5 Best Big Data Databases

Top 5 Big Data Databases - ScienceSoft

With 8 years in big data services, ScienceSoft assists companies with selecting and implementing proper software for their big data initiatives.

Big Data Databases: the Essence

Big data databases store petabytes of unstructured, semi-structured and structured data without rigid schemas. They are mostly NoSQL (non-relational) databases built on a horizontal architecture, which enable quick and cost-effective processing of large volumes of big data as well as multiple concurrent queries.

Examples

Even though non-relational databases have proved to be better for high-performance and agile processing of data at scale, such solutions as Amazon Redshift and Azure Synapse Analytics are now optimized for querying massive data sets, which makes them sufficient when dealing with big data.

Big Data Architecture and the Place of Big Data Databases in It

Big data architecture may include the following components:

  • Data sources – relational databases, files (e.g., web server log files) produced by applications, real-time data produced by IoT devices.
  • Big data storage – NoSQL databases for storing high data volumes of different types before filtering, aggregating and preparing data for analysis.
  • Real-time message ingestion store – to capture and store real-time messages for stream processing.
  • Analytical data store – relational databases for preparing and structuring big data for further analytical querying.
  • Big data analytics and reporting, which may include OLAP cubes, ML tools, self-service BI tools, etc. – to provide big data insights to end users.
