Big Data Databases: the Essence

Big data is multi-source, massive-volume data of different nature (structured, semi-structured, and unstructured) that requires a special approach to storage and processing.

The distinctive feature of big data databases is the absence of rigid schemas and the ability to store petabytes of data. NoSQL (non-relational) database systems are optimized for big data. They are built on a horizontal architecture and enable quick and cost-effective processing of large data volumes and 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.

*What is your industry?

*What data will be stored in your big data database?

?

Different big data databases are optimal for different types of data. This is the most important factor.

*How would you describe the structure of your data?

*What will be the main functions of your big data database?

*What is your current/expected data volume?

?

If you do not know your data size in TB, describe it as a number of data records, e.g., sensor readings, transactions, orders, payments, etc. in comments.

*How much do you expect your data volume to grow in the next 12 months?

*What are your data backup needs?

*Has your company been using any cloud services so far?

*Do you have any compliance requirements?

?

There is specificity in how different big data databases support compliance requirements.

Do you already have a database you want to migrate data from?
