What is External Data Definition?

External Data Definition (EDD) is a software development process that allows developers to define the structure and content of data outside the code. In other words, EDD provides a way to define data in a separate file or database, which can be referenced by the code without hard-coding the data into the application. This approach separates data from code, making it easier to manage, modify, and reuse data across different applications.

Why EDD is Important?

EDD is important because it helps developers to build applications that can adapt to changing data requirements without modifying the code. This means that developers can focus on building the application logic, while data specialists can focus on managing and updating the data. EDD also promotes data consistency and reduces coding errors, as developers can reference data definitions instead of typing them manually.

How EDD Works?

EDD works by defining data structures and content in a separate file or database, which can be accessed by the application at runtime. The data definition file or database contains information about the data types, fields, relationships, and constraints. The application references this file or database to read, write, and validate data. When the data changes, the data definition file or database is updated, and the application automatically adapts to the new data structure.

Data Types

Data types define the format and range of values that can be stored in a field. Examples of data types include text, number, date, boolean, and enumeration. Data types can also be customized to fit specific needs.

Fields

Fields define the attributes of a data record, such as name, age, address, and email. Fields can be grouped into tables, and tables can be related to each other to form a database schema.

Relationships

Relationships define the associations between tables, such as one-to-one, one-to-many, and many-to-many. Relationships are important for data integrity and consistency.

Constraints

Constraints define the rules that must be followed when inserting or updating data. Examples of constraints include unique, not null, default, check, and foreign key. Constraints help to prevent data errors and maintain data quality.

Benefits of EDD

The benefits of EDD include:

Separation of Concerns

EDD separates data from code, allowing developers to focus on application logic and data specialists to focus on data management. This separation of concerns improves collaboration, reduces errors, and enhances scalability.

Flexibility

EDD allows applications to adapt to changing data requirements without modifying the code. This flexibility makes it easier to maintain and extend applications over time.

Consistency

EDD promotes data consistency by providing a centralized definition of data types, fields, relationships, and constraints. This consistency improves data quality and reduces coding errors.

Reuse

EDD enables data to be reused across different applications, reducing duplication and improving efficiency. This reuse also promotes standardization and interoperability.

Examples of EDD

Examples of EDD include:

XML Schema

XML Schema is a language for defining the structure and content of XML documents. XML Schema provides data types, elements, attributes, and constraints for XML data.

JSON Schema

JSON Schema is a vocabulary for JSON documents that defines the structure and content of JSON data. JSON Schema provides data types, properties, and constraints for JSON data.

Relational Database Schema

A relational database schema is a collection of tables, fields, and relationships that define the structure and content of a database. Relational database schema provides data types, fields, constraints, and relationships for data.

OpenAPI Specification

The OpenAPI Specification is a standard for defining RESTful APIs. The OpenAPI Specification provides data types, parameters, responses, and constraints for API data.

Conclusion

External Data Definition is an important software development process that separates data from code, promotes data consistency, and enables application flexibility and reuse. EDD provides data types, fields, relationships, and constraints that can be defined in a separate file or database, making it easier to manage, modify, and reuse data across different applications. Examples of EDD include XML Schema, JSON Schema, relational database schema, and OpenAPI Specification.
