EdgeDB can be defined as an object-oriented database management system. Data is defined as object types, and these types are defined with attributes and methods. In this article, a detailed explanation will be provided about the object type in EdgeDB. The object type is one of the object types in EdgeDB. An EdgeDB object can be thought of as a class, and these objects have attributes and methods. The object type defines the characteristics of an object type by keeping these attributes and methods together.

Edgedb offers a data type called range, which represents a range or numerical interval. The range data type is very useful for mathematical or numerical operations, and is commonly used in database queries. The range data type is expressed as range<T>, where T represents the data type used in the range. The range data type represents an interval between two values and can be defined for a specific data type. For example, the range<int64> data type represents a numerical interval between two int64 numbers.

Edgedb is a modern database that supports the tuple data type. Tuple data type is used to represent combinations of different data types and this data structure can contain named or unnamed elements. The Tuple data type is used to store combinations of multiple different data types. In edgedb, the tuple data type is defined using the keyword tuple. The following example defines an unnamed tuple instance, which contains a str and an int64 element:

The array data type is used to store multiple data elements in a single data structure. In edgedb, the ‘array of’ syntax is used to define arrays. For example, the following example defines an array named colors which contains color names of type str: CREATE TYPE Product { required property name -> str; required property colors -> array of str; }; INSERT Product { name := "T-Shirt", colors := ["Red", "Green", "Blue"] }; SELECT Product.

Edgedb allows users to define enums and use them in data modeling. Enums are one of the data types we use to store data. An enum is a data structure that contains a specific set of constant values. These constants can be used to limit the values of a field in the data model. This can help prevent storing incorrect or invalid data in the model and provide application developers with a more precise and secure data modeling experience.

EdgeDb is an open-source, relational database management system (DBMS) and a next-generation Object-Relational Mapping (ORM) tool. It is developed as part of PostgreSQL and designed to be used with Python. EdgeDb is designed to provide higher performance, less code, and better security compared to PostgreSQL. The history of EdgeDb began in 2018 when it was initiated by MagicStack, a software company based in Russia, with the aim of providing a better tool for developing and managing database applications.
