18. The 19. 20. is a basic lock that allows any number of transactions to read a 21. tuple, but will not allow any to modify it. Using the terminology of Hadoop and "big data", a single computer in a cluster is called a Hadoop cluster. A ACID can be thought of as a logical unit of work for the DBMS that contains one or more SQL statements that adhere to ACID properties. The SQL statement causes the DBMS to write table changes from working memory onto the disk. This finalizes the changes and makes them permanent. As a general rule, the longer a concurrency protocol holds onto locks, the 2. better (better/worse) the integrity.
