+1. **Time-Series Database (Apache IoTDB)**: The core component for time-series data storage, offering high compression, rich query capabilities, real-time stream processing, high availability, and scalability. It provides security guarantees, configuration tools, multi-language APIs, and integration with external systems for building business applications.
+2. **Time-Series File Format (Apache TsFile)**: A specialized storage format for time-series data, enabling efficient storage and querying. TsFile underpins IoTDB and AINode, unifying data management across collection, storage, and analysis phases.
+3. **Time-Series Model Training-Inference Engine (IoTDB AINode)**: A unified engine for intelligent analysis, supporting model training, data management, and integration with machine/deep learning frameworks.
 
-1. Time-series Database (Apache IoTDB): The core component for time-series data storage, it provides users with high-compression storage capabilities, rich time-series querying capabilities, real-time stream processing capabilities, and ensures high availability of data and high scalability of clusters. It also offers comprehensive security protection. Additionally, IoTDB provides users with a variety of application tools for easy configuration and management of the system; multi-language APIs and external system application integration capabilities, making it convenient for users to build business applications based on IoTDB.
 
-2. Time-series Data Standard File Format (Apache TsFile): This file format is specifically designed for time-series data and can efficiently store and query massive amounts of time-series data. Currently, the underlying storage files for modules such as IoTDB and AINode are supported by Apache TsFile. With TsFile, users can uniformly use the same file format for data management during the collection, management, application, and analysis phases, greatly simplifying the entire process from data collection to analysis, and improving the efficiency and convenience of time-series data management.
+## 2. IoTDB Architecture
 
-3. Time-series Model Training and Inference Integrated Engine (IoTDB AINode): For intelligent analysis scenarios, IoTDB provides the AINode time-series model training and inference integrated engine, which offers a complete set of time-series data analysis tools. The underlying engine supports model training tasks and data management, including machine learning and deep learning. With these tools, users can conduct in-depth analysis of the data stored in IoTDB and extract its value.
