    <p>I want to measure the performance and scalability of my DB application. I am looking for a tool that would allow me to run many SQL statements against my DB, taking the DB and script (SQL) file as arguments (+necessary details, e.g. host name, port, login...).</p> <p>Ideally it should let me control parameters such as number of simulated clients, duration of test, randomize variables or select from a list (e.g. SELECT FROM ... WHERE value = @var, where var is read from command line or randomized per execution). I would like to test results to be saved as CSV or XML file that I can analyze and plot them. And of course in terms of pricing I prefer "free" or "demo" :-)</p> <p>Surprisingly (for me at least) while there are dozens of such tools for web application load testing, I couldn't find any for DB testing!? The ones I did see, such as pgbench, use a built-in DB based on some TPC scenario, so they help test the DBMS configuration and H/W but I cannot test MY DB! Any suggestions?</p> <p>Specifically I use Postgres 8.3 on Linux, though I could use any DB-generic tool that meets these requirements. The H/W has 32GB of RAM while the size of the main tables and indexes is ~120GB. Hence there can be a 1:10 response time ratio between cold vs warm cache runs (I/O vs RAM). Realistically I expect requests to be spread evenly, so it's important for me to test queries against different pieces of the DB.</p> <p>Feel free to also contact me via email. Thanks!</p> <p>-- Shaul Dar (info@shauldar.com) </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
