With a Simulator for Database Aggregation using metadata, the end-user application now speaks \"base-level\" SQL and never attempts to call for an aggregate directly. Using metadata describing the data warehouse's portfolio of aggregates, the aggregate navigator transforms the base-level SQL into \"simulator-aware\" SQL. The end user and the application designer can now proceed to build and use applications, blissfully unaware of which aggregates are available.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783848438709\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783848438709","offer_id":39437002080349,"sku":"9783848438709","price":49.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/18ecf781-ccf6-4785-981c-b22b20e814f5.jpg?v=1773124311","url":"https:\/\/shop.autorenwelt.de\/en\/products\/simulator-for-database-aggregation-using-metadata-von-sandeep-kumar","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
