DB2

DB2 is suitable for any use. The main one is certainly the creation of an online database that can be queried online through TP queries and through batch reports. It is necessary to take care of the database maintenance to allow maximum performance, for this, there are the utilities that help the system operators to do it.

PostgreSQL

PostgreSQL is ideal for handling databases that contain large volumes of information due to its efficiency, speed and above all because of the good management it makes of our resources, it also behaves very well in distributed environments of high demand, if you want a database of stable data and excellent performance PostgreSQL is one of the best.

Pros

DB2

  • DB2 maintains itself very well. The Task Scheduler component of DB2 allows for statistics gathering and reorganization of indexes and tables without user interaction or without specific knowledge of cron or Windows Task Scheduler / Scheduled jobs.
  • Its use of ASYNC, NEARSYNC, and SYNC HADR (High Availability Disaster Recovery ) models gives you a range of options for maintaining a very high uptime ratio. Failover from PRIMARY to SECONDARY becomes very easy with just a single command or windowed mouse click.
  • Task Scheduler ( DB2 9.7 and earlier ) allows for jobs to be run within other jobs, and exit and error codes can define what other jobs are run. This allows for ease of maintenance without third party softwares.
  • Tablespace usage and automatic storage help keep your data segmented while at rest, making partitioning easier.
  • Ability to run commands via CLI (Command Line Interface) or via Control Center / Data Studio ( DB2 10.x+) makes administration a breeze.

PostgreSQL

  • Reliability - There is absolutely no issue with uptime or data integrity.
  • Flexibility - The wide range of data types which are supported gives us immense flexibility in terms of what data we can store.
  • Speed - Even at our busiest, we are able to count on the performance of the engine matching our needs.
  • Internal features - Thanks to the wealth of internal features, we have less external dependencies to perform common business tasks.

Cons

DB2

  • IBM is really behind in delivering developer tools. They pride themselves on Data Studio, but it is just frustrating.
  • Marketing. Horrible to do a Google search and get returns for a COMPLETELY different product, for z/os. Why they share the same name is beyond me. Better marketing would also increase the user base and help the product mature.
  • Slower than the competition to roll out next-generation features.

PostgreSQL

  • The performance of PostgreSQL has been enhanced through the years, but always is better to have as much performance as we can.
  • The replication services could be done directly within the database, and more easily.
  • The Object Orientation of the Database could be extended, and albeit it manages inheritance of tables, and accepts XML and JSON as primary types, it would be wonderful if one could attach methods more easily to tables (to make them more like classes), and instances (rows for example).

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.

DB2 for i is extremely stable. I've experienced system slowdowns and performance issues on badly configured systems or badly configured system accessing the DB but that's it, never had a problem caused purely by the software. Support is also pretty good.

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

Performance

DB2

DB2 9.9
Based on 20 answers
The performances are exceptional if you take care to maintain the database. It is a very powerful tool and at the same time very easy to use. In our installation, we expect a DB machine on the mainframe with access to the database through ODBC connectors directly from branch servers, with fabulous end users experience.

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.

AWS, Heroku, and Digital Ocean all provide Postgres-as-a-service, where you pretty much never need to administrate it yourself but they do it for you. The Postgres community also has developed awesome and reasonably priced extensions, such as Citus DB and CockroachDB in case you need additional support for running it. If you need documentation, Postgres's docs are super thorough and their official forms are active.

Online Training

DB2

PostgreSQL

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.

Alternatives Considered

DB2

DB2 is a similar product that is most respected. Oracle might be supported in a broader context, but DB2 is superior on every platform where the choice is there. Licensing is also a factor in which DB2 is much better, which might offset any cost differences. DB2 support is also much better at all tiers.

Postgres stacks up just [fine] along the other big players in the RDBMS world. It's very popular for a reason. It's very close to MySQL in terms of cost and features - I'd pick either solution and be just as happy. Compared to Oracle it is a MUCH cheaper solution that is just as usable.

It can grow as your company grows. It also plays well with Crystal Reports and other BI software once you create an ODBC connection for the DB. It can be managed with SQL management studio so no extra software is needed for that.

Return on Investment

DB2

  • Positive - Very good performance as compared to other traditional DBs.
  • Positive - Transaction and query search are made easy from a DB level with good performance, also runs on top scape on AIX servers.
  • Negative - There is always room for improvement, such as Webex queries and the GUI base tool. Also the available support documentation should be improved.
Pradeep Bele | TrustRadius Reviewer

PostgreSQL

  • By pushing a lot of logic into database views and triggers, PostgreSQL provides the ability to write much slimmer and more maintainable controller code, reducing development costs.
  • PostgreSQL's upsert capabilities enabled us to go to scale much more easily and quickly, allowing us to increase our number of customers.
