我将采用文件系统方法。不需要创建或维护带有映像的DB，从长远来看，这将为您节省一些主要的麻烦。

数据数据库

文件的文件系统

我负责一些管理许多TB图像的应用程序。我们发现在数据库中存储文件路径是最好的。

这里有几个问题:

database storage is usually more expensive than file system storage you can super-accelerate file system access with standard off the shelf products for example, many web servers use the operating system's sendfile() system call to asynchronously send a file directly from the file system to the network interface. Images stored in a database don't benefit from this optimization. things like web servers, etc, need no special coding or processing to access images in the file system databases win out where transactional integrity between the image and metadata are important. it is more complex to manage integrity between db metadata and file system data it is difficult (within the context of a web application) to guarantee data has been flushed to disk on the filesystem

I have worked with many digital storage systems and they all store digital objects on the file system. They tend to use a branch approach, so there will be an archive tree on the file system, often starting with year of entry e.g. 2009, subdirectory will be month e.g. 8 for August, next directory will be day e.g. 11 and sometimes they will use hour as well, the file will then be named with the records persistent ID. Using BLOBS has its advantages and I have heard of it being used often in the IT parts of the chemical industry for storing thousands or millions of photographs and diagrams. It can provide more granular security, a single method of backup, potentially better data integrity and improved inter media searching, Oracle has many features for this within the package they used to call Intermedia (I think it is called something else now). The file system can also have granular security provided through a system such as XACML or another XML type security object. See D Space of Fedora Object Store for examples.

我将采用文件系统方法。正如其他一些人所指出的，大多数web服务器被构建为从文件路径发送图像。如果您不需要从数据库中写入或输出BLOB字段，那么您将获得更高的性能。当内容不变或希望限制数据库负载时，将图像存储在文件系统中可以更容易地设置静态页面。

通过网络将二进制数据从数据库中取出会导致巨大的延迟问题，并且伸缩性不好。

将路径存储在数据库中，让你的web服务器承担负载——这就是它的设计目的!
