As a website optimization officer, We are very aware of the importance of Robots.txt files on our site, Robots.txt file is just a plain text file, it is like a site map, to the search engine to identify the road, when spiders search a site, it first crawl to check the root directory of the site exists Robots.txt files, if there is, Search engines will follow the contents of the file to determine the scope of access, if the file does not exist, then the search engine will follow the link to crawl

Benefits of using frameworks 1) Improve development efficiency: including development and maintenance 2) Change in requirements: Reduce the amount of changes 3) Decoupling architecture Hibernate cache First-level cache (session cache and Sessionfactory's built-in cache), level two cache (sessionfactory external cache). The built-in cache contains mapping metadata and predefined SQL statements, which are read-only, and external caches, whos

time of establishment. When an object is established, it is sufficient to calculate their size according to the application, then define the values of objects initial, next and minextents based on the data, so that the database can achieve a good balance between physical storage and dynamic growth times, so that these objects do not grow frequently. Also does not occupy the database too much. 　　Conclusion Optimizing the Oracle database is very important to improve the usability and efficiency o

Topic Background: Solution One: #include Solution Two: #include Results Analysis: With this simple example, we can see the benefits of using an array to store the computational process: 1: Code Simplicity 2: High efficiency, as long as the calculation once, then all the results are put in the inside, only need to go to the corresponding location to fetch the data. 3: Simple logic, clear thinking

See: http://blog.yemou.net/article/query/info/tytfjhfascvhzxcyt338Many tables contain nullable (NULL) columns, even if the application well does not need to save NULL, because nullable is the default property of the column. It is generally preferable to specify column NOT NULL unless you really need to store a null value.If the query contains nullable columns, it is more difficult for MySQL to optimize because nullable columns make indexing, index statistics, and value comparisons more complex.

as employee work number, employee name, employee position, and so on in the employee table. This is equivalent to in the employee relationship, the projection operation, that is, the selection of employee work number, employee name, employee position 3 attributes, forming a new relationship, 1 shows.Figure 1 Using projection operations to get a view of ordinary users Vw_employeesSimilarly, for advanced users, you can create a view named Vw_employees_hr, which selects all the columns in the Empl

MySQL databases support single-item and asynchronous replication. During the replication process, one server acts as the master server, and the other server acts as the slave server. I have gained some benefits through the MySQL replication function and will share it with you later. MySQL databases support single-item and asynchronous replication. During the replication process, one server acts as the master server, and the other server acts as the sl

higher ripple voltage (the ideal output DC voltage should be a horizontal line, and the ripple voltage is the crest and trough of the horizon), so that the engineer in the design, To use the smallest ESR capacitor.The relationship between the ESR value and the ripple voltage can be expressed in equation V=r (ESR) XI. The V in this formula represents the ripple voltage, and R indicates that the esr,i of the capacitor represents the current. Higher ESR capacitors, as internal heat becomes more se

Original: SQL Server Tour--first stop the system view that brings us benefits　　Originally wanted to write something about this series, and then think of everyone as a programmer, the most used is the database, but in fact a lot like me to work in the first line of the code farm, on the SQLAll smattering, don't talk about optimization and the database of the bottom of the understanding, I also like this ...One: those system views1.

With the development of China's routing industry and the wide application of L3 router switches, I have studied the benefits of choosing a l3 router switch. I will share with you here, I hope it will be useful to you. In addition to excellent performance, layer-3 route switches also have some features that traditional layer-2 switches do not have. These features can bring many benefits to the Construction o

Layer-3 switches are quite common, so I have studied the comprehensive analysis of the benefits of using layer-3 switches. Here I will share with you, hoping to help you. Layer-2 switches are based on mac addresses, frame layer-3 switches are based on IP addresses, and data forwarding (packet) is similar to a router. However, because ASIC is used, the speed is generally faster! To describe the role of a layer-3 Switch in many network devices, it is no

As cloud computing gradually becomes the trend of future development, many plausible ideas are becoming increasingly prominent, and security concerns are emerging. This article focuses on the seven potential benefits of cloud computing for security technology. I. centralized data storage Reduce Data leaks: This is the most talked about by cloud service providers. Before the emergence of cloud computing, data is often easily leaked, especially the thef

1, what is the event delegate: colloquially speaking, the event is onclick,onmouseover,onmouseout, and so is the event, commissioned, is to let others do, this event was added to some elements, but you add to others to do, Complete this event. That is: using the principle of bubbling, the event is added to the parent, triggering the execution effect. Benefits: 1, improve performance. We can look at one example: Each Li needs to be triggered to chan

MySQL databases support single-item and asynchronous replication. During the replication process, one server acts as the master server, and the other server acts as the slave server. As shown in. The master server writes the update information to a specific binary file. An index of the file is maintained to track log loops. This log can be recorded and sent to the slave server for updates. When an slave server is connected to the master server, the slave server will notify the master server to r
