Search MIS results in 9CBS Blog: 2 A successful information management system, "Thought is the soul, technology is key". -------------------------------------------------- - We should be programmed to solve the problem, not for programming! ---------------------------------------------- Most of the time, and it is very important ------------------------------------------------------------------------------------------------------------------- - In terms of programming technology, there is still a very profound. Sometimes when checking or modifying certain functional modules, although it is a code, it can be separated from a period of time, it is a cloud that I don't know the code, I don't have it. A little temper, I only blame my comment at the beginning. After ate so much loss, I spent a lot of time, I finally forced my own habit of writing a comment, now if some function module code, now if some The code of the function module has a drawback, which can be revised quickly according to the annotation. Of course, in addition to writing a comment, the writing format should be specified, the program code is simple and important, -------------------------- -------------------------------------------------- ------------------ To consider the calculation level of the code, the lengthy code implementation, many of which can be replaced by more efficient code, don't say you have worked hard The constructed C / S structure was originally to reduce the processing of the client, who once thought of being tired of the code that you were writing, uncomfortable. -------------------------------------------------- ------ Development MIS is a system engineering, regardless of the analysis of the previous period, the medium-term programming is good, the late implementation is also good, always have a unity and cooperation, and only the factors are taken into it. Unremitting efforts can be successful! "

-------------------------------------------------- --------------------------] Handling the communication between people and people, there must be everything you have to see, then you will see How to face, then how to reach consensus, rationality, scientific thinking to think and solve problems, clarify their own point of view, explain the feasibility and versatility of their own ideas, directly illustrate the discussion of the idea to open the public to make the system as much as possible = ============================================================================================================================================================================================================= =========

Some think about data structure

Simple data structure is a computer discipline for studying data logic structure and physical structure! 1. What is good? Ok, what is it? Linear table (what is the advantage, what shortcoming? ...) Data structure knowledge tells you! 2. Since there is a shortcomings in the array, it will be used with a list (why not to increase the data, delete, changed to see its physical implementation, it is stored on a discontinuous physical memory, so ... [reason is obvious] ) {Actual application, if your program is designed to design a large amount of data, delete, change, you should consider using the list! ! ! ! } ----------------> Think more I want to keep in mind that the computer's application is to solve practical problems), ok! Take a look at the real world (queuing problem, filling problems ....) Simple linked list is not solved, what should I do? Modify, enhance the chain function --------> Stack, the queue has appeared, naturally solving the problem is simple, and it is efficient! 4. There is a good advantage of linear menu and linked list, why can't it be used in conjunction? This question is mentioned in the <:)> Database? What is the database? (Simple, it is a collection of files) Relational database is a two-dimensional table. If your needs are just an increase, delete, change the number of records with a property, and its properties will never change! How to do? This requires the joint use of the two, the property is used, and the recording list (: If this demand is very big in real life, you can design your dbms :) 5. Talk again, talk, queue, their Applications If you learn hardware or compare the computer operation, then you know the importance of these! Interrupt operation, call in the program, is there no stack this data structure line? ? ? ? Is there a FIFO in various management algorithms? It seems that there is almost every management. It can be seen that the queue has this data structure ... 6. Tree, havehtable ........ The advantage is too much, the application is of course more! XML know? He is a tree structure, then why didn't you apply him in practice? ? ? ? ? Inheritance relationship in real life is so many (your family, government agency ...) requires tree access! Hashtable is good.

You can quickly find it through Key! In real life, is your name not equivalent to Key? Don't you know why the ancients want to name yourself? (Think about it) A good idea mapping in HashTable, ........... .................// waiting for you to send ......... .......// waiting for you to send ................./ ============================================================================================================================================================================================================= First-class company sells standards, second-class companies selling technology, and three streams sell products. Software companies that can be used in the Chinese market do not seem to be much, and most software companies currently use the project as the company's survival and development, this is related to the specialization of the Chinese market, but also It is because of these special things make us yet laid, just like welcome to use pirated software. Therefore, the success or failure of the project determines whether the company can survive and develop, especially software companies that have not introduced third-party funds. The success of the project has a lot of factors, including demand research analysis, project manager hosting the ability, teamwork coordination, customer cooperation, etc. Get the best cost effectiveness. The personnel of the project manager are the key to success or failure in the actual operation of the project.

A MIS project manager is the key to success or failure. .
