in each page are also maintained through a doubly linked list, which can be stored on the physical storage as well as in the primary key.Another benefit of a clustered index is that it has a very fast sort lookup and range lookup for primary keys.Secondary index (nonclustered index):The leaf node does not contain all the data for the row record.In addition to the key values, the leaf node contains a bookma

confidence. Compression: reclaim unused space on a virtual hard disk. This function is used to dynamically expand a virtual hard disk. This function is most useful when a large amount of data is deleted from the virtual hard disk. Merge: merge two disks from the sub-disk and the parent hard disk of Iceland into one virtual disk. However, we generally recommend that: if the current disk allows, we recommend that you first merge the disk into a new vir

Although iSCSI can communicate with any type of SCSI device, system administrators use it almost always to connect to server computers (such as database servers) and

File Storage Technology in Android File storage is a function that every system should have. Android is developed in Java, so its file storage function is basically the same as J2SE. Why Is Nas introduced? If we store large files and images only on mobile phones, we generally use an external

mentioned earlier, and the stateless system is no resource competition and deadlock problems, which enhances the system's robustness, Another advantage of stateless systems is that horizontal scaling is convenient.Here I list the disadvantages of the single primary key generation system not to say I think this solution is completely undesirable, depending on the specific business scenario, according to the author my experience has not yet found a suitable scenario using a separate primary key g

1.ISCSI Brief Introduction?iSCSI leverages Port 860 and 3260 for TCP/IP as a channel of communication. The iSCSI protocol is used to exchange SCSI commands across two computers, allowing the computer to emulate a SAN as a local storage device through fast LAN hubs.??Although ISCSI can communicate with a random type of SCSI device, system administrators almost always use it to connect to server computers (for example, database server) and to
