Engine to handle queries to SAL containment

The Nepomuk query service is not running. Unable to answer queries without it.

Now, each one of those queries has an interesting life and tale of its own.

Right now, if we look at web queries, more than 80 percent of them get handled successfully the first time.

But basically, what we've noticed is these queries, which come in at thousands per second, are available everywhere there is power.

Now this was used over a million times on the first day, and this is really the best of all the queries.

So, the most common use is to embed SQL in programs but for the demos in our videos, naturally, we'll be submitting queries through a GUI interface.

The last thing I wanted to mention about SQL is that it is a declarative language. That means that in SQL, you'll write pretty simple queries that say exactly what you want out of the database, and the queries do not need to describe how to get the data out of the database. The language is also based on relational algebra, and I hope you've watched the relational algebra videos.

The context here is that we developed a system that uses short code SMSs and we get people sending in queries about the amounts of money that have been allocated for projects at a local level.

When SQL is used, it can be used in a database system interactively through a graphical user interface or a prompt so you type SQL queries or commands and you get results back, or SQL can be embedded in programs.
