Benefits of Serializability in DBMS Let’s first understand the difference between a serial and non-serial schedule for a better understanding of the benefits that serializability provides. In the case of a ser
even as new rows are inserted. However, the presence of many indexes on a table decreases the performance of updates, deletes, and inserts because Oracle must also update the indexes associated with the table.
In a database management system (DBMS), serializability requires that transactions appear to happen in a particular order, even if they execute concurrently. Transactions that are not serializable may produce incorrect results. There are different types of serializability in DBMS with different advantages...
