Mengenal Star Schema Di Data Warehouse Design a star schema for such a data warehouse clearly identifying the fact table and dimension tables, their primary keys, and foreign keys. also, mention which columns in the fact table represent dimensions and which ones represent measures or facts. step 1: identify the business process to model in order to identify the fact table. The star schema is a popular data modeling technique in data warehousing because it is easy to understand and query. the simple structure of the star schema allows for fast query response times and efficient use of database resources. additionally, the star schema can be easily extended by adding new dimension tables or measures to the fact.
Mengenal Star Schema Di Data Warehouse Star schema adalah metode pemodelan data yang efektif dan sering digunakan dalam data warehouse untuk mengatur data secara terstruktur dan mudah dipahami. dalam model star schema data warehouse, data disimpan dalam sebuah tabel fakta sentral yang berisi berbagai ukuran yang relevan, dikelilingi oleh tabel tabel dimensi yang menjelaskan detail. Erd or entity relationship diagram is a data model that displays the structure and relationships between entities. star schema is one of the most popular forms of data warehouse modeling. called star schema or star schema because the arrangement of the schema is similar to a star. this scheme is very popular and easy to implement for 1 subject.
