The present invention relates to a method and system for retrieving data and displaying content density of a data storage. The data retrieval system of the present invention is essentially comprised of a querying interface, a data storage, a data retrieval component, a retrieved data processing component, and a displaying unit. The data retrieval system further comprises of a data querying and organizing component. The data querying and organizing component is essentially comprised of a first querying member, a second querying member, and an assigning member. The first querying member is essentially adapted to execute a first query to retrieve data from the data storage based on at least a portion of content items in query and the second querying member is adapted to execute a second query to retrieve distinct data from the data storage based on at least a portion of distinct content items in query. The assigning member is adapted to compare records from result of the first query and records from result of the second query, to acquire number of occurrences of each of the records of the second query result into all of the records of the first query result; to assign a frequency weight to each of the records of the second query result according to the acquired frequency of occurrence, and to assign a predefined formatting style to each of the records of the second query result according to the frequency weight of the corresponding record of the second query result. The records of the second query result are displayed in a representation through the displaying unit according to the assigned formatting style. As a result, the content density of the corresponding record of the second query result in the data storage can be portrayed. The method of the present invention generally comprises the steps of querying the data storage, retrieving data from the data storage, processing the retrieved data, and displaying the retrieved data. |
