One of the most significant differences between the two systems is that the relational database management system(RDBMS) works on a relational database. While Hadoop is a good option in situations where big data processing is required but the data being processed lacks reliable relationships. Let us discuss some more differences between RDBMS and Hadoop with the help of the comparison given below.
What is RDBMS?
RDBMS stands for relational database management system, which is a more sophisticated DBMS system. It originally came to light in the 1970s. Organizations may access data more efficiently with RDBMS systems than with DBMS systems. A software program known as an RDBMS only stores data that must be kept in the form of tables. In this kind of system, data is organized and stored in rows and columns known as tuples and attributes. RDBMS is a powerful data management technology that is widely used across the world.
What is Hadoop?
Hadoop is an open-source software framework used to run applications and store data on a collection of inexpensive hardware. It features a lot of storage space and a strong processor. It has the ability to control several concurrent processes simultaneously. It is utilized in machine learning, data mining, and predictive analysis. Both structured and unstructured forms of data can be handled by it. Compared to traditional RDBMS, it is more adaptable for storing, processing, and managing data. Hadoop, in contrast to the conventional system, enables multiple analytical processes on the same data at once. It offers very flexible scalability support.
RDBMS Vs Hadoop | Difference between RDBMS and Hadoop
- RDBMS is structured data that is mostly processed. Hadoop is both structured and unstructured data processed.
- RDtBMS is best suited for the OLTP environment. Hadoop is best suited for BIG data.
- RDBMS is less scalable than Hadoop, while Hadoop is highly scalable.
- RDBMS stores transformed and aggregated data and Hadoop only stores a huge volume of data.
- Data normalization is required in RDBMS, while data normalization is not required in Hadoop.
- RDBMS has no latency in response. Hadoop has some latency in response.
- RDBMS stores transformed and aggregated data. Hadoop stores a huge volume of data.
- The data schema of RDBMS is static type. Hadoop uses a dynamic data schema model.
- RDBMS is high data integrity available. Hadoop is low data integrity available than RDBMS.
- Cost is applicable for licensed software in RDBMS. Hadoop is free of cost, as it is open-source software.
- Traditional row column-based databases are basically used for data storage manipulation and retrieval in RDBMS. Hadoop is an open-source software used for data and running applications or processes concurrently.
