What is a Distributed Database?
FAQs
What is a distributed database?
A distributed database is a database system that stores data in multiple locations instead of one location. This means that rather than putting all data on one server or on one computer, data is placed on multiple servers or in a cluster of computers consisting of individual nodes. These nodes are oftentimes geographically separate and may be physical computers or virtual machines within a cloud database.
What are the two types of distributed databases?
The two types of distributed databases are homogeneous distributed databases and heterogeneous distributed databases. In homogeneous distributed databases, all machines across multiple sites in the distributed database share the same exact data, data model, operating system, and the same distributed database management system. Meanwhile, in a heterogeneous distributed database, different machines may house different data sets, use different operating systems, contain different data schemas, and require software to facilitate communication between machines.
What are the ACID properties?
The ACID properties consist of four elements:
- Atomicity: Atomicity means that a transaction is treated as a single unit.
- Consistency: Distributed database systems maintain data consistency by enforcing predefined rules and data constraints.
- Isolation: Each transaction is isolated from the other transactions to prevent data conflicts and maintain data integrity.
- Durability: Durability ensures that stored data is preserved in the event of a system failure.
What are some types of database replication?
Types of database replication include full replication, transactional replication, snapshot replication, partial replication, and merge replication.
What are different types of continuous failure monitoring in distributed database systems?
Different types of continuous failure monitoring include:
- Heartbeating.
- Watchdog timers.
- Data checksums.
