在现有的镁合金数据库系统查询功能的基础上，深度分析用户需求，结合数据库查询系统的设计特点，利用ASP技术和DreamWeaver网页制作工具，对查询模块的效率和查询方式进行优化。提高镁合金数据库的查询效率，增添了镁合金相图、镁合金组织等查询模块，丰富数据库的查询内容及镁合金材料数据库的性能优化方案，提高了数据库的实用性。

Based on an existing magnesium alloy database, a query system is optimized by considering the design characteristics, and an integrated query system for this magnesium alloy database is developed to meet the demands of more users. The result shows that the new system improves the query efficiency of the magnesium alloy database, especially for queries concerning phase diagrams and the structure of magnesium alloys. This means that the new system provides users a more powerful and useful magnesium alloy database.
