Explore Open-Source Databases on Linux on POWER


Open-source software has transformed the IT landscape, now serving as a core component for clients to produce the next generation of cloud- and analytics-based growth solutions.

Organizations have explored open-source software for three main reasons:

  1. Cost. The less a company spends on proprietary software, the more it can dedicate to other facets of digital transformation efforts.
  2. Open-source databases can be either an alternative to proprietary, commercial databases or a base for brand-new applications that handle specific types of unstructured or semistructured big data
  3. Open-source databases allow companies to derive benefit not only from their own IT employees, or from the employees of proprietary software vendors, but also from the open-source community that supports and grows the core product and ecosystem around these databases

Users tend to group databases into two categories:

  1. Relational: those that are optimized to store and retrieve structured data
  2. NoSQL: those that are optimized to support unstructured data

Most data produced and analyzed today is unstructured, but no single database fits everyone’s needs. Users often take advantage of data stored in multiple databases in a variety of new applications. Enterprise-wide applications are being enhanced to support access to unstructured data and leveraging NoSQL databases.

For anyone interested in exploring open-source database solutions on Linux* on IBM POWER8* technology, MariaDB, EnterpriseDB, Redis, MongoDB and Neo4j are all good starting points. See Figure 1, for more information.

Commercial Relational Databases

Commercial relational databases serve as the backbone of transactional systems, and continue to be enhanced with new functionality and new delivery models such as cloud computing and database as a service. When evaluating any new database, keep in mind that classic transaction atomicity, consistency, isolation and durability (ACID) properties remain a strength in the domain of relational databases.
