BI? Or report?
Bi is something that is currently exhausted. The major users have finished the production system. They are struggling to engage in business analysis, decision-making support, the BI era is coming, each Bi manufacturer, you sing me, frequently launching my OLAP / DW products, make the industry not lively. For a time, the business is intelligent, and the beer is flying with the diaper.
How many BIs are there? In these prosperity, we see such a phenomenon: I don't have some goods true BI system, but most of the so-called business analysis systems, there are some reports, Can analyze the powerful BI tools for users to analyze the most basic report tools, and these things do not have a statement, it is still very difficult. Is it bi? Is it a report?
In fact, the multi-dimensional analysis is rarely applied in domestic projects. The spinning of the fancy is just the magic treasure of the BI manufacturer to impress the user. The multi-dimensional database of the background is seriously dependent on the business model. It is difficult to stabilize and practical. These big-name tools to the project are used as basic report tools.
This is actually a big BI manufacturer and its agents all know the things. However, these manufacturers have no one is willing to show that their products are used to do reports. It seems that only reports are too primitive, BI is not strong If you don't afford it, you should continue to marry users and play a "new installation of the emperor."
According to a foreign countries, the famous BI vendor is revealed, the comparison of the market share of real analytical applications and report applications in China is 1: 9, that is, most applications are enough. Most of the foreign BI tools are strong analytical capabilities, the ability to report is poor, but in this tempting big 9 does not grab, and the heart is willing to do that small 1, obviously does not meet the business interests; and put your own tools only Say the report tool, on the one hand, some fare, on the other hand, it is a self-violent, and the smart people can't do this stupid thing. Therefore, be sure to instill OLAP, multi-dimensional analysis, cubes, beer diapers, ..., a madness, is it in the future, let users pay for Bi, I am big enough, product look It is also spent, and the user does not understand anyway, it is very easy to make it.
Hey, dare to ask the world, who is more stupid!?
Is your B i?
OLAP is currently a hot BI method, but in fact, the success rate is not high, and users have spent a lot of money to analyze modeling design to purchase front-end tools, but the result is often not ideal. Let this B can I are really very difficult.
In fact, it is also very simple.
The implementation of OLAP needs to analyze the industry business, causing data cubes beforehand before you can do query analysis. For the failure to be expected, there is no corresponding cube available, OLAP is also impossible. For example, we asked a certain institution for three years of employees who have been rated as advanced workers in five consecutive years. In general, there must be this information in the general personnel database, but if there is no such data cube, use OLAP can't answer this personnel. The agency is easy to ask and have no problems, or require the technical department to edit a program or write a complex SQL to make.
In fact, the model principle of OLAP can only deal with the data that has been cified, that is, solves the problem of a single table query change problem, and most of the multi-table queries are difficult to deal with, how can a single table query? . OLAP, the most difficult multi-table change single work is transferred to modeling work, which requires people who have business experience to do, and the threshold is high efficiency, so this B is very difficult.
However, for domestic business, even if this is done, it is still not. China's political and economic rules are in constant changes, we can't move directly to the current model of the United States (then there are people to rebellious), and they can't stop. (Then my country must be "expeling the ball") It can only be reforms step by step. In this case, it is difficult to have a strict industry expert, which cannot predict the possible changes, and the model built is basically unstable, and it has changed again. The implementation of OLAP is seriously depends on the model model. In this way, use OLAP solutions, this B is simply impact I. In fact, it is the case, the business system is the same, the domestic application system often starts maintenance of patch from the day of the year, and then pushing back in two or three years, it is not the ability to develop business, it is not possible It is predicted that all the colleagues who have experienced project experience must have the same feeling. Unlike the United States, the business is relatively stable, and many industries have used systems written in COBOL language several decades ago. BI for the United States will inevitably defeat.
Poor B, when can I I?
