S20, according to metadata base map and metadata figure layer metadata about load information to form and show metadata map.
Above-mentioned technical proposal of the invention solves the problems, such as the user experience in metadata management, by utilizing map
Technology strengthens the vision visualization capability of metadata to construct and show metadata map, imitates so that the user experience is improved
Fruit.
According to an embodiment of the invention, in step S20, using mode presented below at least one of show first number
According to map: metadata map is scaled, metadata Map roaming, is got a bird's eye view, flowing road name, traversal path, search positioning.Specifically,
Tradition is unable to satisfy the management and requirement of big data era magnanimity metadata based on the metadata user experience of menu mode,
In order to solve the problems, such as the user experience of the metadata map based on big data.The present invention has been created using Cartographic Technique as foundation
The displaying mode for the metadata map stated.Wherein, metadata map scaling includes: to realize putting for data map using mouse roller
Greatly, it reduces, can dynamically increase and decrease displaying content, it, can be certainly when metadata map zooms in or out the critical value of setting
It is dynamic to be switched to next figure layer；Metadata Map roaming, which refers to, realizes overflowing in metadata map by pulling metadata map
Trip；It gets a bird's eye view and refers on the thumbnail of map, carry out being switched fast for system；Flowing road name includes: to carry out metadata information
When browsing, corresponding node is chosen, the relevant attribute data of metadata, relation information can follow shift position synchronous with label information
Variation；Traversal path includes: the beginning and end condition according to setting, traverses whole nodes between beginning and end, as
Basis further realizes the conditional filtering of metadata；Search positioning includes: to realize metadata according to specified querying condition
Global search, and search result is positioned in map.
It in one embodiment, can be according to the classification of metadata, design element data map different classifications on showing specification
Legend specification.And it is possible to the user mode according to metadata map, the level legend of design element data map, color rule
Model, combining form etc..
According to an embodiment of the invention, metadata figure layer includes technology visual angle in the base map technical aspect of metadata map
Figure layer and business visual angle figure layer；Wherein, technology visual angle figure layer includes table figure layer and field figure layer, and business visual angle figure layer includes report
Figure layer and index figure layer.Each metadata is assigned with existing figure layer and coordinate, and the coordinate position is recorded in nodal community.
The figure layer at technology visual angle and business visual angle is set up to metadata map, technology visual angle subregion, system, table and field etc. four are big
Figure layer；Business visual angle is from figure layers such as region, system, report, indexs.Wherein, business visual angle and technology visual angle can be mutually communicated.
Member is given full play to from macroscopic view to microscopically focus information thus, it is possible to be classified and show the basic factors and management essentials of each figure layer
Data map shows characteristic.
According to an embodiment of the invention, the interaction technique of metadata map is in terms of metadata map interaction technique with member
Based on the base map of data map, mode is used in combination and shows specification, comprehensive a variety of front-end technology can allow user in front end
Metadata is analyzed, used and is shown with the user experience of map.
According to an embodiment of the invention, diagram data further includes metadata node relation information and label information.Correspondingly,
It include: traversal diagram data to realize metadata according to metadata base map and metadata figure layer metadata about load information in step S20
Metadata node traversal, metadata node relationship traversal (for example, consanguinity analysis, impact analysis, panorama analytical method) and label believe
Breath inquiry.Furthermore it is also possible to realize that global search, pattern match etc. are applied.
According to an embodiment of the invention, after traversing diagram data further include: according to the knot of metadata node relationship traversal
Fruit is analyzed.
As shown in Fig. 2, according to an embodiment of the invention, with additionally providing a kind of metadata visualization of knowledge based map
Figure building system, comprises the following modules:
Metadata service module, for obtain according to metadata generate diagram data, diagram data include metadata base map and
Metadata figure layer, metadata figure layer include for the figure layer of each data allocations, and metadata base map includes for each metadata point
The coordinate position matched；
Metadata application module, according to metadata base map and metadata figure layer metadata about load information to be formed and show member
Data map.
According to an embodiment of the invention, diagram data further includes metadata node relation information and label information.Also, first number
It is also used to traverse diagram data according to service module to realize metadata node traversal, metadata node relationship traversal and the mark of metadata
Sign information inquiry.Specifically, metadata service module can mainly include that diagram data traverses submodule, to realize the section of metadata
Point traversal, relationship traversal and tag queries function.The core function of metadata service module is that algorithm is realized, in the module,
Realize the dynamic generation of metadata map, relationship traversal (such as consanguinity analysis, impact analysis, panorama analytical method), label traversal,
Global search scheduling algorithm.
According to an embodiment of the invention, metadata application module can mainly include aphorama for metadata application module
Two function sub-modules of figure submodule and blood relationship impact analysis submodule.Panoramic view submodule combination metadata base map and first number
According to figure layer, divided according to the level of metadata, layer-by-layer dynamically load metadata information, realize metadata map level drill through, nothing
Damage scaling, data roaming, birds-eye view, flowing road name and search positioning function.
In addition, metadata application module can also be used to be analyzed according to the result of metadata node relationship traversal.Specifically
, the functions such as the blood relationship impact analysis, data downloading, secondary analysis of metadata can be realized by blood relationship impact analysis submodule.
In one embodiment, metadata map application process is as shown in figure 3, user directly accesses metadata application mould
Block, metadata application module can send transaction request to metadata service module and obtain data according to the needs of users.Metadata
Meeting calling figure data traversal module obtains the metadata letter stored in metadata storage module after service module receives transaction request
Breath, and return data to metadata application module.Metadata application module receive after data through panoramic view module and
Blood relationship impact analysis views module carries out data displaying.
In conclusion by means of above-mentioned technical proposal of the invention, bottom of the metadata service module based on metadata map
Figure and figure layer data realize the node traverses, relationship traversal and label of metadata using inquiring technology and diagram data traversal technology
Inquiry, and database service interface is provided.Metadata application module merges a variety of front end display techniques, by calling data service to connect
Mouth obtains base map and figure layer data, establishes the panoramic view and blood relationship impact analysis view of metadata map, by metadata
The form of figure realizes the interaction of metadata front end.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
