I'm looking for som testing programs for a firebird db server, to stress-test and find bottlenecks.
Something like DB-Optimizer, only for firebird would be nice.
Can also be separate programs, one for stress-testing and one for profiling.
You may look :
sinatica monitor
IBSurgeon tools
IBExpert
and you can also just request monitoring tables (Firebird 2.1)
Just complementing Hugues answer:
Sinatica monitor uses monitoring tables from Firebird 2.1, so will not work very well on FB2.0 or below.
IBExpert have his own type of monitoring tables to help you in this task.
If you are using FB 2.5 you can look also Firebird Trace Manager.
To make some stress tests using your own application you can always look for AutoHotkey. Just be careful... Sometimes you can really mess things with it.
Jmeter may work rather well, as it's fairly easy to setup a basic DB request test, and can be incredibly flexible.
Overview
Manual
You may look at Firebird profiler to trace the queries

In HTML+CSS+JS world, http://jsfiddle.net/ is very helpful tool for asking / making example about web development. And I also saw several browser(javascript)-based programming language compilers and REPLs. But I can't find online / web-based test environment for database operations( especially for RDBMS ).
Is there any open/free database service with web-based interfaces for testing queries?
Added: This tool will be good for this situation; If I'm troubling with complex queries, then create a sample table via web interface and ask it on stackoverflow with the 'sample table URL'. Anyone can access to the URL and test their queries on web site. (Yes, queries are running on 'real' database system) And also the query results can be tracked, then we can even make 'ranking' for it :)
Try SQL Fiddle.
You can try your SQL query and execute/test it.
There are free "disposable" database servers like db4free and even MonoQL.
As far as the web-based interfaces and short URLs go, I don't think you'll have much luck.
To manage your data you have to stick to what is provided (usually phpMyAdmin or similar) and there is no short-URL to query mapping. One other caveat of such system is that (without the appropriate user permissions) one user could easily destroy all your test data -- and remember that (relational) database versioning is much more expensive than plain text versioning, so that's pretty much out of the question.
For non-RDBMS, I can think of try.mongodb.org -- but it suffers from the same problems.
Almost forgot, the Stack Exchange Data Explorer, lets you practice T-SQL queries (with permalinks).
PS: As a personal side-note, I think it's a cool idea and I would love to see something like that implemented, perhaps even mashed-up with SchemaBank or similar - that would be just awesome.
You can't really test a query without the right underlying dbms, schemas (or databases), tables, constraints, stored procedures, and permissions, which tend to be highly application specific. (That is, not readily reusable among multiple users.)
Instead, the database world has grown up into database management systems that you can freely download and install locally. Then you can build and populate your own tables, and test your queries however you like.
Most of these come with both a command line interface and some kind of graphical interface. It's not clear to me what a web-based interface would give you that doesn't already exist in one form or another.
I think that, to do what you want, would require commercial licenses for Oracle, DB2, SQL Server, and Sybase. That's a pretty high barrier to entry for a free web site.
Trouble with a web based query analyser is that you'd need to let it 'tunnel' on to your box to run the queries and for many making a development/test box open to the internet is not a possibility.
For a non web based tool you could look at LinqPad http://www.linqpad.net/ - it does Linq & Sql and other stuff too - very handy tool indeed
We're currently using VincentVega (now rolled into Tarantino) for our database CI. We're using CruiseControl.Net for our web app (C# using TFS).
VincentVega has worked out relatively well since it's very explicity and handles the two scenarios of create and update (while preserving existing data) equally well. I'm looking into upgrading to Tarantino, but I'd like to know if anyone might suggest some alternatives I should look into? Tools like SQL Compare that "automagically" produce delta scripts are out of the question, unfortunately, since our database is highly normalized with over 500 tables.
Thanks

There is also another project which may be worth looking at by Rob Reynolds; RoundHousE
http://code.google.com/p/roundhouse/
The wiki is at https://github.com/chucknorris/roundhouse/wiki
There's a similar tool by Paul Stovell and friends called DbUp.
One notable difference between Tarantino and DbUp is that while Tarantino is typically called from a build script (like Nant or msbuild), DbUp has .NET classes you use within your application. This potentially allows for better fallback handling in case a script doesn't go as planned.
http://code.google.com/p/dbup/
Here's the original announcement of DbUp from Paul Stovell's blog:

