atabase Systems and Knowledgebase Systems share many common principles. Data & Knowledge Engineering (DKE) stimulates the exchange of ideas and interaction between these two related fields of interest. DKE reaches a world-wide audience of researchers, designers, managers and users. The major aim of the journal is to identify, investigate and analyze the underlying principles in the design and effective use of these systems. DKE achieves this aim by publishing original research results, technical advances and news items concerning data engineering, knowledge engineering, and the interface of these two fields.DKE covers the following topics:1. Representation and Manipulation of Data & Knowledge: Conceptual data models. Knowledge representation techniques. Data/knowledge manipulation languages and techniques.2. Architectures of database, expert, or knowledge-based systems: New architectures for database / knowledge base / expert systems, design and implementation techniques, languages and user interfaces, distributed architectures.3. Construction of data/knowledge bases: Data / knowledge base design methodologies and tools, data/knowledge acquisition methods, integrity/security/maintenance issues.4. Applications, case studies, and management issues: Data administration issues, knowledge engineering practice, office and engineering applications.5. Tools for specifying and developing Data and Knowledge Bases using tools based on Linguistics or Human Machine Interface principles.6. Communication aspects involved in implementing, designing and using KBSs in Cyberspace.Plus... conference reports, calendar of events, book reviews etc.

數據庫系統和知識庫系統有許多共同的原則。數據與知識工程（DKE）促進了這兩個相關領域之間的思想交流和互動。DKE吸引了世界各地的研究人員、設計師、管理人員和用戶。期刊的主要目標是識別、調查和分析設計和有效使用這些系統的基本原則。DKE通過發布有關數據工程、知識工程和這兩個領域的接口的原始研究成果、技術進展和新聞項目來實現這一目標。DKE涵蓋以下主題：1、數據和知識的表示和操作：概念數據模型。知識表示技術。數據/知識操作語言和技術。2、數據庫、專家或基于知識的系統的體系結構：數據庫/知識庫/專家系統的新體系結構、設計和實現技術、語言和用戶界面、分布式體系結構。3、數據/知識庫的構建：數據/知識庫設計方法和工具、數據/知識獲取方法、完整性/安全性/維護問題。4、應用、案例研究和管理問題：數據管理問題、知識工程實踐、辦公室和工程應用。5、使用基于語言學或人機界面原理的工具指定和開發數據和知識庫的工具。6、在網絡空間中實施、設計和使用KBS涉及的通信方面。加上…會議報告、活動日程、書評等。
