Embodiment 1

[0039] like figure 1 As shown, it shows a medical data migration method provided by an embodiment of the present invention, the method can be applied to a data migration device, and the method can include:

[0040] S101: Analyze the database to be migrated, and obtain the primary key relationship and foreign key relationship of the database to be migrated;

[0041] S102: Construct a relational data unit according to the primary key relationship and the foreign key relationship of the database to be migrated;

[0042] Wherein, it should be noted that the data unit is a data set with a hierarchical relationship;

[0043] S103: According to the size of the data unit, migrate the data unit to HBase through distributed parallel computing.

[0044] It should be noted that the database to be migrated can come from multiple data sources and is stored in different data structures, so the database to be migrated has the nature of multi-source heterogeneity. Differences in data source...

Embodiment 2

[0054] based on figure 1 In the first embodiment shown, in the process of migrating data units to HBase, it may also include:

[0055] Establishing a first mapping relationship between the clinical path in the medical data and the data unit, and establishing a first ontology database according to the first mapping relationship;

[0056] It should be noted that since the data unit in Embodiment 1 can be constructed according to the medical service table, and the clinical path includes multiple path nodes such as registration, first visit, examination, diagnosis, hospitalization, doctor's order, and reexamination, each path node has It can correspond to at least one collection of multi-source heterogeneous data; for example, a path node medical order can include a collection of multiple databases such as symptoms, prescriptions, and medicines, so a path node can be considered as a data unit. Specifically for medical data, According to the multiple path nodes in the clinical pat...

Embodiment 3

[0066] Based on the same technical idea of ​​the foregoing embodiments, see image 3 , which shows a medical data migration device 30 provided by an embodiment of the present invention, wherein the device 30 includes: an analysis module 301, a construction module 302, and a migration module 303; wherein,

[0067] The analysis module 301 is configured to analyze the database to be migrated, and obtain the primary key relationship and foreign key relationship of the database to be migrated;

[0068] The construction module 302 is configured to construct a relational data unit according to the primary key relationship and foreign key relationship of the database to be migrated; wherein, the data unit is a data set with a hierarchical relationship;

[0069] The migration module 303 is configured to migrate the data unit to the distributed database HBase through distributed parallel computing according to the size of the data unit.

[0070] For example, see Figure 4 The medical ...

Abstract

Embodiments of the invention disclose a medical data migration method and apparatus. The method can comprise the steps of analyzing a to-be-migrated database to obtain a primary key relationship and a foreign key relationship of the to-be-migrated database; constructing a relational data unit according to the primary key relationship and the foreign key relationship of the to-be-migrated database; and according to the size of the data unit, migrating the data unit to a distributed database HBase through distributed parallel computing. According to the medical data migration method and apparatus provided by the embodiments of the invention, polymorphic heterogeneous medical data can be migrated to the distributed database intactly and consistently in a low-delay manner.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a medical data migration method and device. Background technique [0002] Medical data is a collection of all data related to medical and life health and generated by patients at various stages of medical care. Due to the complex types of medical data and various sources, medical data has a high degree of heterogeneity. However, medical data contains diverse and rich information value, and effective integration of medical data has significant advantages for doctors, hospitals, medical research institutions, health centers and patients. [0003] The current storage of medical data is based on relational databases and non-relational databases (NoSQL, NotOnly SQL) MongoDB, but the above-mentioned database types have obvious disadvantages when dealing with businesses related to massive big data, such as facing massive data. Efficient storage and access requirements, the current me...
