Some misunderstandings of the Chinese

There is always some wrong ideas in China's regularity or use of related products. Since the so-called hipster look at the doorway, the unhealthy trend of the country seems to have pointed out. The less speed is, the faster the speed, the completion is zero, God forgive these people. In fact, anything has its opposite, if we have to do a simple calculation of 1 1 nature, then you may be some. But I hope that you will understand that a memory is fast, and it is hard to break by Daxing. This is to say, if possible, put some data select to memory, and then processed further according to your needs, usually a 4-minute huge analysis, can shorten within a minute, and all this is just more data SELECT Yes. When a huge analysis involves numerous data, many people will choose to make an index. I have seen more than some of the designer's excellent design, they always proudly run fast, day! I don't know if you understand the speed relationship and write speed of your hard drive. In general, the outer speed is higher than the inner road, and the computer always writes the data to the outer channel and then writes the rely on the sector. From the storage location, there is no advantage of establishing too much waste. From a database design perspective, someone designed to design this database is just the main people who are temporarily hugged. I have never seen any large-scale database to use the index of the stack to improve the speed, the database needs to be used, and you can use the index. So how many queries and database are not directly related, just the game on text. The better the fast database is better - all the needs of the day, is this?! Anyone wants to get what they need in the shortest time, this is human nature. I am a person belonging to such an acute child. However, the database is not a play, it is not a handbroof cabinet. We choose a database to manage our information. Nature is to hope to bring our interests. Do you realize that the source of this benefit is the data? What if the database is lost? I can't imagine myself. If you are slow, then I will take a few examples. Be a forum, hard work slowly operates a forum, but suddenly I suddenly find the inexplicable thing in the database, the user is lost, the post is gone, the database collapses, what should you? Be a business website, while users send 1,000 yuan orders, the database is upset. . What is this? People have feelings with the machine compared to the machine. When we choose a product as our database, you must pay attention to this itself has perfect crash recovery capabilities, and itself has real-time backup or you can buy database software for third-party similar products. If there is no, it has not been developed, but it is always useful as a commercial database before no proper or folded program. Don't deliberately care about the cost of each CPU, restraint your desire, and reason for reason. Don't bind your wrist to eat evil. The more you save money, the better - don't too much, there is an old saying that everyone is worthy of money, the bird is dead. When you want to save costs, the other party wants to save your own labor. Any institution has its own interest center, both business or public welfare, each of which will encourage their own interests to maximize. If you can't give you sesame, you will lose gold, and the data is not a thing to play. If you lose it, you can't make it. In any case, remember to spend money to buy a technical support for business nature. If some database itself does not, I want to find a consulting company for this job. Telling money means a responsibility, this responsibility is related to their respective benefits. It is a very wonderful thing when you encounter problems, and this is more cost-effective than special employees. Don't make a small money, you should understand that the need to develop financial resources will never have a solution for one for all. The name is big, the ear is hard, you can try it in some forums to get product promotion.

Of course, please don't make it clear about your application and planning, it is not a commercial confidential, everything is very subtle. You will get a lot of answers, but harvest is not very big, often can't. The promotion of the product and the recommended products will have something to doped inside. Such as money, self-esteem, etc., many choices are all about very subtle things. Understand what you need, objective evaluation companies currently and in the next year, it is difficult to say that it is difficult to say that the commercial warfare and clouds can make it difficult to say that it is difficult to invest a large number of funds at the same time, which will inevitably affect funds at the same time. turnover. After all, there is a business model called software upgrade waiting for you to develop. I think about when I wrote this thing, I frankly my emotions a bit fluctuated. However, please believe that what I know is not empty. I think the database should be a safe storage of data and effective organizing data resources, and can quickly provide data analysis software when I need to use data resources. Thus he should at least with the following advanced features: custom functions, custom results analysis, line lock, data log, real-time backup (hot spare). If a database does not have some advanced features mentioned above, then the enterprise level app is only available peripheral, and it will bring a loss that cannot be predicted slightly. Don't be too much noun, the benefits come from a savvy and savvy source from reason. The little is not met, but also hopes a middle master. Blogs: mysql.blogbus.com
