[单选题]You are a database administrator in the Los Angeles branch office of a specialty foods supplier. A mainframe. database at the headquarters contains all company data. Each branch office contains a SQL Server 2000 computer that imports regional data from the mainframe. database.The server in Los Angeles contains a Data Transformation Services (DTS) package that uses OLE DB to connect to the company's mainframe. database. The DTS package extracts and transforms data about buyers and products for that region. The DTS package then writes the data to the SQL Server database in Los Angeles.

正确答案 ：F

On the server in Sydney, install an OLE DB provider for the mainframe. database.

解析：解析：Explanation: OLE DB is an API that allows COM applications to use data from OLE DB data sources, which includes data stored in different formats. An application uses an OLE DB provider to access an OLE DB data source. An OLE DB provider is a COM component that accepts calls to the OLE DB API and performs the necessary processing required by request against the data source. In this scenario the OLE DB source is the company's mainframe. database, which contains all company data. As each branch office contains a SQL Server 2000 computer that imports regional data from the mainframe. database, all existing and future branch office SQL Server 2000 servers will require an OLE DB provider to access the company's mainframe. database.
