ACID refers to the basic properties of a database transaction: Atomicity, Consistency, Isolation, and Durability. All Oracle database, Oracle RDB and InnoDB transactions comply with these properties.. Apart from these ACID properties, there are some basic characteristics due to which Relational DBMS become popular. Some of them are: Some of them are: Data is stored in a set of Tables or data is stored in the format of row and column in a table.).

Acids and bases are two types of corrosive substances. Any substance with a pH value between 0 up to 7 is considered acidic, whereas a pH value of 7 to 14 is a base. Acids are ionic compounds that break apart in water to form a hydrogen ion (H+). Ionic compounds are a compound with a positive or negative charge. Bases, on the other hand are ionic compounds that break apart to Transactions -ACID CS 317/387 2 Transactions Many enterprises use databases to store information about their state e.g., Balances of all depositors at a bank When an event occurs in the real world that changes the state of the enterprise, a program is executed to change the database state in a corresponding way e.g., Bank balance must be updated when deposit is made Such a program is …

For example, a transfer of money from one bank account to another requires two changes to the database both must succeed or fail together. You are working on a system for a bank. A customer goes to the ATM and instructs it to transfer Rs. 1000 from savings to a checking account.
