Core Viewpoint - The implementation of Data Agents appears straightforward but is fraught with challenges, primarily due to software engineering difficulties. A unified semantic layer is crucial for success, and neglecting aspects like scenario focus, iterative technical frameworks, or semantic models can lead to stagnation in prototype stages [2][6][12]. Group 1: Importance of Semantic Layer - The significance of building a semantic layer for Data Agents is widely recognized, with both domestic and international investments increasing in this area. Tencent Cloud WeData has been an early investor in this domain [7][12]. - The semantic layer encompasses four main aspects: concepts, data relationships, metrics, and dimensions, which are essential for providing accurate and unified data access interfaces for Agents [8][12]. Group 2: Technical Challenges and Solutions - The primary technical challenges in integrating Data Agents into existing enterprise platforms include data governance issues and the difficulty in evaluating the effectiveness of Data Agents [14][15]. - To address these challenges, a focus on specific scenarios for unified semantic layer construction and evaluation systems is recommended [15][18]. Group 3: Future of Data Roles - Data Agents are not expected to replace data engineers or scientists but will automate some execution tasks. This will lead to a fusion of roles, requiring professionals to possess a broader skill set related to Agents and large language models (LLMs) [10][11]. - Understanding the basic principles of Agents and LLMs is essential for effectively utilizing large model technologies [11]. Group 4: Recommendations for Enterprises - Companies are advised to focus on scenario-specific semantic abstraction and address existing data governance issues to build a robust semantic layer [16][17]. - It is crucial to establish an iterative technical framework and a comprehensive Agent operation system to monitor, evaluate, and modify the Data Agent effectively [18].
