What is the significance of the WEB version of the reporting tool, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

If this web version of the report tool refers to the current self-help reports, that is, BI, multi-dimensional analysis, then it is meaningful, and various manufacturers have done a good job, allowing business staff to analyze all kinds of data through simple drag-and-drop to generate the reports they want.

Let's take a look at the current general functions of BI with an open source BI tool in the page section:

Drag and drop:

Drillthrough:

Slicing / data filtering:

As you can see, a multi-tier report with a certain complexity can be made on the WEB page.

However, if someone wants to expand the WEB tabulation function and let the business staff do all the reporting tasks on their own, it is impractical, and the tools designed according to this wish are meaningless. Because it is impossible for business staff to handle Chinese-style complex reports.

The development of complex report involves a variety of data relations, data sources, parameters and expressions, which requires programmers with sufficient abstract ability to understand and imagine how the report template is transformed into the final presentation report. Business people can't do it either in desktop designers or WEB designers, and they don't want to do it. The task of making tables still has to be done by technicians, and few technicians want to use these WEB-side tabulation tools. Because of the technical limitations of the designer on the WEB side, it is difficult to be as fully functional as the desktop designer, many complex functions can not be done, and the development efficiency is inefficient. For projects with many reports, efficiency is the cost.

Therefore, report tools must provide desktop designers, and all excellent domestic manufacturers basically make reports through desktop designers. In fact, you think about whether there are any mature development tools for programmers that are based on WEB, complex report development is essentially a development tool.

However, the WEB version of the report tool has many disadvantages when faced with the development of complex reports:

1. The designer on the WEB side will make the application bloated and complicated. The application of the original report is basically only more than 100m in size, but with the WEB designer, it may reach more than 500m and the maintenance workload is heavy.

2. If the application is too large, it will inevitably affect the stability. In general, there will be a lot of bug and changes in web designers. Each change will update the server and restart it.

3. The function and running efficiency of JS in the browser is much worse than that of the client program, the complex and convenient functions are difficult to develop (such as online debugging, expression execution, etc.), the barely developed ones are not smooth, and the user experience is poor.

4. All the operations of the WEB tabulation tool are completed in the browser, and the dependence on the browser and the network is extremely high. When the browser does not support it, or the network is not smooth, it will greatly affect the development efficiency.

An important advantage of WEB applications is that they can be developed remotely, but it is possible to use a desktop designer to connect to a remote server.

For example:

After the IDE side connects to the server remotely, you can upload and maintain the report file:
