Introduction

GraphQL has become a prominent technology in implementing data APIs. It provides a convenient and intuitive approach for querying data. Let’s look at a sample use case using the  Ballerina programming language and see how GraphQL compares to other traditional approaches such as implementing REST-style HTTP APIs. 

Use Case: E-commerce Data Query

Let’s take a typical e-commerce scenario of processing orders in an online store. The entity-relationship diagram below shows a typical representation that can be used in a relational database. This is of course a simplified representation of a real-life implementation. 

One approach for exposing such a data set would be to create a service with operations for each database table. This would be similar to the following.

• getOrder(id): OrderInfo
• getCustomer(id): CustomerInfo
• getShipper(id): ShipperInfo

In this article, look at different ways to test microservices and how you can have a suitable testing strategy to begin with.

This article describes the nature of microservices applications, contrasts them with monolithic apps, and talk about microservices in data management.
