SOLIDATED  I use Aqua Data Studio almost every day. Having switched from a PC last year, I'm on a Mac and this is the only tool available that's both commercially viable and at a reasonable price.

To the reviewers that complain about the $399 price: You guys aren't serious developers. ...Maybe database hobbyists, but no way you guys make a living developing anything. If you did, you'd know just how good a price it actually is. I actually can't think of any other commercial DB software that's cheaper. Can you?

I'm very happy with the available database connection types and options as well as the ease of use. Overall the application is rock solid. My only gripe is that on the Mac (don't know about other versions), I don't like the way windows behave when you're creating or altering a table. The focus of elements isn't what I'd prefer but I can deal with it.

BLEE  I just came back to this software because I needed to do some database work and was shocked to see the price is no $399 thats pretty insane considering all the other options out there including the slew of free tools.  
(Version 6.5.7)

YNOT  Looks cool, but too expensive. If their price jumps $400 in one step, what's the next price increase going to be? Would have liked to continue to recommend this to my hosting clientele, but I am not going to get them into a program that sees such price increases. I would have much rather seen smaller and consistent price increases throughout the life of this product.

NEMESYS  Ouch! What happened here? $399 for a single-user license? Sorry, that's way too expensive for hobbyists.  
(Version 6.0.10)

GERMANO60  Yep, not only it's no longer free but a single license costs $399!!!! OK, nice piece of sw, lots of effort, it's fair to ask money for it. OK, you have full functional version not-expiring for free but that's just for "evaluation purposes".

But going from totally free to $399 in just one shot, well guys, that's maybe one step too much.

What about considering a special discount or a special pricing for single-computer, single-user licensing?

ENNUINI  While a good application, it should be noted that contrary to the information at the time I downloaded Aqua Data Studio, this version marks a changed pricing scheme, and is in fact no longer free.

NADEEMF  Great value (free for academics).

It does the job pretty well when I use it to query Oracle (both from a Mac and from Windows).

Some interactions seem a bit quirky, but it is probably more to do with my ignorance of some Oracle intricacies.

RICHARD  I'm a professional database developer and this is the app I use for practically all my SQL work. I develop for MS SQL server but spend 90% of my time on a Mac. This is really the only app for the Mac that gets it right (I've tried them all and paid several hundred dollars for some of them). If I didn't have this I would have to spend a lot more time on my Windows machine. It's got a combination of features included in the Microsoft tools that ship with SQL server, plus a few that they don't have (like autocomplete of SQL statments, filling in table names and the like). It's intended for developers who know SQL, not casual users who want something to write SQL for them because they don't know how.

It is Java based but performance hasn't been an issue for me (I do most of my development on a dual G5). Note that my high rating in Value is partly because I'm an edu user and it's free for educational use - though I would pay if necessary.  
(Version 4.5.1)

PLANETEN PAULTJE  Pasco.com sells a data aquisition program for its probes called "Data Studio". Could be confusing.......  
(Version 4.5.1)

ANONYMOUS  The feature set is nice but (:::shudder:::) its written in JAVA... YUCK!!!

Not exactly a performance/speed demon...
