Chapter 2: <strong>The</strong> dTIMS CT Database<br />

2.2 Attributes<br />

In the previous section Perspectives were described as objects that are used to contain<br />

groups <strong>of</strong> assets with similar characteristics. <strong>The</strong> next step in a database design is to define<br />

the characteristics you want to describe within each Perspective. <strong>The</strong>se characteristics are<br />

called Attribute objects in dTIMS CT.<br />

Attribute objects allow you to define the asset characteristics you want to store in each<br />

Perspective. In the analogy where Perspectives are thought <strong>of</strong> as tables, Attributes can<br />

represent the columns (fields) in each <strong>of</strong> the tables.<br />

Table 12 to Table 42 in Appendix “A” list the attributes defined in each perspective listed in<br />

Table 1.<br />

Each Attribute table in Appendix “A” lists the Perspective to which the Attributes belong to,<br />

the Attribute Name, a short description <strong>of</strong> the Attribute (as it appears in dTIMS CT) and the<br />

Attribute Type.<br />

Attributes • Attribute Type<br />

Every attribute you create is assigned a specific data type, which determines the kind <strong>of</strong> data values<br />

that can be entered into an attribute’s cell. Attribute Type is important when designing your database<br />

because once you create an attribute in dTIMS CT you cannot change its type. It is important to note<br />

that dTIMS CT displays data values for attribute types in the format that you have specified in your<br />

Windows | Regional Settings. When you create an attribute, you will need to specify one <strong>of</strong> the<br />

following data types:<br />
