Embodiment Construction
[0015] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0016] method embodiment
[0017] figure 1 It is a flow chart of Embodiment 1 of the method for graphically displaying metadata relationships in the present invention. like figure 1 As shown, this embodiment includes:
[0018] Step 102: Use the metadata object to be analyzed as the output object to find the corresponding predecessor metadata object, and continue to use the predecessor metadata object obtained each time as the output object to search for other corresponding predecessor metadata objects until the corresponding When the predecessor metadata object is empty or other predecessor metadata objects are empty, stop the continuous execution operation, an...

The invention provides a method and a device for graphical display of metadata relationship, wherein the method comprises the following steps of: taking a metadata object to be analyzed as an output object so as to search corresponding precursor metadata objects, continuously executing, respectively taking the precursor metadata object searched each time as the output object to search the corresponding other precursor metadata objects, until the precursor metadata object is null, stopping operation and obtaining a first relationship linked list; taking the metadata object to be analyzed as an input object so as to search the corresponding successor metadata objects, continuously executing, respectively taking the successor metadata object searched each time as the input object to search the corresponding other successor metadata objects, until the successor metadata object is null, stopping operation and obtaining a second relationship linked list; and graphically displaying the relationship among the metadata objects according to the first relationship linked list and the second relationship linked list. The method and the device realize a high-readability metadata object flow diagram automatically built in the same flow diagram.
Description
technical field [0001] The invention relates to the field of metadata, in particular to a method and device for graphically displaying metadata relationships. Background technique [0002] In an enterprise-level data warehouse, there are many tables and programs involved. Through the concept and characteristics of metadata, the context relationship is described, and the relationship between objects is established by using metadata relationship analysis. Its relationship table can be described as a four-tuple object: [relationship name, input object, output object, conversion rule]. This data relationship plays an important role in the forward modeling, reverse engineering and program understanding of the data warehouse, which can help software engineers understand the warehouse system. [0003] The metadata-based automatic analysis program has established the relationship between the interface, table, program, field, and application to be analyzed for the system collection....
