The invention relates to the field of data storage, in particular to a data model and view standardization method and system based on a DBVC (database virtual machine) framework.
Background
In our daily life, work and study, various kinds of information are generated all the time, and the information needs a certain carrier to be stored after being generated, and the database plays an important role in the information. The database is a warehouse for storing data, and the warehouse organizes, stores and manages the data according to a data structure set by people, so that the data can be more conveniently reserved and used. In the current era of and with computing and big data, more and more non-relational databases are emerging. According to different data storage positions, the database is divided into a disk database and an in-memory database from a large direction. Compared with the disk database, the memory database mainly has the advantages of easy expansion, low cost and higher advantages than a relational database in the fields of high performance, high concurrency and rapid service development.
The MVC (Model: service data and service logic at the same time; View: Model visualization through UI component of platform; Controller: receiving user operation, modifying Model and refreshing View) framework is a software design Model, codes are organized by a method of separating service logic, data and interface display, the service logic is gathered into a component, and the service logic does not need to be rewritten while the interface is improved and customized and the user interaction is carried out.
With the rapid development of Internet technology, the software development based on the MVC design pattern is widely applied in the design and implementation processes of application systems, and the MVC design concept has many advantages, but also has the following disadvantages:
(1) MVC and the improved framework thereof do not have a unified standard for establishing a data model, and only separate business logic from views in different modes, but have larger workload for coding the data model and the views, thereby having higher requirements on developers;
(2) MVC is developed in a desktop application era, a data model is mainly subjected to data synchronization with a local file or a relational database, the structuralization of the data model is emphasized, and the requirements of unstructured and unpredictable data are difficult to process;
(3) although the view can be independent of data and service changes, the view layer is difficult to standardize due to the fact that a data model is not standard, and only the data and the service are not influenced but are influenced by the data and the service.
Disclosure of Invention
The invention aims to provide a data model based on a DBVC (database video coding) framework, a view standardization method and a view standardization system, aiming at solving the problems that the view layer cannot be standardized due to the fact that the data model of the conventional MVC framework has no unified standard and the like.

s2, establishing a data model agent through data model instance nodes, and performing addition, deletion, modification and query operations on the attributes of the instance;
s3, associating the view with the data model by configuring the view information;
and S4, assembling through multiple views, and displaying the data model.
Further, the step S3 further includes the following sub-steps:
s301, configuring data query information of the view;
s302, configuring data attribute information of the view;
s303, acquiring a data node from a database according to the view data query information in the step S301, and acquiring a child node as a parameter from the data node according to the view data attribute information in the step S302;
and S304, taking the parameters as the interface refreshing parameters of the view.
Further, when the data querier queries the data nodes in the memory database, the data querier searches through the following two non-sequential execution modes:
A. accessing the value through a path formed by keys from the node where the value is located to the root node;
B. and performing query filtering statistical operation through SQL statements.
Further, the step A is used for querying the nodes of the non-array type; the step B is used for inquiring the group type node.
Further, the assembly of the view in step S4 is performed by a visual editor, and editing and generating a configuration are performed, and the assembly is completed at runtime.
A DBVC framework-based data model, view normalization system, comprising:
a data persistence layer: loading and storing the memory database;
