Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
In light of the foregoing problems in the prior art, there is now provided a domain model data management system a connected to a database system B and configured to manage domain model data stored in the database system B.
Specifically, the structure of the domain model data management system as shown in fig. 1 includes:
the self-association unit A1 is used for performing self-association operation of the upper and lower level relations on the domain model data to form self-association relations among different domain model data;
and the sequencing control unit A2 is connected with the self-association unit A1 and is used for simultaneously carrying out corresponding editing operation on other field model data having self-association relation with the field model data when carrying out editing operation on the field model data.
Specifically, in this embodiment, the domain model data management system is used as a management system independent from the database system, an independent meta-function layer is opened up outside the database system, and the corresponding domain data model object can implement interfaces of various meta-functions, thereby implementing a pluggable and universal tree structure management function, and the specific implementation manner will be described in detail below.
In this embodiment, first, the self-association unit a1 performs a top-bottom level relationship self-association operation on the domain model data stored in the database system, so as to associate different domain model data according to a top-bottom level relationship, thereby forming a self-association relationship between different domain model data.
Subsequently, the sort control unit a2 can be used to perform a data editing operation on the domain model data stored in the database system. Because the domain model data is associated with the upper-level relation and the lower-level relation in the previous self-association operation, the currently operated domain model data and the associated other domain model data can be simultaneously edited during the data editing operation, and the problem of data management confusion caused by the missed operation of the associated data is avoided.
In a preferred embodiment of the present invention, the self-association relationship of the domain model data obtained by performing the self-association operation in the self-association unit includes hierarchical relationship information and depth information of the domain model data, and the domain model data are associated with each other by establishing a tree structure;
the hierarchical relationship information is used for representing the hierarchical relationship between the field model data;
the depth information is used to represent a node depth at which the domain model data is associated with the tree structure.
Specifically, in this embodiment, a so-called hierarchical relationship, that is, a top-bottom relationship, is used to describe an interdependence relationship between the domain model data. In a tree structure, the hierarchical relationship is the relationship between a parent node and a child node. In this embodiment, the hierarchical relationship is represented by naming a specific attribute syscode _ FunPO after implementing the PO object of the self-associated meta-function interface in the self-associated unit.
In the present embodiment, the depth information is used to indicate the node depth of the tree structure associated with the domain model data. The node depth is actually used to indicate that each domain model data is located on the node of the second level in the whole tree structure. In this embodiment, the self-associated depth information is represented by stating a specific attribute depth _ FunPO behind the PO object implementing the interface.
Further, in a preferred embodiment of the present invention, as shown in fig. 2, the self-association unit a1 specifically includes:
a first self-association module a11, configured to establish a self-association relationship between domain model data having a tree structure and corresponding domain model data having a node structure;
the domain model data having a tree structure is used as parent node data, and the domain model data having a node structure is used as child node data.
Specifically, in the present embodiment, the domain model data having a tree structure may be regarded as parent in a tree form, and the domain model data having a node structure may be regarded as child in a node form, that is, after parent self-associates to form a self-associated tree structure, self-associates with a child node. The relationship of the combination is similar to the relationship of departments and persons, namely, a sub-level department is arranged under a department, persons are arranged under the department, and the persons serve as leaf nodes.
Also taking the department and person relationship as an example, in designing the relationship between the department and the person, an intermediate association entity class OrganEmpRel is designed, the roles of the IselRelParent _ PO, Ichaldren _ PO and Ichaldren _ PO interfaces are introduced to represent the relationship between the parent level and the child level, Organ is adopted to realize the IselRelParent _ PO, meanwhile the IselRelChildren _ PO inherits the self-association element function interface, and Emp realizes the Ichaldren _ PO, and the whole design relationship diagram is shown in FIG. 3.
In a preferred embodiment of the present invention, as still shown in fig. 2, the self-association unit further includes:
the second self-association module A12 is used for establishing self-association relationship between the domain model data with the node structure and the corresponding domain model data with the attribute structure;
the domain model data having a node structure is used as parent node data, and the domain model data having a tree structure is used as child node data.
Specifically, in the present embodiment, the domain model data having a node structure is a parent in a node form, and the domain model data having a tree structure is a child in a tree form, that is, the child is self-associated with the parent node after the child is self-associated to form a self-associated tree structure. The relationship of this combination is similar to the relationship of a role under which there is a menu and a sub-menu under which the menu is the final node.
