Method, device and system for storing and reading list data

Abstract

The invention discloses a method for storing and reading list data, comprising the following steps of list data storing and list data reading, wherein the list data storing step comprises the following steps of: receiving list data submitted by a user, converting the list data into a JAVA object, serializing the JAVA object into an XML (Extensible Markup Language) character string by using an open source item XStream, compressing the XML character string into byte arrays, and storing the byte arrays into a databank; the list data reading step comprises the following steps of: reading the byte arrays from the databank; decompressing the byte arrays into the XML character string; deserializing the XML character string into the JAVA object by using the open source item XStream, and converting the JAVA object into the list data. In the invention, a list is used as a whole, after JAVA is objectified, the JAVA object is serialized into the XML character string by using the open source item, and the XML character string supports the storage of various databanks and is simple to store.

Description

technical field [0001] The present application relates to the field of databases, in particular to a form data storage and reading method, device and system. Background technique [0002] The structure of form data is diverse. For different forms, different data tables and access programs need to be designed for storage and retrieval. Once new data items are added to the form, the table structure and stored procedures need to be adjusted, but in practical applications, user needs are always changing, and the data items in the form are continuously added and adjusted, resulting in continuous modification of the table structure , expansion, and the corresponding data storage program is constantly modified, which brings a lot of maintenance workload and also brings great hidden dangers to the stability of the application system. [0003] In the application system, it is often required for auditing. It is required to have a historical version control function for some business ...

Problems solved by technology

At the same time, for security reasons, some sensitive data must not be stored in plain text, and must be converted into information that cannot be directly seen for storage.

[0004] It can be seen from the above introduction that in the existing form data storage process, due to the diversification of the form data structure, different structured tables need to be established to store the form, the storage process is difficult, and the corresponding process of reading the form will also be complicated and difficult; in addition Poor security of stored procedures
