ACID Properties: Relational databases strive to maintain ACID properties for transactions:

Structured Data: Data is organized into tables with rows and columns, adhering to a predefined schema that dictates the data type and constraints for each column.
Relationships: Relationships between tables are established using primary keys (unique identifiers for each row in a table) and foreign keys (columns in one table that reference the primary key of another table). Common relationship types include one-to-one, one-to-many, and many-to-many.
SQL (Structured Query Language): RDBMS are typically accessed and manipulated using SQL, a powerful and standardized language for querying, inserting, updating, and deleting data.


Atomicity: Transactions are treated as a single, indivisible unit. Either all laos whatsapp mobile phone number list changes within a transaction are committed, or none are.
Consistency: Transactions ensure that the database transitions from one valid state to another, adhering to defined rules and constraints.
Isolation: Concurrent transactions are executed in isolation, preventing interference with each other and ensuring data integrity.
Durability: Once a transaction is committed, the changes are permanent and survive system failures.
Normalization: The process of organizing data in a database to reduce redundancy and improve data integrity by dividing larger tables into smaller, linked tables.
