Valentina DB is faster 100 times of SqlLite, mySQL

And can be perfectly embedded into commercial application because it is
royalty free.

You need Valentina DB.

Okay you need 5K for each record.
How many fields?

Let me remind that Valentina has columnar format.
This is huge advantage.

Also Valentina can give you not only SQL way but NON-SQL way,
Which can be additionally 10-20 times faster!

I can tell you store, that Valentina was tested for AOL Europe by their dev
team. Against Berkly,  mySQL, postgre, and other dbs. SqlLite even was not
in game of course.

Task was so simple. Table has 2 fields {URL, PictureBannerAd }

So when somebody ask for a WEB page, it needs find banner to be shown.

As they told, e.g. Berkly have give 100 faults per time (min our hour I not
remember now).  Other dbs also. Fault means that banner was not found  by DB
in time less of timeout.

Valentina have give them zero faults.

Let me underline this very important feature NON-SQL-ness of Valentina.
As well as very powerful SQL.

Today is very modern stream talk about how SQL DBs are bad, and how cool are
NON-SQL with Key-Value.  Guys, be happy, Valentina is perfect for both
tasks. :-)

If talk about details, in V4REV API (and most others Valentina ADKs) you can
use not SQL way to do searches and sortngs using

And other similar search methods.  They are really FASTEST POSIBLE way.
