With the advent of the Internet era, various Internet-based application systems emerge one after another. Most application systems use image data and need to display images on the user interface. This section describes how to store images in a folder and display them as required. The specific implementation step is to store the additional information of the image path and other records in the database, while the real image file is stored in a folder. This method is a good solution
, it is found that the price of such servers is not low (for some companies, such a price does not matter, it is impossible to use such a small NAS storage service, but for small companies, the cost is still very important ), A good friend has a PC host that is idle and not used. The machine is normal, but the design and processing capabilities cannot be kept up, so he decided to use it, find another NAS server
After learning how and how the Exchange Server store works, let's look at some management tips for the messaging storage System. After mastering the principle of the administrator will have a deeper understanding of these skills, in the actual work to be confident and comfortable.

Recently, the company's file server storage space frequently alarm, such an important server in case of space is full of server can not access or downtime, then we do it will lose the job, but because the file server is the daily need to use, we also not good whole stop what
Summary: SQL Server Compact Edition (SSCE) provides a powerful and lightweight data storage engine for building multiple application types. This article describes data storage issues for client applications and small-scale server applications. This article discusses the feature set of SSCE and how the feature set solve

Brief introduction
The column storage index already exists in SQL Server 2012, but only nonclustered column indexes are allowed in SQL Server 2012, which means that the column index refers to the underlying data on the original row storage index, and therefore consumes more storag
What am I going to do?
Change the listener address of the ASE. For me with obsessive-compulsive disorder, the ASE listens by default to 127.0.0.1:10000-10002, which makes me unacceptable, so I'm going to change it to a domain + 80 port;
Put in the container, ASE only allow single instance to run, for this thing, I want to open three virtual machines in three environments?
Connect to SQL Server, not SQL
The virtualized server environment brings great challenges to storage managers. At least we need to monitor the connection between data storage and virtual servers. Storage Management products available in this new environment can be used on the market, allowing users to continuously monitor applications running on vir

However, privileged users who can access system tables through the DAC port or who can directly access data files can use this text. In addition, users who can append a debugger to server processes can retrieve decrypted processes from the memory at runtime. For more information about accessing system

Accidentally saw a friend wrote an article "The Table data batch generation INSERT statement implementation of the stored procedure." I look at the text of the two storage code, I feel that two are not satisfied, are generated by the single mode of insertion, the data row slightly larger performance will be affected. A similar implementation of a second version exists in the company, but it is based on multiline mode, or it needs to be manually added
