In a specific implementation process, according to a scientific research reagent consumable purchase management predetermined standard flow, a hospital resource planning system and a cloud platform agree on an intermediate form name and a data content format required by data interaction, and a corresponding data form is created in an intermediate database. In the actual data interaction process, the hospital resource planning system is directly connected with the intermediate database in a local adaptation manner to realize the synchronization of service request data (including data writing updating or query acquisition); the cloud platform proxies the service request through the edge computing platform to realize the synchronization of the service request data. In the data synchronization process, the consistency and real-time performance of the synchronized data are very important. In the application, the hospital resource planning system, the intermediate database and the edge computing platform all adopt relational data to transmit data. The consistency and real-time performance of the synchronous data are mainly guaranteed through the ACID characteristics (namely atomicity, consistency, isolation and durability) of the relational database. The hospital resource planning system and the edge computing platform adopt a polling or event-triggered strategy to drive data synchronization operation, generally speaking, data writing or updating operation is generally driven by a service request event, and data query and acquisition are generally driven based on a polling mode.
The embodiment ensures the consistency and real-time performance of the edge service data synchronization by adopting the ACID characteristics (namely atomicity, consistency, isolation and persistence) of the relational database.
In some embodiments, the scientific research reagent consumables are of various types, and some reagents cannot be directly made into data forms for interaction, so that the Web service can be directly proxied through the edge computing platform, and a user can directly access a relevant Web service page of the cloud platform in a hospital intranet; therefore, in this embodiment, not all data interaction is performed through the middle database, and a small amount of complex business interaction can directly go through the Web proxy service based on the edge computing platform.
The embodiment effectively solves the risk that the consumable supply purchase application data cannot be stored in the middle database.
