In the highly competitive industry of enterprise database management systems and tools, most systems come packed with features from hot backups, disaster recovery, high-availability to extensive cloud services. These database systems range in price from free(open source) to tens of thousands of dollars. There’s no single correct answer for every data problem. Neither is there a perfect database system; each has its own set of features and shortcomings and generally fulfills a specific need. Below is a list top enterprise database systems on the market in 2015 to help you determine which solution will likely work best for you.

1. Oracle



Oracle has been a leading Enterprise database for decades and it’s still leading the race. It began its journey in 1979 as the first commercially available relational database management system (RDBMS). Oracle’s name is synonymous with enterprise database systems, unbreakable data delivery and fierce corporate competition from CEO Larry Ellison. Powerful but complex database solutions are the mainstay of this Fortune 500 company. The current release of Oracle’s RDBMS is Oracle 12c. The “c” stands for cloud and is reflective of Oracle’s work in extending its enterprise RDBMS to enable firms to consolidate and manage databases as cloud services when needed via Oracle’s multitenant architecture and in-memory data processing as well as recognizing the competition and the shift towards cloud systems.

2. SQL Server



Microsoft is undergoing a lot of changes in recent times, whilst it’s marketshare has reduced, its profitability exceeds all other tech companies, and SQL Server helped put it there. Sure, Microsoft’s desktop operating system is everywhere, but if you’re running a Microsoft Server, you’re likely running SQL Server on it. SQL Server’s ease of use, availability and tight Windows operating system integration makes it an easy choice for firms that choose Microsoft products for their enterprises.

Currently, Microsoft promotes SQL Server 2014 as the platform for both on-premises and cloud databases and business intelligence solutions. Microsoft also touts SQL Server 2014 in helping enterprises build mission-critical applications with high-performance, in-memory security technology across OLTP (online transaction processing), data warehousing, business intelligence and analytics.

3. IBM DB2



Big Blue puts the big into data centers with DB2. The latest release of DB2, DB2 10.5, runs on Linux, UNIX, Windows, the IBM iSeries and mainframes. IBM has pitted its DB2 system squarely in competition with Oracle’s, via the International Technology Group, and the results showed significant cost savings for those that migrate to DB2 from Oracle. How significant? How does 34 percent to 39 percent for comparative installations over a three-year period sound? IBM DB2 10.5, or the DB2 “Cancun Release,” is also the only database fully optimized for the IBM Power Systems POWER8 processor and the company’s Power 8 server systems.

4. SAP Sybase ASE SAP Sybase SAE



Sybase is still a major force in the enterprise market after 25 years of success and improvements to its Adaptive Server Enterprise product. Although its market share dwindled for a few years, it has seen a bump in the next-generation transaction processing space following being acquired by Sybase in 2010 and relabeled as SAP Sybase Adaptive Server Enterprise (ASE). Sybase has also thrown a considerable amount of weight behind the mobile enterprise by delivering partnered solutions to the mobile device market.

5. PostgreSQL



PostgreSQL, generally just called Postgres, is an open-source object-relational database management system (ORDBMS) that hides in such interesting places as online gaming applications, data center automation suites and domain registries.

PostgreSQL also enjoys some high-profile duties at Skype and Yahoo! PostgreSQL is in so many strange and obscure places that it sometimes referred to as the, “Best Kept Enterprise Database Secret.” PostgreSQL’s current stable release is 9.4.x. PostgreSQL runs on a wide variety of operating systems, including Linux, Windows, FreeBSD and Solaris. And as of OS X 10.7 Lion, Mac OS X features PostgreSQL as its standard default database in the server edition.

PostgreSQL benefits from more than 25 years of development as a free, open-source database system, and it includes enterprise-grade features comparable to Oracle and DB2 such as full ACID compliance for transaction reliability and Multi-Version Concurrency Control for supporting high concurrent loads.

6. MariaDB Enterprise



MariaDB Enterprise is a fully open source database system, with all code released under GPL, LGPL or BSD. MariaDB originated in 2009 as a community-driven fork of the MySQL RDBMS and is led by the original developers of MySQL, who created the fork following concerns over MySQL’s acquisition by Oracle. The current stable series of MariaDB Enterprise is powered by MariaDB 10.x.

MariaDB has seen its popularity explode recently at the expense of MySQL, particularly in its support by popular Linux distributions. In 2013 alone, Red Hat Enterprise Linux (RHEL) ditched MySQL for MariaDB, Fedora opted for MariaDB over MySQL in its Fedora 19 release, and both openSUSE and Slackware Linux made similar switches to MariaDB over MySQL. Wikipedia also adopted MariaDB over MySQL as its backend database in 2013. Another key factor in moving MariaDB ahead of MySQL is its enhanced query optimizer and other performance-related improvements, which give the database system a noticeable edge in overall performance compared to MySQL.

7. MongoDB Enterprise



MongoDB (from humongous) is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster. Released under a combination of the GNU Affero General Public License and the Apache License, MongoDB is free and open-source software.

MongoDB is monitored and administered through the MongoDB Management Service (MMS), and the vendor is introducing backup and point-in-time recovery improvements with the 2.6 release. On the horizon is a wave of MMS automation features that will see public beta release in May. Automation will enable administrators to launch instances without coding and manage and upgrade existing deployments without taking them offline. Automated cloud support will start with Amazon EC2, but MongoDB plans to add OpenStack and IBM SoftLayer virtualization options. The automation features are expected to reach general availability within calendar year 2014.

8. Apache Cassandra



Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters,[1] with asynchronous masterless replication allowing low latency operations for all clients.

The open source Apache Cassandra NoSQL database has quickly become the preferred data management platform for Web, Mobile, and IoT applications that need to scale and perform in distributed environments that consist of multiple data centers and/or clouds.

Cassandra’s masterless, shared nothing architecture provides enterprises with constant uptime for their transactional/operational database applications as well as a flexible data model capable of storing today’s modern datatypes and operational simplicity for easy database management.