I think it might be of interest to post another answer since Redgate now has a new offering, ReadyRoll, that satisfies your key concerns.
"it [SQL Compare] just doesn't put together a synch script correctly"
Yes, diffing tools can sometimes get the script wrong. Often it's not that the script doesn't work, but it doesn't apply the change in the desired way. ReadyRoll's best-of-both-worlds approach uses SQL Compare under the hood to create each migration script, but crucially it allows the developer to customize the script afterwards.
"RoundHousE and tools like it already operate in a model similar to what we're doing now"
ReadyRoll's approach is, like RoundHousE, migrations-based, managing the upgrade process by running a series of consecutive scripts. This tool was built in recognition that many development teams prefer working this way.
"One last reason for choosing RoundHousE: Chuck Norris"
I will have to concede defeat on this point...
Does anyone know if it's good solution to use SQLite in multi-thread environment.
I want to replace SQL Server with more simple and built-in database as there is no need to feed such big server DB. The supposed max size of DB would be 4 gigabyte after 4-5 years of usage. Is it normal for built-in DB? Could it affect performance?
It depends on the type of queries you would use. If the queries are simple selects with plain joins, then SQLite could do fine but I think you would still be better off with e. g. Firebird 2.5 when the stable release gets out (RC3 is available now). You would have somewhat richer SQL to work with. I don't know how much bulk loads are important for you, but neither SQLite nor Firebird are very strong in this area. If you need good bulk insert performance and low cost, then you should look at PostgreSQL or MySQL. There is also a very interesting looking database I happened to stumble upon recently called CUBRID. I have only installed it so far, so I can't tell how good or bad it is but it certainly seems worth a look.
You might also want to look at this wikipedia article:
http://en.wikipedia.org/wiki/Comparison_of_relational_database_management_systems
I don't know which distro you're talking about here. I've only used SQLite.NET and I know it works well on multithreaded applications.
It can also be deployed on client-server systems so you need not worry at all.
Considering Vinko's statement of 'real' databases, you can ignore him. SQLite is really worth it's salt.
If you're working with .NET, you might find this link useful:
http://sqlite.phxsoftware.com
According to the documentation SQLite is thread safe but there are caveats.
You can use SQLite in a multithreaded environment, but if and only if you build a special version of it (and find out if the library you'll be using it supports it and tweak it if it doesn't.) So, assuming your library supports multithreaded SQLite, if you really need a high level of concurrency to the database you may prefer to use a 'real' database. Be it MSSQL or any other falls out of the scope of the question.
Consider MySQL and SQL Server Express, for example.
If your concurrency level is low, SQLite can cope with it.
I would also suggest you to take a look at the CUBRID database. It has nice optimizations for Web applications and it is easy to learn.
Can someone recommend a great IDE/Database Developer Tool for Postgres 8.4. We are currently using EMS SQL Manager but it has so many bugs and shortcomings that its getting on my nerves. I reported the bugs to EMS but they have not been fixed yet.
I wonder what do people use for PostgresSQL development? Windows/Linux, commercial/free, standalone/eclipse plug-in, it does not matter as much. I just want a reliable tool that works and does not blow up in my face.
On PostgreSQL DB we do and would like to have IDE support for.
Tables, views, indexes, triggers
SQL, plpgsql, and python procedures that return single values, set of values or tables
SQL query and performance monitoring
DB role management
Good transaction support straight from GUI as well as support for BEGIN, COMMIT, etc
Any recommendations are welcome.
Edit: After many months we are still using EMS SQL Manager. I got used to certain shortcomings, some bug were fixed. I tried every possible PostgreSQL management program I could get my hands on and still in my opinion EMS SQL Manager is still the best.
pgAdmin is a popular one. It's free, and it runs on Windows and Linux. It's been a while since I have used it but I found it to be quite stable. Wasn't fond of the procedure code editor - it worked, I just didn't like it (but now I can't remember why, it was probably a minor thing).
Lightning Admin, commercial, postgreSQL and mysql, $50. The developer is very pro postgreSQL.

