“…Kesalahan dalam mendesain ERD dapat terjadi karena kurangnya pemahaman awal mengenai komponen apa saja yang ada dalam ERD, masih bingung mengenai apa itu entitas, atribut dan tidak tahu hubungan apa antar entitas yang ada [24]. Bahkan dapat terjadi kesalahan dalam menyimpulkan ERD karena kurangnya memperhatikan detail dari sebuah database yang ingin dibuat.…”

There are many techniques used in database design. One of them is entity relationship diagram technique. ERD is one of the main diagrammatic representations of the conceptual data model that reflects the data requirements of users in a database system. ERD is also the first stage in database design. There are several things that must be considered in making an ERD for database design including, each database must have entities that are interconnected by relationships and each entity must have attributes consisting of a primary key as a characteristic of the entity and descriptive attributes. Many users have failed to create a database due to errors in the ERD creation. These errors can be conceptual errors, procedural errors, or technical errors. Therefore, this paper was made using the SLR method, namely by reviewing various kinds of references that discuss database design and then drawing conclusions, to make it easier for users to overcome problems that occur when making ERD and when implementing it.

Venn diagrams group data sets based on relations, either in the form of combined or slice sets. Venn Diagram mapping occurs when there are interrelated data sets. Weaknesses Venn diagrams do not show interconnected data, such as how many data records come from sorting Query data. In this study, cross-tabulation supports indicating related data in the database, making a Venn Diagram. This research uses cross-tabulation results to facilitate Venn Diagram mapping in database exploration. The variable used as experimental material is student test scores. Database interpretation has evidenced cross-tabulation to map Venn Diagram by separating Grade levels. The breakdown of Grade levels makes it easier to understand the visualization of data in the Venn Diagram. Merging Assignments, UTS, and UAS workable if they have the same goal, referring to the Grade as the data centre. The results obtained that the Grade value with the highest achievement is A-. Assignments worth >= 81.5 by 41%, UTS between values of 73-85.5 by 21%, and UAS between values of 77.5-82.5 by 24%.
