I: Internet thinking is a layer of paper
(1) the Internet is a creator of value, but it is first of all a destroyer of value. It is destroying many traditional business models. Whoever is closest to the Internet, the Internet will destroy first
(2) big companies don't fail because they are stupid. In fact, they have a lot of smart people, often because they are arrogant. Big companies don't understand new models, so they laugh at new things with their old experience; But even if they understand the new model, they also miss the opportunity of transformation because they are not willing to give up their existing business income, which gives small companies enough time and space for development<
2: the core is proct experience
the way of proct is similar. As long as you are a consumer proct, directly facing consumers, and make the proct simple and easy to use, users will like it. Whether it is virtual Internet services, or real-world services, or physical procts, there are a lot of opportunities to improve the user experience. And once you start to improve the user experience, that means the beginning of innovation
Three: business model is not a money making model
(1) the basis of business model is users. Without users, any business model is a floating cloud. They don't know that the core of a business model is procts, and the essence is to create value for users through procts. The business model also includes finding the most demanding user groups, contacting these users with smart promotion methods, and constantly polishing the procts in the process of contacting. When you have a huge user base, you will be able to make money
(2) what is a business model? In fact, the business model is not a money making model. It includes at least four aspects: proct model, user model, promotion model, and finally the revenue model, that is, how to make money. The real promotion mode should design corresponding promotion methods according to your user groups and procts<
Four: it's the user, not the customer
in my opinion, the definition of the user is the person who you can provide a kind of service for a long time, who can let him perceive your existence for a long time, and who can keep in touch with you for a long time. Only when you have accumulated enough users on the Internet can you be able to turn some of them into your customers< (1) don't expect a certain version to bring revolution, but rely on many small versions to realize revolution. That is to say, it is not to plan a huge technical system at the beginning, but to start from one point, or even to make some rudimentary prototypes or rough first versions. The most important thing is to release and win over users as soon as possible, and then make adjustments after being verified and instructed by the market. Don't be afraid to redo the proct sometimes or improve it in the future
(2) in the aspect of technology development, we adopt the idea of fast running, step by step, trial and error constantly, and set small wins as big ones. With little progress, we surpass big companies< There are three forms of innovation: (1) it is difficult to happen, that is, invention 2) One is to innovate from the business model, that is to make the expensive things cheap and the charged ones free 3) One is to innovate from experience, that is, to simplify the complex and difficult things and to make the bulky things portable
Why are free business models and user experience innovations subversive? Because it is in line with the needs of human nature to make the expensive cheap and the charged free. It is also in line with the needs of human nature to make the complex simple and the bulky portable< How does 360 subvert the traditional anti-virus market
reflection includes two aspects: first, what experiences can be summed up from past failures to avoid repeating them; Second, keep learning attitude, learn from users and competitors< In his opinion, innovation is the innovation of proction technology and the change of proction methods, which plays a supreme role in the economic development of modern capitalism. His "disruptive innovation" is to introce a new combination of proction factors and proction conditions into the proction system
destruction and subversion both emphasize breaking the original balance and establishing a new order<
nine: the power of subversion comes from the flank and focus
the power of subversion never comes from the mainstream and popular market, but from the edge and flank
subversion needs micro force, not platform force. Platform style can not proce subversive power. The reason why big companies can become platforms is that they expand the scale in the process of solving users' problems and naturally become a platform. For us entrepreneurs who have no resources and are hard pressed, the real subversive power comes from the micro place, from the flank, from the edge, from focusing resources on one point to pursue the ultimate. Whether it's easy or cheap, the most important thing is the ultimate.
the data types in Oracle include character type, number type, date type, etc. . Specific introction is as follows:
character type:
char (n): used to identify fixed length string
when the actual data is insufficient to define the length, the space is used to complete the insufficient bits on the right. Varchar (n): variable string type
is the data type that the database must implement according to the SQL standard. You can store empty strings
VARCHAR2 (n): variable string type is a variable length string type defined by Oracle on the basis of varchar. When used as a column type, the maximum length can be defined as 4000; When used as a variable type, the length can be defined as 32767. An empty string cannot be stored
extended data:
data element is generally composed of object class, feature and representation:
(1) object class. It is a collection of things in the real world or abstract concept, with clear boundary and meaning, and its characteristics and behavior follow the same rules and can be identified
(2) property. It is a property shared by all indivials of the object class, and it is the basis for the object to be different from other members
(3) represents representation. It is a combination of value field, data type and expression mode, and it also includes unit of measurement, character set and other information when necessary
object class is the entity that we want to study, collect and store relevant data, such as personnel, facilities, equipment, organization, environment, materials, etc. Characteristics are a means used by people to distinguish and identify things, such as the name, gender, height, weight, position of personnel, tank model, caliber, height, length, effective range, etc
Therepresentation is a description of how data elements are expressed. Any change in any part of the various components of the representation will proce different representations. For example, the use of "cm" or "m" as the unit of measurement for a person's height is two different representations of the height characteristics of a person
