Tracking vaccinations around the world with IRIS

The pandemic that struck the world in 2020 made everyone follow the news and the numbers that involve the COVID-19.

Why don’t you take that opportunity to create something simple and pleasant, to follow the number of vaccinations worldwide?

To face this challenge, I'm using the data provided by Our World in Data - Research and data to make progress against the world’s largest problems.

They have a dedicated repository on Github with the data of COVID-19, and I took the vaccination data to help me with my tracker.

跨命名空间开发

编码中,zn “命名空间”这样跨命名空间使用操作会导致队列中具有很多 _sync:进程号,不知道这种情况是切换命名空间操作的问题还是使用的问题?对于这种跨命名空间有没有更好的应用方式? In coding, the operation of Zn "namespace" across the namespace will lead to a lot of errors in the queue_ Sync: process number. I don't know if this is a problem of switching the namespace operation or using it? Is there a better way to apply this kind of cross namespace?

Built in multi model integration using InterSystems iris data platform

Built in multi model integration using InterSystems iris data platform

Solution of hospital information inquiry business

Integration of hospital information query business solutions using InterSystems IRIS data platform with built-in multiple models

### 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 use InterSystems IRIS data platform built-in multi model integration of hospital information query business solutions. 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

### Application model and Application Introduction:

1. Using the model   
    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...   
    **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.   
    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=GS...   
    **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.   
    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=PA...   
    **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.   
2. Establish application cases (this application takes patients as an example)   
    1. application construction:   
        1. basic environment   
        Iris version information: iris for windows (x86-64) 2020.1 (build 215u) mon Mar 30 2020 20:14:33 EDT \[Health Connect:2.1.0]   
        Iris has java and JDBC environment   
        Postman can be used for testing   
        2. installation steps   
        ① Establish rest Service   
        New web application → configure dispatch class → configure permission.   
        This step can be seen in the following pictures: application running / webreplication (query). PNG and webreplication (role). PNG   
        ② Configure sql-jdbc   
        Establish SQL connection, connect to test database mysql, import test jhip_ patient_ info.sql   
        ③ Configuration lookup table   
        Global-^ Ens.LookupTable Look up table file import in   
        ④ Import code   
        Import the code in applicationcode, compile and open production,   
        Note: modify Bo configuration information (DNS), configure Java gateway, etc   
    2. application process   
    Omitted (see PDF)   
    3. Application Test   
    The postman tool (or other tools) can be used for test verification   
    Postman can import Query.postman_ collection.json , change IP, port number information and URL for testing.   
    4. application summary   
    This application takes patient service query as a case, which can be configured with inbound and outbound protocols, query conditions and business types to solve the problem of query business interface.   

Finally, if you agree with this solution, please vote for the application in the inter systems multi model database contest.