There are many options for editing and writing Stored Procedures in Oracle; what is the best tool for you and why? (one tool per answer.)
Tool for Oracle Application Developers (TOAD), from Quest Software (formerly TOADSoft) has an excellent Stored Procedure editor with syntax highlighting, some autocomplete support (e.g. type in 'TABLE.' and the columns will appear), a nice Execute Procedure option that will show the results in a Grid or show DBMS output, and will also focus on syntax errors when you hit compile.
Note: The Freeware edition only allows 2 concurrent connections to the same Database Instance (even though the website says 5) - that means only 2 developers or DBA's can use it at the same time on the same Database. It also expires every 3 months but they're good at releasing updates.
I recently found the free Oracle SQL Developer.
nice looking GUI (makes you not poke out your eyes like the usual Oracle tools)
has many nice features, like showing tables filtered
lets you connect to multiple oracle instances at once
you can use sane configuration like ip:port username/password and do not have to use those strange TNSNAMES.ORA file based settings
you can set breakpoints and step through the code of stored procedures.
PL/SQL Developer from Allaround Automations.
I happily paid the $200 or so price for this.
Excellent IDE (+ good Intellisense, + debugging capability) with easy creation and editing of PL/SQL packages, SPs, Triggers etc
So much better than Toad.
Toad, from ToadSoft.com -> http://www.toadsoft.com/toad_oracle.htm
For someone like me who likes to work with a DBA tool like Microsoft's SQL Management Studio, it's a life saver.
As a professional PL/SQL developer I use (heh) PL/SQL Developer from Allaround Automations.
I've worked with TOAD for quite a long time but now it is quite overpriced comparing with PL/SQL dev. It has some advantages like knowledge base or ability to work with other RDBMS like SQL server but that's not a necessity for me.
But Notepad++ will always help to make occasional fix.
I always use PL/SQL Developer from Allround Automations.
http://www.allroundautomations.com/plsqldev.html
But some at our place swear by Toad
Use Oracle's own SQL Developer. If you are mainly working with Oracle, it does everything you'll need.
I use TOAD with our Oracle reports development, and I think that it's a good development tool. I normally toggle back and forth between a number of different Oracle instances and schemae, and I like the way that TOAD can display multiple windows for each instance/schema, or even more than one per schema.
TOAD takes a little while to learn and customize, but it's a worthwhile investment. The layout is similar to the Visual Studio .NET IDE with sidebars that can be anchored or rolled away. Tabs display different aspects of the Oracle schema, including procedures, jobs, stats, etc. And when I'm writing SQL, the editor uses color-coding and the error messages are Oracle-specific.
Toolset for Oracle (TOra) is a free, Open Source Database Tool very similar in scope (and look and feel) to Quest's TOAD
Compared to the freeware edition of TOAD, TOra allows multiple connections to different database instances at the same time, and has no concurrent connection limit (so any number of TOra users can be working on the same database instance)
I just used a standard editor (vim which then gave me syntax highlighting).

I like SQL Developer from Oracle. Oh and its free! :)
I like Rapid SQL, you can debug SQL too
Notepad++ stays my favourite editor. I had to use SQL Developer in the past, it's not so "bad", but I encountered many problems with it. It proved very unstable so I wouldn't recommend it, or maybe only to test your procedures.
I use JetBrains IDEA (a Java IDE) to edit and SQL*Plus to execute. The advantages of using a tool with local version control, seemless integration into Source Version Control, advanced find and highlighting, great editing, 'live templates' and so on for me outweighs any advantage of having it 'database aware' (which with plug-ins you can get anyway). If I was coding up a complicated query I might fire up SQL Developer, but generally I prefer great text editing features.
I use Oracle SQL Developer - the latest version also has support for CVS and Subversion.
It has the bonus of supporting other database providers, too.
I have used this tool for 2 years and it has now settled down to be reliable.
I've used RapidSQL by Embarcadero on several different DB platforms, and it's awesome. It has an integrated step debugger, too. I haven't actually used it with Oracle, but I know it's supported.
Another vote for Oracle SQL Developer. It's free, it's stable and it does all the basics that I require.
With the mentioned SQL Developer you can even set breakpoints and step through the code of the stored procedure.
Yet another vote for Oracle SQl Developer. But TOAD works too.
A really good text editor with syntax highlighting (e.g. Textpad from www.textpad.com) and SQL Plus.
For me its, Oracle SQL Developer. The learning curve is very minimal if you have worked on IDEs like Eclipse or VS. You can set break points, read live values when you debug stored procs as you would do to code in eclipse/VS.
Ofcourse the UI is a bit sluggish at times but given that its free compensates the sluggishness.
I use Textpad, Clipmate and Quest SQLNavigator. The newer versions of Quest's SQLNavigator and TOAD are crap -- they tend to crash easily and don't play nice with XP/Vista/Win7.
I've spent hours with their tech support and they don't have alternatives.
You get no access to Quest programmers, but rather you get bogged down in their
trouble ticket process.
Quest needs to focus less on integration of different tools into one and selling you
promises that the next version will solve the instability issues.
They need stability.
This means cleaning up their existing codebase or starting over.
More competent programmers, fewer salespeople, fewer tech support people.
Fix the damn problems.
They focus on sales and it's an idiotic business strategy.
This seems to be a problem across the industry.
Quest's TOAD and SQL Navigator have become bloatware and will soon become abandonware
if they don't turn them around and make them more stable.
I copy and paste frequently between Textpad and Quest SQLNavigator because SQLNavigator
crashes and I lose all my sql code up to the point of crash.
I'll probably dump SQLNavigator once I find something more stable.
SQL Developer from Oracle
We have replaced all other tools at our (large well known) enterprise that has over 150 databases and it works just fine. It's not as good as TOAD but it is getting there, and (unlike TOAD) it's free.
SQL Developer also works well enough connecting to SQL Server
