Oracle TimesTen vs. PostgreSQL

TimesTen is well suited for applications using smaller data or smaller data stores and where transaction response times are not as business critical. TimesTen is good for applications already accessing Oracle and need to cache data for quick read/write operations. TimesTen is not appropriate for large data dependent applications or applications requiring fast response times. In these cases, using Oracle database or Exadata is better

PostgreSQL is best used for structured data, and best when following relational database design principles. I would not use PostgreSQL for large unstructured data such as video, images, sound files, xml documents, web-pages, especially if these files have their own highly variable, internal structure.

• With basic database experience, TimesTen has a very short learning curve.
• The installation and setup is easy and straightforward. The command line instructions are easy to follow.
• The error logging mechanism is simple and efficient. The system log files are helpful in troubleshooting problems with using TimesTen.
• The maintenance tools are user friendly and effective. Upgrading is easy and quick. TimesTen is almost a self-administrating database.

• It works well with external data sources and runs on platforms with stable performance.
• Clients can rest assured that their personal information will be safe and secure.
• Many forums discuss setup and usage, and most are free.
• Adding tooling applications to a computer is unlimited.
• PostgreSQL runs on many OS platforms and supports ANSI SQL, stored procedures, and triggers.

• Provide better monitoring tools of TimesTen daemon, servers and connections.
• Improved support for APIs. The libraries lack the necessary code for applications to customize for applications using TimesTen.

• Clearer indications on what is the query plan, to optimize the query
• More out of the box, Postgres specific, SQL functions
• It would be nice to have a more visual aid of the relationship between all tables, but possibly this depend more on the UI used

Postgresql is the best tool out there for relational data so I have to give it a high rating when it comes to analytics, data availability and consistency, so on and so forth. SQL is also a relatively consistent language so when it comes to building new tables and loading data in from the OLTP database, there are enough tools where we can perform ETL on a scalable basis.

PostgreSQL's availability is top notch. Apart from connection time-out for an idle user, the database is super reliable.

The data queries are relatively quick for a small to medium sized table. With complex joins, and a wide and deep table however, the performance of the query has room for improvement.

There are several companies that you can contract for technical support, like EnterpriseDB or Percona, both first level in expertise and commitment to the software.

But we do not have contracts with them, we have done all the way from googling to forums, and never have a problem that we cannot resolve or pass around. And for dozens of projects and more than 15 years now.

The online training is request based. Had there been recorded videos available online for potential users to benefit from, I could have rated it higher. The online documentation however is very helpful. The online documentation PDF is downloadable and allows users to pace their own learning. With examples and code snippets, the documentation is great starting point.

The online documentation of the PostgreSQL product is elaborate and takes users step by step.

Sybase does not have an in-memory database until version 15 so TimesTen was ideal for caching data. TimesTen has reliable replication and backing up mechanisms. Oracle takes longer to set up and use for most applications where as TimesTen is a smaller DBMS that is quick and easy to set up and use. TimesTen can connect to Oracle for caching data so using Oracle as a backend makes sense

Although the competition between the different databases is increasingly aggressive in the sense that they provide many improvements, new functionalities, compatibility with complementary components or environments, in some cases it requires that it be followed within the same family of applications that performs the company that develops it and that is not all bad, but being able to adapt or configure different programs, applications or other environments developed by third parties apart is what gives PostgreSQL a certain advantage and this diversification in the components that can be joined with it, is the reason why it is a great option to choose.

• TimesTen has had a positive impact from a developer's perspective because implementing TimesTen is quick and easy. The benefits of TimesTen can be seen almost instantly. For instance, the application start up time is faster, the data is easy to maintain and the performance is fast for TimesTen clients.
• TimesTen has had a positive impact for the business because it can be made accessible to users via a GUI. This gives users transparency to the data at any time.
• The negative impact is that once the TimesTen database has grown too large, the application should move to using Oracle database or else it suffers from performance degradation and stability issues.

• Easy to administer so our DevOps team has only ever used minimal time to setup, tune, and maintain.
• Easy to interface with so our Engineering team has only ever used minimal time to query or modify the database. Getting the data is straightforward, what we do with it is the bigger concern.
• It's free. You can't beat that.
