EJDB 2.0 is a robust, embeddable JSON database engine designed to enhance data management in C/C++ applications. This guide will walk you through how to use EJDB 2.0, including installation, integration with different platforms, and tips on troubleshooting issues that may arise.

Getting Started with EJDB 2.0

Setting up EJDB 2.0 is straightforward. Follow these steps:

1. Installation

• Ensure you have CMake v3.24 or higher installed.
• Clone the EJDB repository and build from sources with the following commands:

git clone --recurse-submodules git@github.com:Softmotionsejdb.git
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make install

2. Platform Integration

EJDB 2.0 supports a multitude of platforms, including:

• macOS
• Android
• Flutter
• React Native
• iOS

Understanding the Code with Analogy

Imagine you’re managing a large library of books (JSON documents) where each book contains various chapters (data fields). EJDB allows you to easily organize, retrieve, and update these books.

Here’s how it works:

• Each book (JSON document) is stored neatly in a shelf (collection) and can be indexed for easy access.
• You can search for books by their title or even by the author’s name without messing up the library’s organization.
• Just as you can add new books or remove old ones from the library, you can easily modify, update, or delete JSON documents in EJDB.

Using the JQL Query Language

EJDB features a simple yet powerful query language called JQL (JSON Query Language), which allows for efficient querying and updating of JSON documents.

For example, you can retrieve a book by its title:

k query books title == "Your Book Title"

Troubleshooting

As with any technology, issues may arise while working with EJDB 2.0. Here are a few common problems and their solutions:

• Problem: Unable to connect to the database.
  Solution: Check if the HTTP server is running on the correct port and that the network address is accessible.
• Problem: Creates or updates fail with error messages.
  Solution: Ensure you have the correct permissions set for the database file and that your JSON syntax is valid.
• Problem: No response from queries.
  Solution: Verify your query syntax and parameters are correct.
