System und Verfahren zum selektiven Indizieren von Datenbanken |
摘要 |
<p>A method for selectively indexing a database (32) includes selecting a set of fields (156) in the database (32). The selected fields (156) are located in one column (152) of a table (150) in the database (32). The method also includes determining the total time required for reading data from the fields (156) during a selected time period if the fields (156) are indexed and determining the total time required for reading data from the fields (156) during the selected time period if the fields (156) are not indexed. The method further includes determining the total time required for writing data to the fields (156) during the selected time period if the fields (156) are indexed and determining the total time required for writing data to the fields (156) during the selected time period if the fields (156) are not indexed. In addition, the method includes evaluating the total times required for reading and writing data to the fields to determine whether the fields (156) should be indexed.</p> |
