What is meant by database interaction?

Database interaction refers to the process of communicating with a database to perform operations like creating, reading, updating, and deleting data.

In the realm of computer science, database interaction is a fundamental concept that involves the exchange of information between a user or an application and a database. This interaction is facilitated through a database management system (DBMS), which serves as an interface between the database and the user or application. The DBMS ensures that the data is stored and retrieved in a secure, efficient, and reliable manner.

The interaction with a database typically involves executing structured query language (SQL) commands. SQL is a standard language for managing and manipulating databases. It includes commands for creating tables, inserting data, updating data, deleting data, and querying data. For example, a user might interact with a database by executing an SQL command to retrieve data from a table, update a record, or delete a record.

Database interaction is not limited to SQL commands. It also involves the use of transactions, which are sequences of operations that are executed as a single unit of work. Transactions ensure that the database remains in a consistent state even in the event of failures. They follow the ACID properties, which stand for Atomicity, Consistency, Isolation, and Durability.

Furthermore, database interaction can also involve the use of stored procedures and triggers. Stored procedures are precompiled collections of SQL statements that are stored in the database. They can be invoked by applications to perform repetitive tasks. Triggers, on the other hand, are special types of stored procedures that are automatically executed in response to certain events on a particular table or view in a database.

In summary, database interaction is a crucial aspect of managing and manipulating data in a database. It involves executing SQL commands, using transactions, and utilising stored procedures and triggers. The goal is to ensure that data is stored and retrieved in a secure, efficient, and reliable manner.
