The Data Types in FEKL are based on the Data Types available for Value Types in the Boston conceptual modelling software.
NB Value Types in Object-Role Modeling software require Data Types such that the corresponding Column/Attribute/Property/Field within the respective Entity-Relationship Diagram and Property Graph Schema have a Data Type that is commensurate with the Data Type of the corresponding Column/Attribute/Property/Field within any underlying/connected database.
NB Some Data Types require either a Length or a Precision to be specified.
E.g. Data Type with Length
E.g. Data Type with Precision
The following are a list of Data Types in Boston.
