• 能够通过真实表以及集合立方体单元格值的信息，创建附加的计算度量。

• 支持维数或者层次的合适成员。

• 支持存储了维数或者层次成员附加信息的维数或者层次属性。

• 当一个立方体单元格中存储了真实表中的两个或者多个值时，支持过度饱和立方体。

关键特征：数据视觉化

• 支持 Unicode.

• 在 Grid 同步时，能够显示多个度量。

• 对每个单元格，交互式 drill-down 分别支持所有层次类型。

• 在 OLAP 分析时，支持 "Undo" 以及 "Redo".

• 支持保存以及修复当前 OLAP 片断。

• 在不改变层次级别结构的基础上，支持任何层次级别上的成员分组。

• 支持任何层次或者维数级别上的单独排序。能够重载任何排序函数。

• 能够依据 OLAP 网格中的列值进行升序或者降序排序。

• 在 OLAP 计算中，应用或者不应用过滤器，都支持过滤任何层次成员组。

• 根据网格中的值，自动过滤层次成员。能够根据成员的级别或者仅根据理论，来选择一些主要/次要成员。

• 在网格中，不仅能够显示度量值，而且还能显示总计百分比、小计百分比或者主要部分总计的百分比。能够创建自己的用于显示度量的上下文相关规则（例如：测量值对时间维的累积和）。

• 依据程序员指定的参数，能够在任何网格中自动制图，以及对网格中的图片定位。

• 完全的数据输出控制，能够在网格中任意绘图。

• 在网格中，支持自定义绘图。

• 在网格中，支持自定义弹出菜单。

• 在网格中，支持拖放度量或者层次成员。

• 依据单元格的宽度，自动封装其内容。对于网格中过长的单元格，能够自动调整具有自动封装的列宽。

• 能够直接在网格中编辑 OLAP 数据（支持 "writeback"）。

• 允许把当前片断显示为图表（任何 TChart 后继）。在图表中，支持 Drill-down 操作。可免费获得制图组件的源码。

• 允许把选定的网格区域拷贝到剪贴板中。支持所有公共的 office 剪贴板格式。

• 允许把网格数据导出到多种格式：MS Excel (使用 OLE 或者直接导出到 XLS-file), HTML, PDF, WMF, RTF, TXT, BMP, XML. 很快也可以导出到 RaveReport, ReportBuilder, FastReport. 它还支持在 printer Canvas 中直接绘图。

• 易于本地化。还能够局部化试用版。

Key features: Cube definition

• Support of the following data sources:
  • A single table or query of any database (any TDataSet successor, no BDE required);
  • Several tables or queries of any database organized into the "star" or "snowflake" schema (any TDataSet successors, no BDE required);
• Support a set of aggregation functions, such as Sum, Count, Distinct Count, Min, Max, biased or unbiased variance, median and so on. Supports custom aggregation functions.
• Support of numbers, strings and dates as measure values.
• Support of measure grouping.
• Support of all cube structure elements of Enterprise OLAP servers (dimensions, hierarchies, hierarchy levels and their relations). You can build the cube in the Desktop OLAP, and then, when increasing the size of tables, to port the Desktop cube into the MS Analysis cube, at that the logical structure of the cube will remain unchanged.
• Support of hierarchies of three types:
  • Parent-child hierarchies;
  • Multilevel hierarchies;
  • Mixed from both previous types.
• An ability to create calculated measures, dimensions, hierarchies and hierarchy levels based on the data both as the fact table rows and all dimension tables rows related to it with the foreign keys.
• An ability to create additional calculated measures, using both the information from the fact table and values of the aggregated cube cells.
• Support of calculated members of dimensions or hierarchies.
• Support of dimension or hierarchy attributes which store additional information about dimension or hierarchy members.
• Support of supersaturated cubes when one cube cell holds two or more values from the fact table.

Key features: Data visualization

• Unicode support.
• An ability to display many measures in the Grid simultaneously.
• Interactive drill-down support of all types of hierarchies separately for every grid cell.
• Support of "Undo" and "Redo" actions during the OLAP analysis.
• Support of saving and restoring the current OLAP slice.
• Support of member grouping on any hierarchy level without changing the hierarchy levels structure.
• Support of sorting on any level of hierarchy or dimension separately. Ability of overriding any sorting method.
• Support of ascending or descending sorting based on any column value in the OLAP grid.
• Support of filtering any set of hierarchy members with or without applying these filters in the OLAP calculations.
• Support of the auto filtering of the hierarchy members depending on their values in the grid. An ability for selection some major/minor members, either according to their rank or on the Pareto principle.
• An ability to display in the grid not only the values of the measures but a percent value regarding totals, subtotals, or grand totals. An ability to create your own context-sensitive rules on measure display (for example, a cumulative sum of measure values for time dimensions, and just its value for all other cases).
• The auto image drawing in any grid cell, the auto picture positioning in a cell, depending on the parameters assigned by a programmer.
• A complete data output control, a feature for the arbitrary drawing in the grid cells.
• Support of the custom drawing on the grid cells.
• Support of the custom popup menus in the grid.
• Support of the drag-n-drop of measures or hierarchy members within the grid.
• Auto wrapping of the cell contents depending on its width. Auto sizing of the column width with auto wrapping for the very "long" cells of the grid.
• An ability to edit OLAP data directly in the grid ("writeback" support).
• Allows to display the current slice as a diagram (any TChart successor). Support of Drill-down actions in the chart. The source code of the charting component comes for free.
• Allows to copy the selected grid area into the clipboard. Support all common office clipboard formats.
• Allows to export grid data to many formats: MS Excel (using OLE or directly to XLS-file), HTML, PDF, WMF, RTF, TXT, BMP, XML. Exports to the RaveReport, ReportBuilder, FastReport are coming soon. Also supports direct drawing on printer Canvas.
• Easy localization. It is possible to localize the evaluation version as well.
