通过对数据进行分组来减少行数

Question

我有一组电子表格，它们定义了一组业务规则。这些业务规则然后由我们的系统处理。

创建电子表格的用户做得太天真了，我发现通过将行间数据分解 - 从而减少规则数量 - 极大地提高了系统的性能。

其中的“天真”结构化的电子表格可能是这样的：

+-----------+------------+------------+------------+------------+--------+ 
| Rule Name | Criteron 1 | Criteron 2 | Criteron 3 | Criteron 4 | Accept | 
+-----------+------------+------------+------------+------------+--------+ 
| Rule 1 |  A  |  B  |  C  |   | Yes | 
| Rule 2 |  A  |  C  |  C  |   | Yes | 
| Rule 3 |  A  |  D  |  C  |   | Yes | 
| Rule 4 |  A  |  E  |  C  |   | Yes | 
| Rule 5 |  A  |  F  |  C  |   | Yes | 
| Rule 6 |  A  |  B  |  D  |   | Yes | 
| Rule 7 |  A  |  C  |  D  |   | Yes | 
| Rule 8 |  A  |  D  |  D  |   | Yes | 
| Rule 9 |  A  |  E  |  D  |   | Yes | 
| Rule 10 |  A  |  F  |  D  |   | Yes | 
| Rule 11 |  A  |  B  |  E  |   | Yes | 
| Rule 12 |  A  |  C  |  E  |   | Yes | 
| Rule 13 |  A  |  D  |  E  |   | Yes | 
| Rule 14 |  A  |  E  |  E  |   | Yes | 
| Rule 15 |  A  |  F  |  E  |   | Yes | 
| Rule 16 |   |   |   |  G  | Yes | 
| Rule 17 |   |   |   |  H  | Yes | 
| Rule 18 |   |   |   |  I  | Yes | 
| Rule 19 |   |   |   |  J  | Yes | 
| Rule 20 |   |   |   |  K  | Yes | 
| Rule 21 |   |   |   |  L  | Yes | 
| Rule 22 |   |   |   |  M  | Yes | 
| Rule 23 |   |   |   |  N  | No | 
| Rule 24 |   |   |   |  O  | No | 
| Rule 25 |   |   |   |  P  | No | 
| Rule 26 |   |   |   |  Q  | No | 
| Rule 27 |   |   |   |  R  | No | 
| Rule 28 |   |   |   |  S  | No | 
| Rule 29 |  A  |  J  |  F  |   | No | 
| Rule 30 |  A  |  K  |  F  |   | No | 
+-----------+------------+------------+------------+------------+--------+ 

作为一个例子，第1条将被评估为：

IF (Criterion 1 == A) AND (Criterion 2 == B) AND (Criterion 3 == C) THEN Accept 

必须思考和假设我们可以在我们的列中使用OR条件，上面的可以简化为：

+-----------+------------+------------+------------+-------------+--------+ 
| Rule Name | Criteron 1 | Criteron 2 | Criteron 3 | Criteron 4 | Accept | 
+-----------+------------+------------+------------+-------------+--------+ 
| Rule 1 |  A  | B,C,D,E,F | C,D,E |    | Yes | 
| Rule 2 |   |   |   |G,H,I,J,K,L,M| Yes | 
| Rule 3 |   |   |   |N,O,P,Q,R,S | No | 
| Rule 4 |  A  |  J,K |  F  |    | No | 
+-----------+------------+------------+------------+-------------+--------+ 

规则1现在是评估如下：

IF (Criterion 1 == A) AND 
    (Criterion 2 == B OR Criterion 2 == C OR...) AND 
    (Criterion 3 == C OR Criterion 3 == D OR...) THEN Accept 

现在，我已经做了这个手动。我想知道的是：Excel是否具有内置功能来为我进行这种分组。如果没有，任何人都可以指向我的算法的方向，这将有助于我有效地实现这一点？

Answer 1

这看起来像一个情况下，你可以查询使用ADO和OLE DB到ADO记录集使用GROUP表由SQL查询HAVING，然后转储（分组）的结果为使用CopyFromRecordset

你的新工作表

另外，也许是一个数据透视表？
