ERD (Entity Relationship Diagram) pada Sistem Informasi Layanan Publik di Suatu Kelurahan

Summary

In this tutorial, Putri Aulia Zainul (Ailee) introduces how to create an Entity Relationship Diagram (ERD) for a public service information system in a village. She explains the concepts of entities, relationships, and cardinality, using a real-world example of a village's online service system. The system helps citizens submit documents like KTP or KK applications, with admins processing them and providing updates. Ailee guides viewers through creating the ERD, covering the necessary entities like citizens, submissions, and admin tasks, as well as their attributes and relationships. The video aims to simplify ERD creation for users in database design.

Takeaways

• 😀 The tutorial covers how to create an Entity Relationship Diagram (ERD) for a public service information system in a village.
• 😀 ERD is a data representation model using entities and relationships to describe the logical structure of a database in a graphical format.
• 😀 The goal of creating an ERD is to help design and understand databases easily, facilitating communication between database developers and users.
• 😀 The system being modeled involves citizens submitting requests for public services such as creating ID cards (KTP), family cards (KK), and address change letters.
• 😀 The system enables citizens to submit applications online, making it accessible at any time and from any place.
• 😀 The ERD creation involves identifying entities like 'citizen,' 'application,' 'form,' and 'service,' with relationships defined between them, such as 'submitting' and 'filling out.'
• 😀 The 'citizen' entity has attributes like ID, name, address, email, phone number, photo, and family card number.
• 😀 The 'application' entity includes attributes like application number, application date, citizen ID, and service ID.
• 😀 The ERD also defines relationships with cardinality, such as a citizen making multiple applications, each having a single service or form associated with it.
• 😀 Admins or staff can process applications, print documents, and manage village news, which can be viewed by citizens, adding another entity 'news' to the diagram.
• 😀 Cardinality in relationships is indicated, such as 'many-to-many' between citizens and news and 'one-to-many' between citizens and application documents.

Q & A

What is an Entity Relationship Diagram (ERD)?

An Entity Relationship Diagram (ERD) is a visual representation of the data model that uses entities and relationships to represent the logical structure of a database. It helps in designing databases by providing a clear and graphical representation of how different entities are connected.

What is the purpose of creating an ERD for a public service information system in a village?

The purpose of creating an ERD for a public service information system in a village is to design a database that facilitates the management and processing of public service requests. It helps ensure that the system can manage various tasks such as citizen requests for services, document processing, and news management efficiently.

What entities are involved in the ERD for the public service system?

The main entities involved in the ERD for the public service system are: Penduduk (Citizen), Pengajuan (Application), Formulir (Form), Layanan (Service), Admin (Admin or Officer), Berita (News), and Surat/berkas Pengajuan (Letter/Document Submission).

What does the relationship 'Penduduk melakukan Pengajuan' mean in the ERD?

'Penduduk melakukan Pengajuan' means that a citizen (Penduduk) can make an application (Pengajuan) in the public service system. It represents the relationship between the citizen and the request they submit.

How is the relationship 'Mengisi' (Filling) represented in the ERD?

The relationship 'Mengisi' (Filling) is represented in the ERD as the action where a citizen (Penduduk) fills out a form (Formulir) when making an application (Pengajuan). This signifies that the citizen is required to provide information in a form for the application process.

What is the significance of 'Kardinalitas' (Cardinality) in the ERD?

Kardinalitas (Cardinality) indicates the maximum number of relationships between two entities. For example, 'Penduduk' can submit many 'Pengajuan' (applications), and 'Pengajuan' can only be associated with one specific 'Layanan' (service). It helps define the rules of data relationships and constraints.

Why is the attribute 'ID Penduduk' important in the system?

The attribute 'ID Penduduk' (Citizen ID) is important as it serves as the primary key for the 'Penduduk' entity. It uniquely identifies each citizen in the system and is used to link them to their applications and other related data.

What kind of data is stored in the 'Formulir' entity?

The 'Formulir' (Form) entity stores data such as the form number (nomor formulir), form type (tipe formulir), form date (tanggal formulir), and form title (judul formulir). These attributes define the specifics of each form used for applications in the system.

How does the 'Admin' entity interact with the system in the ERD?

The 'Admin' entity represents the administrators or officers who manage and process the applications submitted by citizens. Admins can process and print documents (Surat/berkas pengajuan), manage news (Berita), and handle various administrative tasks within the system.

What are the attributes of the 'Layanan' (Service) entity?

The attributes of the 'Layanan' (Service) entity include: Service ID (ID layanan), Service name (nama layanan), Service information (info layanan), and Service image (image layanan). These attributes describe the different services available in the public service system, such as creating KTP, KK, or processing other civil documents.
