What is the essential difference between Bi development and report development?

I saw a problem on the Internet not long ago , business intelligence BI What is the essential difference between report development , Find it interesting , Take it out and discuss it with you . In fact, today's business intelligence BI The boundary with the report becomes more and more blurred , Can do visual analysis and display , Can also achieve Chinese style two-dimensional report , Basically, there is little difference in the front-end presentation ability . Of course , There are still some people using the thinking of statements to do business intelligence BI, Such an approach cannot respond to the growing demand for business analysis in the future . Let me talk about the essential difference between them .

business intelligence BI Development and report development The essence difference

business intelligence BI The essential difference between development and report development is that report is user oriented report development , What report requirements do users need , Just write SQL Data retrieval forms a data set to support the front-end report presentation . And business intelligence BI Model oriented development , By constructing a reasonable analysis model , Can support to N Many visual analysis shows .

business intelligence BI Development and report development , These two methods may be basically the same in the final presentation effect to users , But the difference lies in the scalability of the analysis page and the scalability of the model , What is actually considered behind this is the underlying data architecture 、 The design of data warehouse architecture .

Report development and business intelligence BI Development has a very big difference , Business analysis itself is easy to be ignored in the design and development of most reports , Report driven . When users propose new adjustments on the report 、 Adjustment of business calculation caliber 、 Adjustment of analysis dimension , Basically, relevant data sets need to be readjusted . And there will be repeated calculation of indicators 、 Repeat quotation 、 Recalculation of dimensions , There is not even a unified consistency dimension . This leads to changes in business requirements , There will be a lot of repetitive work .

And in business intelligence BI The project is under construction , The final visual display effect will not be considered at all in the early stage , Focus on what the first user needs to analyze , Second, from what point of view . business intelligence BI In the project , What analysis refers to is the analysis index , The analysis from what angle is the dimension , Analysis indicators and dimensions can form a complete analysis model . As for how users will analyze in the future , In fact, the corresponding dimensions and indicators can be found from the mature analysis model .

Some friends will also ask , If business intelligence BI Some indicators in the project have not been considered by users before , Not in the analytical model , The attributes of some dimensions need not be added in the future , This kind of analysis model is not stable .

actually , There is no 100% perfect analysis model , The analysis model will also expand and change with the expansion of user business analysis requirements , What matters is a reasonable business intelligence BI The analysis model will be less affected by this , A little quick adjustment can support N Multiple analysis , And the previous analysis results can also be unaffected to the greatest extent . In business intelligence BI There is a complete set of modeling methodology to support , The core is data warehouse modeling 、 Dimensional modeling 、 Consistency dimension and other concepts .

General report development process , Including some business intelligence BI The development process , Write at the beginning SQL Count , Form a wide table to present the page . If the user doesn't want these effects , We need to organize again SQL Fetching script , This basically focuses on the process of data retrieval , Without really paying attention to what users want , What may be analyzed later .

So in our business intelligence BI Under construction , We won't do any data retrieval at the beginning , Instead, we should fully communicate with users' needs to build a reasonable 、 Robust analysis model , Confirm the final visualization effect through prototype design and users , After there is no problem, we can develop data retrieval . This is actually Kimball From prototype to model in methodology , Development methodology from model to data . As long as we master the methodology and integrate , You can flexibly respond to various business growth needs .
