It also measures the dower completion during an Extract -Transfer- Load (E TL) and/or refresh process. This metric also, and helps identify any possible SQL problems in spite of appearance a crabby table. 2. Connectivity Response Time = #Users x (RTD% + TR%) Where lead Time Duration (RTD) in minutes = Hardware/DW surface Transfer reckon (TR) = Actual Transfer target/ best Transfer Rate This metric measures connectivity by enabling the devoted to identify and isolate underlying issues including ISP transfer estimates, data sources, and computer hardware issues. 3.

data Integrity Data Quality Tool Rate/Manual = % Accuracy This metric measures the avoidance of the tedious, resource inte nsive method done in the past. 4. Usage Dat! a from the Data Warehouse Usage Rate on Data = roughly frequently used/Total This metric tracks the usage run of tables, reports, and the overall data warehouse to identify any trends and/or problems that may occur, particularly during peak operating snips. 5. On-Time delivery This up-to-the-minute metric is defined as: tables are on time if they are delivered by 7:00AM... If you want to get a safe essay, order it on our website: OrderCustomPaper.com
