Abstract

The Entity Relationship Diagram (ERD) is one of the most important data modeling techniques in the database design process. ERDs are used to represent data in a conceptual form before being implemented into the actual database schema. By using an ERD, developers can illustrate the relationships between entities, the attributes possessed by each entity, and the types of relationships that occur between these entities.The use of ERDs in database design has several main benefits. First, ERDs help to accurately and consistently model data requirements before the implementation stage. Second, ERDs provide a clear visual representation of the data structure, facilitating communication and understanding among team members. Third, ERDs serve as the basis for designing an efficient and well-structured database schema.Despite being an essential technique, many developers still struggle with creating accurate and appropriate ERDs. Errors in designing ERDs can cause serious problems in database implementation, such as data redundancy, anomalies, or even data loss. Therefore, a deep understanding of the concepts and rules in creating ERDs is crucial.In this journal, an example of a correct ERD will be presented along with a detailed explanation of each entity, attribute, and relationship involved. This discussion is expected to provide guidance for readers in designing accurate ERDs that meet the requirements, thereby producing an efficient database.

Abstract

The development of information technology has been widely implemented in various types of businesses, both businesses in the sale of products and businesses in the service sector, in order to facilitate the work process. The design of the barbershop service application aims to help manage the service process in the barbershop location area. Based on researchers' observational data, the condition of the barbershop which has many customers every day has service constraints in the queue of orders and payment transactions at the barbershop. This results in loss of customer time as well as from employees and barbershop owners. From this problem, we need a service application that is expected to minimize the density of customer queues in ordering services and payments. The analysis and design of this application aims to help the owner of the barbershop in serving customers, using structured system development (SDLC) modeling that has limits or scope of research that starts from the planning to the design stage, namely the application interface design. So this research can produce customer service application designs that can help solve customer queue service problems.
