Engineering data management method and system

The invention provides an engineering data management method and system. The method comprises the following steps of acquiring the operation request information of pre-imported engineering data information; determining a required metadata source from a pre-established metadata base, engineering data in the metadata source are called; converting the engineering data into corresponding project entities; and determining an engineering project entry corresponding to each project entity in the project entities based on a pre-established corresponding relationship between the project entities and the engineering project entries, and finally executing corresponding operation according to the metadata type, the keywords and the engineering project entries corresponding to the operation informationto determine an operation result corresponding to the operation information. According to the present invention, the engineering data are entered in advance, and when a subsequent user carries out corresponding operation on
