 each one of the plurality of magnetic heads. Each second electrical connection is exposed on an outside surface of a magnetic head. ESD protection is advantageously provided by the first and the second electrical connections until the wafer is cut and lapped along the contemplated ABS line to form the ABS, which severs each first electrical connection. Thereafter, the wafer is cut to separate the plurality of magnetic heads from each other where each head is then processed individually. During the separation and individual processing, ESD damage is advantageously prevented by each second electrical connection. Each exposed second electrical connection is eventually severed, preferably by laser-deletion, so that each magnetic head can be used as intended. The present invention relates generally to processing data in a data warehouse, and more specifically, to a method and system that allows a user to perform operations on subsets of data that are not defined by the structure of the data warehouse.
Contemporary database environments store and manage data, such as the sale and inventory of products sold by a retailer. Such a database environment may include a data storage system responsible for storing the data, with data encryption, data redundancy, backup facilities, data compression, or the like, as specified by an administrator. Similarly, the database environment may include a user interface that allows one or more users to access and process the data in the data storage system in a meaningful way (e.g., for preparing sales reports, inventory reports, etc.).
The representation of data displayed to a user may differ significantly from the logical or physical representation of the same data elsewhere within the database environment. The database environment thus serves, on the one hand, to store the data in an efficient and secure manner and, on the other hand, to process and present the data to a user in a meaningful way without overly encumbering the user.
Database environments typically include one or more data tables, i.e., logical arrays of data, with each data table containing a plurality of identically structured records. For example, in a data table relating to sales transaction data, the data table may include a plurality of rows, with each row containing the data associated with an individual record, for example, an individual sales transaction. In such cases, a row of data is synonymous with a record of data. Each column of the data table typically contains data relating to an aspect of a record. In the given example, each column contains data relating to an aspect of the respective sales transaction, for example, the date of the transaction, the time of the transaction, the location, the

ESD protection is advantageously leave by the first and the second electrical joining until the wafer is cut and lapped along the contemplated abdominal line to form the ab, which severs each first electrical connection. Thereafter, the wafer is cut to separate the battalion of magnetic heads from each other where each fountainhead is then processed individually. During the separation and individual processing, ESD price is advantageously prevent by each second electrical connection. Each exposed second electrical connection is finally severed, preferably by laser - deletion, so that each magnetic head can be used as intended. The present invention relates by and large to processing data in a data warehouse, and more specifically, to a method and system that allows a user to perform operations on subsets of datum that are not specify by the structure of the datum warehouse. 
 contemporaneous database environments store and manage data, such as the sale and inventory of products sell by a retailer. Such a database environment may include a data storage system creditworthy for storing the data, with data encryption, data redundancy, backup facilities, data compression, or the like, as specified by an administrator. Similarly, the database environment may include a user interface that allow one or more user to access and process the data in the data storage system in a meaningful direction (e.g., for preparing sales report, inventory reports, etc .). 
 The representation of data display to a user may disagree significantly from the logical or physical representation of the same datum elsewhere within the database environment. The database environment thus serves, on the one hand, to store the data in an effective and secure manner and, on the other hand, to serve and present the datum to a user in a meaningful way without overly restrain the user. 
 Database environments typically include one or more data table, i.e., logical arrays of data, with each datum table containing a plurality of identically structured records. For example, in a data board relating to sales transaction data, the data table may include a battalion of rows, with each row contain the data associated with an individual record, for example, an individual sales transaction. In such cases, a quarrel of data is synonymous with a record of data. Each column of the datum table typically check data relating to an expression of a record. In the given example, each column contain data relating to an view of the respective sales transaction, for example, the date of the transaction, the time of the transaction, the location, the
