I will keep it short. Last project proposal I wrote was for a client who just wanted any alternative to QlikView. Few reasons they gave were VERY high hardware requirement, technical resources(people who know QlikView) are VERY rare and licencing costs are high(or not good .. I don't understand this part, don't ask).

So technically I find QlikView very good but be sure you check on other factos like maintenance cost and licencing.

Happy hunting 😉
