{"product_id":"9781786305855","title":"Data Lakes","description":"The concept of a data lake is less than 10 years old, but they are already hugely implemented within large companies. Their goal is to efficiently deal with ever-growing volumes of heterogeneous data, while also facing various sophisticated user needs. However, defining and building a data lake is still a challenge, as no consensus has been reached so far.  Data Lakes presents recent outcomes and trends in the field of data repositories. The main topics discussed are the data-driven architecture of a data lake; the management of metadata – supplying key information about the stored data, master data and reference data; the roles of linked data and fog computing in a data lake ecosystem; and how gravity principles apply in the context of data lakes.   A variety of case studies are also presented, thus providing the reader with practical examples of data lake management.","brand":"Anne Laurent","offers":[{"title":"Default Title","offer_id":47052043059518,"sku":"9781786305855","price":0.0,"currency_code":"ZAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4357\/7662\/products\/9781786305855_72e907dc-8cdc-4a8c-bef7-dd51d7dfe5d3.jpg?v=1707623939","url":"https:\/\/exclusivebooks.co.za\/products\/9781786305855","provider":"Exclusive Books Online","version":"1.0","type":"link"}
