PivotEngine 성능

PivotEngine은 클라이언트 또는 서버에서의 큰 데이터 집합을 요약할 수 있습니다. 어느 쪽이든 데이터 요약은 비동기적으로 생성되므로 데이터를 요약하는 동안 UI가 계속 응답합니다.

이 예제에서는 크기가 서로 다른 클라이언트 측 데이터 셋트를 요약하는 데 걸리는 시간을 보여줌으로써 성능을 보여 줍니다.

데이터 셋트가 실제로 큰 경우(수백만 개의 레코드), SSAA 큐브 또는 ComponentOne Data Services와 같은 서버측 OLAP 공급자를 사용하는 것이 좋습니다. PivotEngine은 다음 중 하나에 연결할 수 있습니다.