Also taking roles and menus as examples, an intermediate association entity class rollemeulei can be designed, and interface roles of IParent _ PO and ISelfRelChildren _ PO are introduced to represent the relationship between a parent level and a child level, Role realizes IParent _ PO, Menu realizes ISelfRelChildren _ PO, and iselrelchildren _ PO inherits a self-association element function interface iselrelchildren, and a design relationship diagram of the intermediate association entity class rollemeulrel is shown in fig. 4.
In a preferred embodiment of the present invention, as still shown in fig. 2, the self-association unit a1 specifically includes:
and a third self-association module A13, configured to establish a self-association relationship between the domain model data having the node structure.
Specifically, in this embodiment, the third self-association module a13 is used to establish a parent-child relationship between two domain model data that are both nodes. The relationship of such a combination is relatively simple, for example a relationship of a character to a person, with no other sub-characters under the character, nor other sub-persons under the person.
Still taking the relationship between roles and people as an example, an intermediate association entity type rollerel is designed, and interface roles of IParent _ PO and IChildren _ PO are introduced to represent parent-child relationships, where Role implements IParent _ PO and Emp implements IChildren _ PO, and a design relationship diagram under this embodiment is shown in fig. 5.
In a preferred embodiment of the present invention, a self-association unit a1 may include the first self-association module a11, the second self-association module a12, and the third self-association module a13 at the same time, that is, the three self-association modes described above are provided at the same time, so as to form a relatively complete tree structure, which includes various hierarchical relationships that may exist between domain model data.
In a preferred embodiment of the present invention, as still shown in fig. 2, the self-association unit a1 may further include:
the searching module A14 is used for searching a set of all child nodes under preset domain model data in the database system;
a removing module a15, configured to remove, from the database system, domain model data corresponding to leaf nodes under preset domain model data;
the adding module a16 is configured to add, to the database system, the domain model data corresponding to the child node under the preset domain model data.
Specifically, in this embodiment, after defining the relevant operation interface, the self-association unit a1 may implement functions of searching, removing, adding, and the like.
When searching for a specific object, all subsets under the specific object, i.e. the combination of all child nodes (excluding the specific object itself), may be searched, and the search for the subsets may be performed in ascending order of depth.
When the child object of the specified object is removed, the child object is allowed to be removed if the child object is a leaf node, and is not allowed to be removed otherwise. While also supporting the addition of child objects for a given object.
The design implementation diagram of the self-correlation unit is shown in fig. 6.
In a preferred embodiment of the present invention, as shown in fig. 7, the sorting control unit a2 specifically includes:
a moving module A21, configured to, when moving the domain model data, simultaneously move the corresponding other domain model data according to the self-association relationship of the domain model data;
and the editing module A22 is used for editing the corresponding other domain model data simultaneously according to the self-association relation of the domain model data when editing the domain model data.
Specifically, in this embodiment, the PO object implementing the sort control meta-function interface must be named a specific attribute sort _ FunPO. Since the domain model data has been subjected to the self-association operation in the previous self-association unit a1, the above specific attributes can be automatically maintained at the time of sorting, thereby realizing association editing at the time of sorting control.
Specifically, for example:
1) in the sequence control process of the movement module a 21:
if the data of one domain model needs to be moved upwards, the data in all the child nodes of the domain model data can be moved upwards simultaneously according to the self-association relation of the domain model data;
if a certain field model data needs to be moved down, the data in all the child nodes of the field model data can be moved down simultaneously according to the self-association relationship of the field model data;
the "move up" and "move down" operations described above both refer to moving data to different nodes in the tree structure, i.e., changing the self-association relationship between the data.
2) In the sort control process of the editing module a 22:
data in child nodes of the domain model data can be correspondingly increased according to the self-association relation of the domain model data if certain domain model data needs to be added;
if a certain field model data is required to be deleted, the data in all the child nodes under the field model data can be correspondingly deleted according to the self-association relation of the field model data;
and if the numerical value of certain field model data needs to be modified, the numerical value of data in the sub-node in the field model data can be correspondingly modified according to the self-association relation of the field model data.
And querying certain domain model data, wherein the self-association relationship of the domain model data can be obtained.
The design implementation diagram of the sequencing control unit A2 is shown in FIG. 8.
In summary, in the technical solution of the present invention, a management system is independently arranged outside a database system, and the domain model data in the database system is subjected to self-association operation according to the hierarchical relationship thereof, so as to form a tree structure of the domain model data, and when data editing and operation are performed, association editing or operation is performed according to the tree structure, so as to implement association editing and processing on the domain model data, and avoid the problem of data management confusion caused by data editing.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
