Five types of Transaction processing system?
Types[edit]Contrasted with batch processingBatch processing is not transaction processing. Batch processing involves processing several transactions at the same time, and the results of each transaction are not immediately available when the transaction is being entered;[1]there is a time delay. Transactions are accumulated for a certain period (say for day) where updates are made especially after work.[edit]Real-time and batch processingThere are a number of differences between real-time and batch processing. These are outlined below:Each transaction in real-time processing is unique. It is not part of a group of transactions, even though those transactions are processed in the same manner. Transactions in real-time processing are stand-alone both in the entry to the system and also in the handling of output.Real-time processing requires the master file to be available more often for updating and reference than batch processing. The database is not accessible all of the time for batch processing.Real-time processing has fewer errors than batch processing, as transaction data is validated and entered immediately. With batch processing, the data is organised and stored before the master file is updated. Errors can occur during these steps.Infrequent errors may occur in real-time processing; however, they are often tolerated. It is not practical to shut down the system for infrequent errors.More computer operators are required in real-time processing, as the operations are not centralised. It is more difficult to maintain a real-time processing system than a batch processing system.

What four main types of action are involved in database briefly discuss each?
Defining a database involves specifying the data types, structures, and constraints for the data to be stored in the database. Constructing the database is the process of storing the data itself on some storage medium that is controlled by the DBMS. Manipulating a database includes such functions as querying the database to retrieve specific data, updating the database to reflect changes in the miniworld, and generating reports from the data. Sharing a database allows multiple users and programs to access the database concurrently.
What do you understand by the terms atomicity durability isolation and seralizability applied to transactions?
Transactions has four key properties that are abbreviated ACID.ACID is an acronym for atomic consistent isolated durability. Atomic means that all the work in the transaction is treated as a single unit. Either it is all performed or none of it is. consistent means that the transaction leaves the database in a consistent internal state. Isolation means that the transaction sees the database in a consistent state. This transaction operates an a consistent view of the data. if two transactions try to update the same table, one will go first and then other will follow .durability means that the results of the transaction are permanently stored in the systems.
Difference between a local procedure and stored procedure?
local procedure wont store in database. Stored procedure store in database permanently and we can use it whenever we require. Other program also can use this stored procedure. And the transaction of stored procedure take care by DBA. But the local procedure transaction is take care by manually only
Why database integrity?
Database integrity ensures that data stored in the database is accurate and reliable. It helps prevent data corruption, inconsistencies, and errors by enforcing rules and constraints. Maintaining database integrity ensures that the information remains trustworthy and can be relied upon for decision-making processes.

How does two phase commit process work in distributed database?
Pretty much the same way it works in any type of architecture. If it's distributed it just means it can span multiple databases of different types. Database changes required by a transaction are initially stored temporarily by each database. The transaction monitor then issues a "pre-commit" command to each database which requires an acknowledgement. If the monitor receives the appropriate response from each database, the monitor issues the "commit" command, which causes all databases to simultaneously make the transaction changes permanent.
