The BS system comprises a browser, a server and a database, wherein the browser accesses data from the server, the server queries data from the database, the database returns results to the server, the server returns data from the browser, and a client can acquire relevant data according to the flow.
For CS systems, comprising a server and a client, the client accesses the server from the client, and the server returns the data results to the client.
The BS is therefore part of the hysteresis compared to the CS system, which is between ten thousand and 1 ten thousand model points, and since my application system response time is less than 500ms and any model total response time is less than 4s, the hysteresis time between BS and CS is calculated to be 300-500 model points, i.e. 2-3 accuracies.
Because the system of my application needs four parts of a left instrument, a right instrument, a middle map and a bottom three-dimensional part, the four parts are all H5 pages; therefore, only a single CS system is used, so that the repeatability is too high, the independence and individuation of the system are lacking, and the response speed of a BS system relative to the system is behind, so that the normal operation of the system and the operation of big data are not facilitated.
