The invention discloses a distributed log management method and a distributed log management system, belongs to log file management, and aims to solve the technical problem of how to realize log management and log query in a distributed manner. The method comprises the following steps: collecting log files of each independent service system based on a unified request Id, and connecting the distributed log files in series; storing the log files in a document-oriented database, and constructing an index cluster in the database, wherein each index in the index cluster corresponds to one log file;interacting with a user through a web page, and matching the web page with a database through an image interface to realize data query and data display. The system comprises a log acquisition module,a storage search module and a query display module.

The invention discloses a material management method and device. Through the material management method and device, forms of target materials can be determined according to the target materials, so that information and current states of the materials and an operation instruction initiated on the target materials are acquired through the forms corresponding to the target materials. According to themethod, after the operation instruction is initiated, the forms are modified according to the instruction to comprise basic information, states and an operable instruction of the target materials after the operation instruction is executed. In this way, relevant content of each target material is recorded in the form corresponding to the target material, distributed management of the materials can be realized, and therefore management of each material is simplified; meanwhile, the materials can be fully tracked through the current states, recorded in the forms, of the target materials, that is, the link of the materials can be determined visually through the current states of the target materials; and moreover, whether receiving of the materials is confirmed can be confirmed through the operable instruction, and therefore the disagreement of whether a receiver borrows the materials is avoided.
