Abstract
Currently, most of management systems adopt a query method of inquiring by use of certain one or multiple characteristics, such as names and time, of objects. Under many conditions, such characteristic attributes of the objects are same or similar, but the query result necessarily refers to multiple objects, and an original desired result is obtained only if query or manual screening is performed again by use of multiple judgment conditions, so that query is complicated and the query accuracy and the query speed are greatly reduced. DTREE refers to a simple and rapid method for displaying multi-level objects by use of a free form mode, and DTREE supports infinite classification, so that a DTREE mode is utilized to display objects in most of projects. The DTREE is combined with a traditional query mode, so that the query speed and the query precision are greatly improved.
Description
Technical field
The present invention relates to a kind of realization based on the express query method under DTREE multi-layer classification.The invention belongs to field of computer technology.
Background technology
At present, the querying method that most of management system adopts is inquired about, as name, time etc. by certain or certain several feature of object.And under many circumstances, these characteristic attributes of object are same or analogous, and the result of inquiry is inherently multiple object, multiple decision condition is at this time just needed to go inquiry or the artificial screening carried out again just can draw original desired result, Here it is, and inquiry becomes loaded down with trivial details, also greatly can reduce accuracy and the speed of inquiry.DTREE shows the simple and efficient method of of multi-layer object with Tree structure, and DTREE supports the classification of infinite stages, makes the mode that all can use DTREE in most of project go display object.DTREE is not generally used for inquiring about, because it needs operating personnel to go click to launch sub-menus, is used for carrying out profound level, the search efficiency of many condition is low-down.
Summary of the invention
Goal of the invention:
The defect existed for the above querying method and the essential characteristic of DTREE, if improved on the basis of DTREE, in conjunction with traditional querying method, the tree-like basis of DTREE is inquired about, some querying conditions can carry out on DTREE like this, can make like this when inquiry, to select screening conditions to become more simple, thus the degree of accuracy of inquiry and speed are increased considerably.
Concrete steps are as follows:
Step 1: the object of all required inquiries is integrated, stored in database according to tagsort classification.
Step 2: the object showing required inquiry in the mode of DTREE.
Step 3: on each node of DTREE, arranges the input frame needed for an inquiry.
Step 4: the input frame on each node is bound the rating information on this node, these specific inquiry screening conditions that just made the query frame on node have, then input information needed and inquire about in input frame.
Embodiment
Embodiment one
Use Myeclips 8.6 development platform to develop design, use expert data library software MySql to carry out data management.
1. adopt the user data of a community to implement, user carried out classification with cell area, unit and floor, then by data stored in database.
2. carry out classification display the user of Shang Ba community, interface with region, unit and floor with DTREE.js.
3., on each classification node of the community user of tree-like display, set an input frame.
4. setting inquiry in input frame, and the information of the upper current classifying screen point of binding, as the initial query screening conditions that this input frame is inquired about.
5., by selecting higher level's condition, inquiring about at Nodes, obtaining the specific user within the scope of this nodal information.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
Claims (3)
1. obtain object information, carry out classify and grading according to features such as class hierarchies, then by data stored in database.
2. on interface, object is shown with DTREE.js, and add input frame on node.
3. setting inquiry in input frame, and the information of the upper current classifying screen point of binding, as the initial query screening conditions that this input frame is inquired about, then inquired about by input frame input customizing messages.
