Assignment-3 Logical Data ModelInstructions:Draw a logical data model (ERD) for the Picnics R US case [Refer to ‘Assignment#1’ and‘Assiignment#2’ on Canvas under ‘Assignments’]Guidelines:A data model describes the data that flow through the business processes in anorganization. It represents the logical [rather than physical] organization of data]. Lateron in the system development process, the data model is changed to reflect exactly howthe data will be stored in databases and files.Hints:Whereas a process model (DFD) represents how the business system will operate, adata model (ERD) represents how the data that flow through the processes areorganized and presented. A data model is a formal way of representing the data that areused and created by a business system. Data stores of the DFD generally correspond toentities of the ERD: Identify the entities Add appropriate attributes for each entity Draw the relationships that connect associated entities Check the process models for data stores, external entities, and data flows Check the major inputs and outputs from the use cases Identify attributes of the entity that are relevant to the system under development Check the process model repository entries for details on data flows anddata stores Check the data requirements of the requirements definition Select each entity’s candidate identifier Start with an entity and identify all entities with which it shares relationships Determine the cardinality and modality of the relationships
