Popular ACID-compliant databases include all SQL engines (Oracle, MySQL, PostgreSQL, and MS SQL server are a few examples), Neo4j, and MongoDB. You can usually find out if a database is ACID-compliant by searching the database’s website for a statement on ACID compliance. ACID properties...
Starting Version 0.14, Hive supports all ACID properties which enable us to use transactions, create transactional tables, and run queries like Insert, Update, and Delete on tables. In this article, I will explain how to enable and disable ACID Transactions Manager, create a transactional table, ...

This variability can also be attributed to the undulating terrain and non-uniform management of fallow land with degraded vegetation cover, leading to visible differences in surface soil properties over short distances. For both maps, the northern hilly region indicated a higher level of soil NO3...
