I use the tool mainly for administration of DB2 z/OS and LUW installations of various release levels. Navigation is very intuitive and super fast. Best I ever experienced with DB2. The many text and SQL generation tools are a great help. The Compare feature is amazingly flexible. Apart from the task of setting Automatic Maintenance (like maintenance window, task scheduler) or extensive mainframe schema change, the tool brings all what I need for my day-to-day tasks, and that has been true for the last 15 years. And if you miss something, or if you spot a flaw in the display or catalog queries, you simply write a mail to the AQT team and they fix it within a few days, or you fix it yourself in the configuration file (which is open and easy to understand). I love the feature that opens a session with the database host to run DB2 commands.

We have been using AQT at my company for many years, mainly with DB2 z/OS - but with many other databases as well. Hands down it beats all other SQL tools, and its abilities to manage tables, views, table spaces, indexes and other objects in DB2 REALLY put it a cut above. Search around for SQL/database Tools for DB2 z/OS ans see what you find from anyone other than IBM - you wont find much at all. And IBM itself has nothing to compare. Even if used as a pure SQL query tool, its abilities to manipulate the data AFTER you retrieve it from the database are amazing. It also has one fo thebest interfaces with Excel, to output the data, that I have seen. No, I am not being paid to write this! We have over 300 people using AQT and wouldn't trade it for anything.

I have been using AQT for over 10 years now, and I prefer it over the other bloated tools on the market, including IBM's and Oracle's own products to connect to their own databases. AQT can connect to most of the RDBMS's and presents a familiar interface, so you don't have to worry about losing functionality between databases. Their customer service is also fast and reliable.
