1. A computer-implemented method for performing customized large-scale data analytics, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: providing a logical-data-model user interface to enable modifying a logical data model of a relational multi-dimensional analytic database by providing a representation of data currently stored within the relational multi-dimensional analytic database via the logical-data-model user interface; receiving, via the logical-data-model user interface, user input to modify the logical data model of the relational multi-dimensional analytic database, the user input identifying the data currently stored within the relational multi-dimensional analytic database; modifying the logical data model of the relational multi-dimensional analytic database based on the user input by adding a dimension to the logical data model that represents the data currently stored within the relational multi-dimensional analytic database; providing a visualization user interface, after modifying the logical data model, to enable performing online analytical processing operations on a multi-dimensional dataset defined by the logical data model, wherein the multi-dimensional dataset defined by the logical data model excludes at least one irrelevant dimension representing data stored within the relational multi-dimensional analytic database, thereby initiating browsing of the relational multi-dimensional analytic database with a starting view limited to the multi-dimensional dataset defined by the logical data model; receiving, via the same visualization user interface, a request to perform an online analytical processing operation that provides a subsequent view of data stored within the relational multi-dimensional analytic database in accordance with the logical data model, thereby facilitating browsing the relational multi-dimensional analytic database from the starting view to the subsequent view without browsing through any view that comprises the irrelevant dimension.
