Data Type Classes
Define properties to contain literal values.
Data type classes enable you to enforce sets of rules about the values of literal-valued properties. InterSystems provides an extensible set of data type classes. Each data type class has the following features:
It specifies values for compiler keywords. Among other things, these control how the property is projected to SQL and to clients such as Java.
It specifies values for property parameters.
It provides a set of methods to translate data among the stored (on disk), logical (in memory), and display formats.
