IBM DB2 experience
What do you like best about the product?
The ease of organizing & managing data. But it has been a long while I have worked on DB2. But I like using the SQL commands.

Recommendations to others considering the product:
It's a great product with relatively easy commands to help get the job done. But since it's been a while that I've been exposed to it I can't tell you other specifics or improvements that were done.

Strong points and weak points IBM Db2
What do you like best about the product?
DB2 is a robust database and is supported by a large company like IBM. The positive points are: reliability, excellent transaction control and high availability. The database that is used by the manager has the database recovery option enabled, by default. This allows recovery of the database in the event of a system failure. By enabling the recovery option, DB2 will generate transaction logs and save them to a DB2 system directory. Over time, these logs will increase in size. The recommended way to free up space is to use the DB2 userexit function, as described in the DB2 Administration Guide. Another way to free up space on the file system is to move the inactive logs to another file system. This method is described below. To move the inactive logs to another file system, follow the steps below.
What do you dislike about the product?
DB2 should not be used for small projects and companies with little infrastructure. Another negative point would be the "weight" in the servers. Relational database of the giant IBM, DB2 does not have such a large share of the market, although it is quite robust and executable on several platforms. Used for large systems, it is optimized to work with the manufacturer's own hardware. Probably, licensing issues and business models established for it have disadvantaged its spread in recent years.

I used DB2 in a project for the financial area, in which I needed high availability and reliability in transactions.
