Difference Between RDBMS and HBase

Data is managed into a database to keep it safe and secure. And then, to manage these databases, a management system is required that is called Database Management System.

RDBMS vs HBase

The difference between RDBMS and HBase RDBMS is way older than the HBase. They both have different requirements, as SQL is required by RDBMS but not by HBase. They also have different natures and schema. HBase has certain advantages over RDBMS as it can handle structured, unstructured, sparse data that cannot be handled by RDBMS. Last but not least, RDBMS also has a disadvantage in terms of data retrieving speed in comparison.

Relational Database Management System is based on a model introduced by E.F.Codd. It secures the related data along with some advantageous features such as security, integrity, consistency, the accuracy of the data.

It has several pros over traditional database systems. It is designed to handles all types (structures, semi-structured, and even unstructured) data.

What is RDBMS?

It is a system that is a collection of programs that help to create and update or any interaction with a relational database.

It also supports multi concert users to use the database along with maintaining the information’s integrity. It supports DBAs that is helpful in monitoring the databases.

Except for all the functions and features it has there are some extra advantages of this such as:

  1. Flexibility: as compared to other systems, the process of updating data is far simpler, as data is not required to be updated in several places; it has to be updated in one place only.
  2. Maintenance: maintenance of data is easier, not this data can also be control without many efforts easily.
  3. Data structure: It is an easier and most effective way of organizing the data. Entering new data is also easier.

What is HBase?

HBase is built on Hadoop and is a column-oriented system. Data is kept in key-value format due to its sets of tables. Columns of any number can be added at any time.

Advantages of HBase

  1. Large data sets: it can store large data, and millions of rows can be added under this system.
  2. Databases breakdown: in a case when relation databases break down, HBase has been the best option.
  3. Fast processing: when compared to any other database, it is faster and more reliable for data reading and processing.
  4. Failover support: it is automatically recovered and has a feature of Region Server Replication.
  5. Scalability: it is supported in both modular, as well as linear forms.
  6. Consistency: it is more consistent in reading and writing data.

Disadvantages of HBase:

  1. There is a possibility of failure in some cases.
  2. It has no support for any transaction.
  3. JOINs cannot be handled in the database itself.
  4. It is only sorted on keys and is indexed.
  5. No built-in authentications.
  6. Unpredictable Latencies
  7. Memory issues on the cluster.

Main Differences Between RDBMS and HBase

  1. Relational Database Management System can only handle the structured data, whereas HBase not only handles the structured data but also handles unstructured as well as semi-structured data.
  2. Relational Database Management System follows, Atomicity, Consistency, Isolation and Durability properties, whereas HBase follows, Consistency, availability, Partition-tolerance theorem.
