基于Intersystems IRIS平台整合医院信息查询业务解决方案

概述：

随着医院信息化建设的逐步完善，医院子系统越来越多，系统间接口越来越多，同时接口费用不断增加，管理工作变得越来越复杂。其中，查询类业务接口根据业务类型分化，数量也是逐步递增，带来接口量大、开发工作繁重、代码冗余、维护困难等等问题。针对这一困境，我们基于Intersystems IRIS数据平台整合医院信息查询业务解决方案。该应用程序可通过配置完成查询业务接口实现，大大缩小开发、维护、实施等项目关键运转周期。

关键应用：IRIS、REST API、ObjectScript、Globals 、SQL、DATA LOOKUP TABLES、JDBC、BPL、Model

技术细则及应用介绍：

1. 技术细则
   1. Globals (key-value)
      Globals是可以在IRIS数据库中存储和管理的稀疏多维数组。您可以使用ObjectScript和本机API处理Globals。
      工具:
      https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GGBL_MANAGING
      应用：
      应用程序根据Globals的键值对、访问速度快的特性。应用在本次程序的Rest分派类与BP流程管理中取值应用，解决了频繁取值速度慢、实现在查找表前端页面配置操作，如：存储了SQL模型、服务配置信息等等。

   2. SQL访问
      InterSystems IRIS通过 ObjectScript、REST API及JDBC提供对数据的SQL访问.
      工具:
      https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=GSQL_smp
      应用：
      在查询业务中，三方系统不配合接口改造，导致接口实现困难问题。此时，我们采用IRIS内嵌模型ObjectScript、REST API及JDBC来实现对数据的SQL访问，来建立业务接口。

   3. Object访问
      通过ObjectScript、REST API，InterSystems IRIS提供了在Globals 存储和更改对象实例的途径。
      文档：
      https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=PAGE_multimodel_object
      应用：
      在整个交互过程中，直接操纵InterSystems IRIS对象。ObjectScript类定义通常用作创建对象（例如患者，科室或医护人员）的模板。

English Description

Integration of hospital information query business solution based on InterSystems iris platform

Summary:

With the gradual improvement of hospital information construction, there are more and more hospital subsystems, and more and more interfaces between systems. At the same time, the interface cost is increasing, and the management work is becoming more and more complex. Among them, the number of query business interfaces is gradually increasing according to the business type differentiation, which brings problems such as large amount of interfaces, heavy development work, code redundancy, difficult maintenance and so on. In view of this dilemma, we integrate the solution of hospital information query business based on InterSystems iris data platform. The application can be configured to complete the query business interface implementation, greatly reducing the key operation cycle of development, maintenance, implementation and other projects.

Key applications: iris, rest API, ObjectScript, globals, SQL, data lookup tables, JDBC, BPL

Technical details and Application Introduction:

1. Technical details

   1. Globals (key-value)
      Globals is a sparse multidimensional array that can be stored and managed in IRIS database. You can use ObjectScript and native APIs to work with globals. Tools:
      https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GGBL_MANAGING
      Application:
      According to the key value pair of globals, the application program has the characteristics of fast access speed. It is applied in the rest dispatch class and BP process management of this program, which solves the problem of frequent value taking, slow speed and configuration operation on the front page of the lookup table, such as storing SQL model, service configuration information and so on.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/Rest/Handler.cls
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/BP/QueryManage.cls
   2. SQL access
      InterSystems iris provides SQL access to data through ObjectScript, rest API and JDBC
      Tools:
      https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=GSQL_smp
      Application:
      In the query business, the three-party system does not cooperate with the interface transformation, which leads to the difficulty of interface implementation. At this time, we use iris embedded model ObjectScript, rest API and JDBC to realize SQL access to data and establish business interface.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/SQL/BO/Query.cls
   3. Object access
      Through ObjectScript and rest API, InterSystems iris provides a way to store and change object instances in globals.
      File:
      https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=PAGE_multimodel_object
      Application:
      During the whole interaction process, the InterSystems iris object is manipulated directly. ObjectScript class definitions are often used as templates for creating objects such as patients, departments, or healthcare workers.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/MSG/Dept.cls
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/MSG/Doctor.cls

      https://github.com/ZBT-95/-IRIS-/blob/main/Application/MSG/SQLMessage.cls
   4. Rest API
      Application:
      Rest is an architectural style, not a well-defined format. It's resource oriented. Typically, resources are identified by URLs and explicitly use HTTP based methods such as get, post, put, and delete.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/Rest/Handler.cls
   5. BPL
      Business process is used to process message query model and corresponding SQL execution, and business message can be processed graphically.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/BP/QueryManage.cls
   6. JDBC
      The database is linked through JDBC to query business messages.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/SQL/BO/Query.cls
      
      
   7. Interoperability adapter
      Using SQL, soap and other inbound and outbound adapters to complete the application business message interaction.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/SOAP/BS/QueryService.cls
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/SQL/BO/Query.cls
   8. Workflow engine
      Use production to explain the business process in detail, and ensure the interaction of business messages.
      The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/PD/QueryProduction.cls
      
   9. Model
      There are self built model references in the program. For example: patient, health care, department model.
      *The application uses model linking
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/MSG/Dept.cls
      https://github.com/ZBT-95/-IRIS-/blob/main/Application/MSG/Doctor.cls
