<p>The methods and system are provided for organizing a dataset in a database by marking the dataset by a plurality of labels generated based on a pre-defined policy (see Fig.1). The policy determines the data scope accessible to each label (12). A user of the database can access the data within the scopes of one or more labels based on its role and privileges granted thereto by, for example, a system administrator (14). Moreover, a variety of shaping transformations can be applied to the tagged dataset to create a derived dataset that is suitable for the informational needs of the user (16). The derived dataset can be formatted to render it compatible for viewing via a selected presentation engine, such as a web browser (18).</p> |
