Baidu statistics: free professional website traffic analysis tools http://tongji.baidu.com/web/welcome/login Solve the Problem of page access statistics If you need a report, how does the report data be generated? The current query is impossible. What is the mechanism? Huang's answer is: create another database, preferably on a machine different from the production database, and then design a database table for each report. The data in the table comes from the ETL Data Extraction Tool, the

1. Introduction Pentaho Report Designer is a WYSIWYG open-source Report design tool. When designing a report, you can drag and drop various report controls at will, and quickly and conveniently set the report data source. You can preview the report results at any time during the report design process. Is a good report design tool. 2. Technical FeaturesThe following briefly lists some of the main technical features of

A few days ago to see brother sent a picture in the group to explain the synchronous blocking, asynchronous blocking, synchronous non-blocking, asynchronous non-blocking, as follows: Weekend Nothing, the code implemented a bit. It's mostly asynchronous, non-blocking, with callbacks. The so-called callback: the Class A called a method in Class C, and then the Class B in turn calls the method in class D,d This method is called the callback method, the way is implemented as follows: Class

Scale generation: mainly related to water quality. If the water quality is hard, the oxygen content in the water is insufficient, and the water molecules are unstable, the solubility of calcium and magnesium ions in the water will decrease, and precipitation will increase, thus forming scale. As long as the water temperature exceeds 60 ℃, especially in the north where the water quality is hard, there will certainly be scale, and there will be scale in the daily

, you can play it on your own. Of course, you also need to check whether the boss has returned the result in a few minutes. Blocking and non-blocking are irrelevant to synchronous Asynchronization. It has nothing to do with how the boss answers your results. Attach anotherEasy to understand examples: Old Zhang loves drinking tea, without talking nonsense, and boiling water.

the process of processing a request for payment, which also led to the receipt of the result of a notification to xiaoming, or after the additional notice. Another example of Lao Zhang Love tea, nonsense do not say, boiled water.

ETL (extract-transform-load abbreviation, that is, data extraction, transformation, loading process), for enterprise or industry applications, we often encounter a variety of data processing, conversion, migration, so understand and master the use of an ETL tool, essential, Here I introduce a I used in the work of 3 years of ETL tools kettle, the spirit of good things not only enjoy the idea of sharing the collision with everyone to exchange a bit! In

caller does not immediately get the result. Instead, the caller notifies the caller through state, notification, or through a callback function after the call is made. Typical asynchronous programming models such as Node.js. 2016.4.17 Update: POSIX defines the two terms: Synchronous I/O operations: Causes the request process to block until I/O operation completes asynchronous I/O operations: does not cause the request process to block 2. Blocking and Non-blocking Blocking and non-blockin

Overview I/O types: Synchronous and Asynchronous: synchronous, asyncrhonousthe focus is on the message notification mechanismSynchronization: The call does not return immediately, but once returned, the final result can be returned;Asynchronous: After the call is issued, the callee returns the message immediately, but returns the non-final result; The callee notifies the caller through the state, notification mechanism, or the callback function to process the result;Blocking and non-blocking: bl

This time to write the NIO implementation of non-blocking communication encountered a lot of problems, I understand the non-blocking is for a user's read and write does not restrict each other, and in this writing process, it is found that non-blocking is relative to many users.See on-Line a synchronous asynchronous blocking non-blocking example, feel very good, and then copied over:Lao Zhang Love tea, nonsense do not say, boiled water.

Old Zhang loves drinking tea, without talking nonsense, and boiling water. Appearance character: Lao Zhang, two kettle (ordinary kettle for short; ring kettle for short ). 1. Old Zhang put the kettle on the fire and waited for the water to open. (Synchronous blocking) Lao Zhang thinks he is a bit silly. 2. Old Zhang pu
