Database as one important research direction of materials genome initiative (MGI) has a meaningful role in the accelerated design of material. The material database was gradually developed worldwide since 1970s, and then a huge number of offline and online databases have been built up until now on. The basic function of early database is to store, manage and search data. With the concept of MGI put forward, material database begins to focus on a lot of advanced functions, such as data sharing, automatic collection and data output. Intelligent design platform for material based on the material database has been developed by online integrated computing software or program and data analysis software. Data mining is a process to find the valuable knowledge from the database without considering the complex mechanism of physics and chemistry. It plays an important role in material design in database or small data set. Data mining has been widely applied to the prediction and optimization of material properties, defects or quality prediction and production monitoring, recognition of microstructures. In future, the material database and data mining technology will be integrated tightly to satisfy the requirements of the integrated computing and intelligent material design.
