NDBDAT

NDBDAT is a data access technology developed by MySQL AB, now part of Oracle Corporation. It is designed to provide high availability and scalability for database applications. NDBDAT is based on the NDB Cluster, a distributed, shared-nothing, and highly available database system. It supports both SQL and NoSQL data models, making it versatile for various types of applications.

The architecture of NDBDAT is built around a cluster of nodes, each running a copy of the NDB storage engine. This allows for data replication and distribution across multiple nodes, ensuring data redundancy and fault tolerance. The system uses a shared-nothing architecture, meaning each node operates independently and communicates with others through message passing.

NDBDAT supports ACID (Atomicity, Consistency, Isolation, Durability) transactions, ensuring data integrity and reliability. It also provides features such as automatic failover, load balancing, and dynamic reconfiguration, which contribute to its high availability and scalability.

The technology is designed to handle large volumes of data and high transaction rates, making it suitable for applications that require real-time data processing and analysis. It is commonly used in scenarios where uptime and data consistency are critical, such as in financial services, telecommunications, and e-commerce.

NDBDAT integrates seamlessly with other MySQL products, allowing developers to leverage its capabilities within existing MySQL environments. It is also compatible with various programming languages and development frameworks, providing flexibility in application development.
