GORM Golang Object Relational Mapping Distributed applications of the GORM ORM in computer science is a programming technique for converting data between incompatible type systems in OOP languages. This creates, in effect, a “virtual object database” that can be used from within the programming language.LINE SHOPPING needs to verify data and consistent tests in MySQL

VOS Verda Object Storage VOS (Verda Object Storage) is an object storage service with comes with an S3 compatible Object Storage API. The S3 API is a de facto standard object storage API for AWS S3, which means we can utilize open-source software based on S3 API for VOS without changing our source code. We can use the S3 SDK to manage VOS objects.
