The most important part of a dimensional design is the framework of conformed dimensions. As you have learned, conformed dimensions are the key to linking data from more than one fact table, whether within a single subject area or across subject areas. The process of linking this information together within a report is referred to as drilling across, as discussed in 5. Use of a table diagram to depict conformed dimensions is usually impractical. When more than three fact tables are displayed, it becomes difficult or impossible to lay out a diagram in a readable format. A better way to depict conformed dimensions is to make use of matrix diagrams. Each row of the matrix corresponds to a fact table; each column corresponds to a dimension table. Conformed dimensions are grouped in shaded bands for readability. Degenerate dimensions are included as well. For each fact table, checkmarks are placed beneath all dimensions for which information is available. An example is depicted in Figure 18-8.

Tools and Documentation
Notice that this diagram is made easier to use by placing checks beneath all applicable headers. For example, order_facts includes full details on salesrep. Rather than simply placing a checkmark under salesrep, the diagram also places checks under conformed rollups region and territory. This practice allows instant identification of compatible fact tables. If two fact tables have checkmarks in the same column, that dimension can be used to compare them. The region dimension, for example, is a conformed rollup of salesrep. It can be used to compare demand_forecast_facts with order_facts. The conformance matrix in Figure 18-8 only contains major dimensions of significance to the enterprise. This kind of conformance matrix may also be supplemented with a second conformance matrix, which includes all dimension tables that are part of the solution. Such a matrix will be significantly wider.
Detailed Design Documentation
Top-level documentation of stars and dimension tables must be backed up with detailed column-level and table-level specifications. The detailed specifications define each column, its data type, its data source and transformation rules, and other salient characteristics. This information is normally presented in a tabular format. It can be produced using a spreadsheet tool. Some data modeling tools may also be able to produce this information. Detailed design specifications should be divided into two major sections: one for dimension tables and one for fact tables.
Dimension Detail
The detailed design specifications for each dimension table are made up of two parts. The first part is a spreadsheet-style table with one row for each attribute in the table. Columns provide the documentation elements described in Table 18-4. The second part depicts table-level characteristics described in Table 18-5. For dimensions that include multiple sources, it will be necessary to expand on this format. In the case of discrete sources that each provide separate subsets of the dimension, the source element and transformation rules can be repeated, once for each data source. In situations where the data sources must be cross-referenced and mediated for each row in the dimension table, this processing may be described using pseudo-code as part of tablelevel information. Table-level specifications provide information pertaining to the table itself. This includes information about the relationships between the various source systems, any pseudo-code necessary to indicate how to filter the source data, and other processing logic that cannot be expressed at the column level as described previously. Normally, this table-level detail is provided after the column-level detail. For particularly complex load processes, it may be necessary to reverse the order, in which case table-level information and high-level pseudo-code describe the overall processing approach and are followed by the column-level documentation. A complex load process may be aided by the creation and management of one or more staging tables. These tables do not fall within the domain of the dimensional model and will not be accessed by users or reports. They may be designed and documented by the ETL developers. Such intermediate tables need not be included in the dimensional design documentation, unless they are necessary to provide a logical overview of processing rules.
