QlikView，In-Memory BI

What Makes QlikTech So Good?

So let me try to articulate exactly what makes QlikView so good. The underlying technology is what QlikTech calls an “associative” database, meaning data values are directly linked with related values, rather than using the traditional table-and-row organization of a relational database. (Yes, that’s pretty vague—as I say, the company doesn’t explain it in detail. Perhaps their U.S. Patent [number 6,236,986 B1, issued in 2001] would help but I haven’t looked. I don’t think QlikTech uses “associative” in the same way as Simon Williams of LazySoft, which is where Google and Wikipedia point go when you query the term.)

DBMS：

• Associative Model Of Data
• Relational Model Of Data
• Column Oriented Model Of data

DBMS也该有发展了。
