IBM Db2

Best database for large volume data

Kommentare: We are using IBM db2 to store large volume of sensitive user data which scale automatically when required, it allows multiple concurrent transactions with no data redundancy and maintains the isolation property.

Vorteile:

IBM DB2 provides the low latency and high data availability, It provides automatic scaling and high security for the large volume of data. It is robust No matter how much amount of data is, IBM DB2 will never fail.

Nachteile:

IBM Db2 is a bit expensive and not all the SQL standards available in the IBM Db2

IBM DB2: A high availability Relational Database

Vorteile:

The main project that made me involved in working with DB2 is a transactional concurrency benchmark that compares IBM DB2 to Oracle 10g RDBMS. The benchmark results demonstrated high scalability and availability properties in DB2 but the TPS measures showed a better performance of Oracle 10g on HP ML350 servers. DB2 supported better concurrency in bulk data-intensive SQL queries but lagged in computation-intensive tasks.

Nachteile:

The programming language support is definitely something that needs improvement in addition to cloud integration and deployment tools. Many other commercial RDBMSes (such as Oracle) are leading ahead on this front. OS support, such as testing OS X platforms, can be also better provided in DB2l

IBM D2

Kommentare: I would recommend use of DB2 in modern tech advancements. Light weight DB like MySQL, postgres are much better.

Vorteile:

Db2 was used in our mainframe application. it accepts standard sql syntax. can handle large amount of data.

Nachteile:

As data grows in production environment, it becomes slow. Thread hung and application performance degrades. Also it's costly.

29/5000 Extremely stable and safe

Kommentare: Over 10 years using DB2 I can affirm that it is a very secure bank, with updates that bring new features, high compaction power and geographic contingency features gave us the security to work with SAP.

Vorteile:

DB2 HAS A SERIES OF TOOLS THAT ARE DIFFERENTIAL, BUT HIGHLIGHTING THE CAPACITY OF SELF-MANAGEMENT (PARAMETERIZATION) AND DATA COMPACTION. ARE STRONG POINTS TO CONSIDER.

Nachteile:

The acquisition cost can be a hindrance in the acquisition negotiations. Support is also a weakness for the cost, forcing the use of DB2 communities for troubleshooting.

Heavy and expensive, but good at what it does

Vorteile:

Db2 scales very well AFTER a certain point. Support is excellent, it's easy to get stood up once you have a feel for what you're doing.

Nachteile:

Scaling: for instance it won't run on small machines too well. This becomes important if you're running a local copy for development or testing. There is a free Community Edition to play with, but can't take advantage of tons of ram or CPU, but good for POC.
