Process data modeling

Business processes work on data. Clearly showing the data, data types and data dependencies between the activities of a business process , a process management system business to control data transfer related to the production and processing during the process of implementation.

Data modeling,
data modeling in database design is the core. The method of linking entities is used to classify and organize data in a given application domain. The relationship modeling method of the entities belonging to the meta-model level provides the expression of the required concepts for the data model, as shown in the figure below.

Data modeling will be described by a sample application domain , for example by order management . In modeling efforts, the most important entities are identified and classified. Entities are identifiable things or concepts in the real world that are important for modeling purposes. In the sample scenario, orders, customers, and products are among the real-world entities that need to be represented in the data model.
Entities are classified as entity types if they have the same or similar properties. Therefore, orders are categorized by type of entity called orders. Because for each order, order number, date, quantity, and quantity, all order entities can be expressed by this type of entity. The properties of entities are indicated by the properties of the types of related entities.
Institutions classified into one type of entity need a similar structure, but they are not the same structure, because attributes can be optional . If the software domain allows, for example, for an order in order to have or not have a special discount, the value option is optional. This means that two orders are classified into entity type.
The types of entities in the institution connection meta model must be represented in a symbol by a specific symbol. While there are other types of entity connection symbols, entity types are often represented by rectangles, called entity types. The following figure shows the order of entity types in the center of the chart.
Other types of entities in the field of software are examples of customers and products. Properties are expressed as ellipses connected to different types of entities.

Existences are related to each other on the basis of relationships. In the relationship diagram of entities, the type of relationship is usually connected by the rhombus symbol, which is connected to the corresponding entity type by the edges.
