A data warehouse is a repository（or archive）of information gathered from multiple sources, stored under a unified schema, at a（ 73 ）site. Once gathered, the data are stored for a long time, permitting access to historical data. Thus, data warehouses provide the user with a single consolidated（ 74 ）to data, making decision-support queries easier to write. Moreover, by accessing information for decision support from a data warehouse, the decision maker ensures that online transaction- processing systems are not（ 75 ）by the decision-supportworkdoad.
