An aspect of all databases is the ability to search for the "correct" data. Specifically, I am thinking of search engines, such as Google, but they still store and manipulate data. My thought? The ability of the database to understand what you are searching for (artificial intelligence (AI)).
My issue revolves around issues such as searching for product reviews or articles. Recently, I searched for a particular battery (specification) used in watches. Many, as in majority, of the hits related to selling the battery, not providing you with the battery specifications. In fact, some of the sites claiming to have the battery, did not even have it. So it would be nice to filter out all this commercial junk through an effective AI.
Now, I realize that companies purposely "game" the search engines so that you will unsuspectingly stumble into their website and that we really can't stop that type of abuse. For example many companies have "product reviews" that are nothing more that a sales pitch, so the AI would need to differentiate a real review from a fake review.
Irrespective of whether its a webpage or a simple database, it would be beneficial to have an AI that can "know" what you want. I think this concept would become increasingly important as we move deeper and deeper into the information age and virtually everything we do is recorded.
