The REST service can help developers to provide services to end users with a simple and unified interface. However, in the application scenario of data analysis, some mature data analysis tools (such as Tableau, Excel, etc.) require the user to provide an ODBC data source, in which case the REST service does not meet the user's need for data usage. This article provides a detailed overview of how to develop a custom ODBC driver based on the existing rest service from an implementation perspective. The article focuses on the introduction of ODBC ...

In the past Client-server, RPC framework hierarchies such as CORBA and RMI did not seek because such technologies could extend a stand-alone IPC (inter-process communication, interprocess communication) to communication between multiple computers, This is very helpful for extensibility, but for a variety of reasons these RPC frameworks have not been adopted by the industry on a large scale. In the era of cloud computing, more and more machines are needed for distributed communications, although they can be easily communicated by using the HTTP protocol.
