Label:we need to consider the relationship between the data when we set up the database, in order to clarify the relationship between the data we need to do a uniform collation of the data. For the more complex database, we need to establish a database model, which can be divided into two steps: first, the structure analysis of the database and the use of tree, table and other descriptive data, and then analyze the database operation methods, rules and additions and deletions of the database ope

to integrate in a single icon, through the system monitoring, if the problem is found, the top left corner of the software shows a warning. The software can easily implement the route tracking, Ping and other commands through the topology diagram of Shanghai, and intuitively understand the overall network status.SmartDraw:Third, VisioGallery (called Shape Library) expansion1.

(notification circuit).5. There is an aggregation relationship between the re-insured notification and the Plan library. Because the plan library can be entered in advance, and the re-insurance notification is not necessarily linked, can exist independently. In the system is manually selected from the list. Delete the re-insurance notification without affecting the plan.6. There is an aggregation relationship between the cut notification and the demand order. Similarly, a demand order can exist

In the previous article "Automatic layout of telecommunication network topology Diagram", we introduced the knowledge of the automatic layout of HT for Web Telecommunication network topology diagram, but did not describe the usage of various automatic layouts in depth, and we will focus on the concrete implementation o

In the telecommunication network management system, the real-time display of the equipment status information is very important, usually mount a bunch of icons to display the status or alarm information, the limited information of the icons, sometimes need more detailed panels, even in the form of a chart, this article will combine the needs of recent customers, using the Qunee1.6 beta version, Realize real

Test instructionsTo a directed graph, ask him for the minimum spanning tree.Analysis:Directed graph of the fixed-point minimum spanning tree, also known as the minimum map, with the solution of the algorithm, the algorithm step-by detailed explanation: First determine if there is a minimum tree diagram, from the root node Dfs again. Root node, for all other vertex V, find a shortest edge with V

that the network is unreliable, You cannot guarantee that the last ACK message you send will be received by the other party, so the socket in the Last_ack state may be re-sending the fin message because the timeout does not receive an ACK message, so this time_wait state is used to resend the possible missing ACK message.Also openIt is possible for two applications to perform active open at the same time, although the likelihood of occurrence is low.

A very detailed layer-7 Reference Model diagram describes the relationship between each related protocol and each layer of protocol. For Beginners, this figure will give you a better understanding of the network-related TCP/IP protocol. 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/58/74/wKioL1Sx2XKjo44UAAR0j6lpBoU468.jpg "Title =" layer-7 Refer

sending, resulting in one more. What if a connection has been established, but the client suddenly fails? TCP also has a keepalive timer, obviously, if the client fails, the server can not continue to wait, wasted resources. The server resets the timer after each client request, usually set to 2 hours, and if two hours has not received any data from the client, the server sends a probe segment, which is sent every 75 minutes thereafter. If a 10 probe packet is still not

Microsoft Office SharePoint Server 2007 (MOSS 2007) is the core component of Microsoft 2007 Office system by building an Enterprise Portal and implementing powerful features such as teamwork, content management, workflow, business intelligence, and so on. The installation and deployment process for MOSS 2007 has many similarities to the early SPS 2003, but there are some differences, the process can be divided into the following phases: L Install the necessary Windows Components L Deploy AD envi

, we can deduce it on paper by ourselves. The following is a summary of the implementation process of the BP algorithm (directly misappropriation Ng's diagram bar):the above is the details of the BP algorithm principle. In summary, it is:1. Use forward propagation to calculate the "activation value" of each layer. 2. Calculate the residual of each output unit of the last layer, namely the output layer. 3, calculate the residual of the first node. 4, c
