AQL Technology (vs OLAP)
Academia de studii economice
Ce este AQL ?
AQL - Advanced Query Logic este o tehnologie
revoluţionară, care accesează informaţiile structurate din
surse variate într-un mod dinamic şi interactiv, propagând
selecţiile de analiză prin întreaga bază de date relaţională
înglobată.
AQL Technology (vs OLAP)
Academia de studii economice
Click !
Fiecare click este o interogare. Extrem de rapid, şi foarte flexibil.
Interfaţa utilizator
Selecţia se propagă prin baza de date relaţională.
AQL
AQL Technology (vs OLAP)
Academia de studii economice
Ce oferă AQL ?
Simplificarea procesului de conectare şi administrare a
structurilor de înmagazinare ale soluţiilor de business
intelligence
(NO DATA WAREHOUSE REQUIRED !)
Viteză remarcabilă de implementare
Viteză incredibilă de returnare a rapoartelor (secunde!)
Portabilitate (“Off-LAP”)
Uşurinţă în utilizare (analize la un “Qlik” distanţă)
AQL Technology (vs OLAP)
Academia de studii economice
Cui foloseşte AQL ?
Tuturor celor care vor răspunsuri instantanee la întrebările lor.
Tuturor celor care nu vor să devină experţi IT pentru a afla
informaţii relevante de la un sistem informatic
Tuturor celor pentru care timpul e critic
Tuturor celor care vor să verifice rapid corectitudinea informaţiilor
pe care le deţin
Tuturor celor care vor să ofere plusvaloare informaţională şi
transparenţă clienţilor sau partenerilor săi
AQL Technology (vs OLAP)
Academia de studii economice
Cine ofera?
QlikTech este o coporaţie suedeză care a dezvoltat această
tehnologie.
Produsul care înglobează această tehnologie se numeşte QlikView
In Romania prin parteneri.

Hyper Cube
Construirea cubului. Multe date. Lent. Totul trebuie predefinit.
Fiecare click este o interogare. Rapid, dar inflexibil. Număr limitat de dimensiuni.

Which graphical chart would you choose?
when you have dollar amount and quantity…when you have actual amount and budget amount…when you display top performers…when you display the ratio (%) of dollar amounts by top performers…when you display the trend line over time…
Straight table or Pivot table?
when you have a dimension and multiple expressions…when you have multiple dimensions…
