Hi,
-
An entity is a physical or abstract object (for example, Mr. Douglas, the "Sales Information System" project) that can be distinguished from other objects and for which information is to be stored. Entities are divided into entity types according to their properties.
Each entity type is assigned attributes, which describe the entities of the entity type. The properties of entities are described by means of actual values for the attributes.
An attribute consists of a name and a definition of the possible values for the attribute (for example, the attribute color with the values white, black, yellow, and so on). One or more attributes are labeled as key attributes. The values of the key attributes uniquely identify an entity within its entity type.
-
Attributes define the possible properties for entities of an entity type.
Attribute type
The attribute type describes the function of an attribute (for example, whether an attribute is a key attribute).
Defining attributes
Attributes are either assigned directly to an entity type or transferred from the ABAP/4 Dictionary.
Attributes that are assigned directly obtain their semantic and technical characteristics from a data element which is assigned to the attribute. Since the Data Modeler and the ABAP/4 Dictionary use the same data elements, data elements defined in the Data Modeler can be used later in the ABAP/4 Dictionary and vice versa.
Attributes are transferred from the ABAP/4 Dictionary by assigning a table or view to an entity type. The fields of the table or view are transferred to the entity type as attributes and receive their semantic and technical characteristics from the data elements of the fields. Attributes transferred from the table or view are flagged in the Data Modeler. Assigning a view or table to an entity type establishes the connection between the Data Modeler and the ABAP/4 Dictionary.
I hope this will give u an idea on the path.
Regards.
