EDB Postgres Advanced Server vs. Tibero

Very well suited to applications mixing relational with NoSQL and/or complex data types, such as network analysis, JSON, key-value-pair, etc. Excellent if you have multiple programming languages in use (Python, Perl, R, etc.) because PPAS supports so many languages natively. Not well suited if you need encryption at rest, compressed data or very large database-tier backups. [Large backups should be done at the storage tier if possible.]

It's a good choice when it comes to switching to a lower but similarly stable and scalable database solution. For any enterprise that needs a robust set of features when choosing a database vendor you have a few choices, paid (expensive or lower cost) or open source. Depending on your needs Tibero might be a good fit.

• PPAS Oracle compatibility, especially the PL/SQL syntax, has made migrating database-tier code very simple. Most Oracle packages do not need to be changed at all and those that do are generally for simple reasons like a reserved word in PPAS that is allowed in Oracle.
• PPAS xDB, the multi-master replication tool, is simple and - most important - does not break with network or other interruptions. We have been able to configure and forget, which our customers could never do with other multi-master tools.
• Most people had no idea that PPAS and PostgreSQL have full CRUD support for JSON. They think you need a specialized product and/or that JSON is read-only. Every organization that I have worked with is evaluating adding JSON to their relational model.

• Robustness
• Feature set

• Documentation is excellent but spread out across many resources and can take a while to wade through—would benefit from having more intro level, getting started guides for various languages.
• Ruby support is excellent but more Ruby examples and beginner-level documentation would be nice.
• It is sometimes hard to find a community of users on StackOverflow so a larger community, and a dedicated forum with active members to answer questions and work through issues would be nice.

• Working with Tibero for the last 5 years, I haven't noticed any issues so far.

We chose Postgres Plus Advanced Server because we had the finances to do so and needed the robust featureset, along with the power to optimize our performance and integrate with the development tools of our choosing. We audited a number of options, exploring potential solutions at various levels of robustness and decided that this was our best option moving forward.

I know Oracle, IBM's DB2, and Microsoft SQL Server are also commonly used DBMSs. We selected Tibero, because unlike DB2 and SQL Server, it is fully SQL compliant and therefore switching away from Oracle was very low risk for us despite never using Tibero before. We knew that worst case, we just go back to Oracle. However, after using Tibero, we realized it just makes more sense for us financially. Why pay for something more? It is identical to Oracle and claims to have better security. So far no problems.

• Postgres Plus Advanced Server is quite complex and may take longer to implement certain things than simply using PostgreSQL depending on developer familiarity with the platform.
• Getting up to speed can be daunting so again, there is an upfront cost in time spent learning the platform, besides the potential for extra time spent on a feature-by-feature basis.
• The cost of Postgres Plus Advanced Server should be weighed against simply using PostgreSQL to decide which is the best solution for your business needs.

• Because Tibero's licensing and support fees are half of Oracle's, we were able to allocate the extra budget to other departments that were in greater need for those funds.
