Benefits of using flexible data structures in relational databasesĮven in open source database systems like PostgreSQL we can store data without a predefined structure. It contains three collections linked by references.Īnother option is to embed documents into the collection. Here you can see the model created for MongoDB. A feature that ensures that data will only be stored if it is in the expected format. Other advantages: if you work with the MongoDB database, you can use the schema validation. Yes, you ou can also use a data modeling tool for noSQL databases like Moon Modeler for this purpose. Which way is more convenient? Try to model both and discuss with your colleagues. For example, in MongoDB you can create multiple collections and use references, or insert data into a selected collection as nested documents.

There are a number of options for how to store the data and how to model the schema. Whether you need to achieve a certain performance, etc. Of course, the design of the database structure depends on your needs, on whether you need to read the data frequently or only rarely.

Having one big closet where all the clothes will be placed indiscriminately is possible. Therefore, having a well-described database structure is very useful. A data model is used for better communication within the development team. Recall that one of the benefits of data modeling is the description of structure, the creation of documentation. The popularity of database systems such as MongoDB is obvious, and when it comes to the flexibility of saving data, this is certainly one of many key features. MongoDB schema design and noSQL database modelingīut what is the advantage of data modeling when we talk about noSQL databases? The advantage of many “schema-less” databases is that they are very flexible and it is not necessary to have a precise database structure. Better communication between team members.Easy and fast design, especially in the early stages of development.(Read more information about ER diagrams). In the case of relational databases, we can mention the creation of entity-relational diagrams in which entities, attributes and relationships between entities are displayed. Data modeling is the process of visually creating a graphical representation of a system or database.
