Oracle Optimization-double-edged sword and oracle optimization double-edged sword Oracle optimization is a double-edged sword. Pay special attention to the use of this sword:OLTP or OLAP Optimization 1: Index During DML operations

Inheritance is a double-edged sword.Through the previous sections, we should have a better understanding of inheritance, but before we say that inheritance is actually a double-edged sword, why do you say so? On the one hand, inheritance is very powerful, on the other hand because of the destructive power of inheritanc

, extensibility? How to combine it with the struct, the class tightly, achieves the final double-edged sword action?Solution:This is also the problem I encountered when learning abstract classes and interfaces, from the three questions I summed up, it is not difficult to see that this is perhaps the three stages that most of our programmers are experiencing problems,The first stage (basic concept): Just lik

opinion, the acquisition of mojang is definitely a double-edged sword for Microsoft. USD 2.5 billion! Microsoft has invested heavily in the acquisition of popular game manufacturers To be honest, the $2.5 billion acquisition of mojang is not much more than Microsoft's $7.2 billion acquisition of Nokia, Facebook's $ more than 19 billion acquisition of WhatsApp, and Apple's $3.2 billion acquisition of beats.

Question: Code optimization double-edged sword, An error occurs accidentally. Static in GCC, Difficult to detect after an error, If you don't want to cover the road, Volatile! Laboratory development of the sensor network node using the AVR series microcontroller circuit board, AVR-GCC provides 5-level code optimization, because the node Running code is more complex, the functions such as routing, networkin

Everything in the world is relative, and there are pros and cons. Corporate culture is the soul of the enterprise, at the same time the corporate culture is a double-edged sword. Excellent corporate culture not only makes enterprises invincible in the market competition. The shoddy corporate culture, however, will sooner or later allow companies to taste the bitter fruit of their own brewing.In the Northern

if you forget your code for a while, you cannot understand your code. unit test code helps you understand the functions and requirements of the Code. 4. There is a relatively high possibility of demand change in the future. After the demand changes, you don't have to worry too much about whether the written code is correct or not and whether the existing code logic is damaged. 4. unit testing should also focus on quality and do not write useless unit test code. It is better to write unit

service, the game quality will be more critical. This requires small and medium-sized hand-tour enterprise boutique games and fine-grained operations, hand-travel and intermodal transport platform may also be riding this wave of the tide set sail.With the continuous promotion of the market competition, the precision marketing mode has become the main direction of the future development. The development, promotion and marketing of the hand-travel intermodal platform are based on the game and the

-business industry is a double-edged sword? Any search for a product from a business-to-business site copy the description to Baidu to see, basically repeat the number at least 100 above, so large repeatability, the content is not quality characteristics, we all know too many repetitive pages, for the low weight of the site is simply a disaster, no quality content injection, Want to let the site accumulate

Oracle Optimization-double-edged sword Oracle optimization is a double-edged sword. Pay special attention to the use of this sword:OLTP or OLAP Optimization 1: Index During DML operations, indexes must be maintained. If a large number of DML operations are performed, check whether I/O is too old? Index advantages:

The problem arises:When we use the abstract classes and interfaces of C #, we often encounter the following similar problems, broadly summarized as follows:(1) What are the essential differences and connections between abstract classes and interfaces?(2) When to choose the use of abstract classes, then when to use the interface is most appropriate?(3) How to use the project in order to make the project more maintainable, extensibility? How to combine it with the struct, the class tightly, achiev

inspection. For code behavior, you can either use Coverity's tall business software, or PYSONAR2, or use AST to write a simple check code.Third: Unit TestingThe importance of unit testing presumably everyone knows that in Python there are official doctest, unittest, and many more powerful frameworks, such as nose, mock.IV: 100% coverage testFor the dynamic language of Python, there is little execution code, and there is almost no better way to check the code errors, so coverage testing is very

service, the game quality will be more critical.

A double-edged sword for the frequent use of JSON Recently, I got a chat room and used JSON as the intermediate storage medium to implement the chat room function on a single page. The advantage of JSON is that it is easy to parse and the JSON string can be placed in the memory, this reduces I/O operations and makes parsing JavaScript very convenient, reducing the process of language parsing. the JS framewo

With the search engine on the SEO concern, site optimization by more and more people agree. But SEO is a double-edged sword, use properly can quickly improve the site rankings, development prospects are flourishing. But the use of improper not only webmaster a painstaking effort, even the site may be affected by the loss of power is not worth it. However, although the risk is big, after weighing the pros an
