Abstract
In the data control apparatus for managing data including the time information such as date, when the research period is set as the data retrieval condition, the data including the time information of the retrieval period is selected. The dates of the start point and end point of the research period in the data retrieval in the year unit are always the same, and the days of the start point and end point of the research period in the month unit are determined depending on each month. That is, in the data control apparatus of the invention, when only the year is entered when setting the research period, 'January 1' and 'December 31' are automatically set as the dates of the start point and end point. Or when the month and year are entered, the 'first' and the 'end day of that month' are automatically set as the days of the start point and end point. Therefore, the load of the operator for setting the research period may be alleviated.
