results of running these operations to be saved within the database and visible outside the transaction to other database clients, all of the individual operations must succeed. If any of the operations fail to execute correctly, the transaction aborts and every change made from the beginning of the transaction will be undone. The database will then be restored to its previous state as if the operations never happened. Similar to SQL
