program code is written in PHP. But by carefully reading its database table design instructions and related SQL statements, I have thoroughly understood this clever design concept, in this design, the need to delete nodes and pan at the same layer is added (the original article only provides the list and SQL statements for inserting subnodes ).
Below I try to describe this design scheme with a short text, a small number of charts, and related core SQL statements:
First, let's take a tree as an

Higher reliability and more convenient scalability
The Construction System of NetApp Filers allows it to conveniently, quickly, and effectively store and read large data volumes. The reason is that the unique Appliance

Open build service (OBS) is an open and complete software release and development platform. He provides an infrastructure to create software release packages that support a wide range of operating systems and hardware architectures, as well as plug-ins (add-ons) and application images (appliance images) or the entire Linux release package.
Obs provides a tool set to

Software initialization:before using the device, you must focus on the current configuration or enabled network protocols, which generally require users to provide parameters such as IP address. function Initialization:The Linux kernel provides a range of networking options, and some network options need to be configured separately for each device (such as subsystems that implement QoS), which determine how packets enter the queue and exit queues from the device.

OverviewA virtual device is an abstraction built on one or more real devices. The correspondence between a virtual device and a real device is many-to-many, but not all combinations can be defined or supported by the kernel. Some of the more common virtual devices are listed below:Bonding //bindings, virtual devices bind physical devices so that they are like a single device 802.1Q //ieee standard for establishing a virtual representative of vlanbridging//bridge aliasing interfaces / /a

In encapsulation and interfaces, the private keyword encapsulates an internal member of an object. Encapsulated, the product hides the internal details and is provided only to the user interface (interface). Interfaces are very useful concepts that can assist in our abstract thinking. In real life, when we think of an appliance, we often think of the functional interface of the appliance. For example cups,

At the same time, Oracle recently released a series of cloud-oriented Database and software integration products, including Oracle Database 12c) oracle SuperCluster M6-32 Integration System Oracle SuperCluster M6-32 Engineered System), Oracle Virtual computing device Oracle Virtual Compute Appliance
virtual device is a pre-configured virtual environment that minimizes the work required for normal operation. You do not need to install the operating system, install software, and execute software configurations in this environment. It is pre-configured and can be used at any time. IBM DB2 Enterprise 10.1 Trial Virtual Appliance can run locally on the host computer Through VMware Workstation/Player, or remotely in a VMware vSphere environment. After
The command pattern emphasizes the encapsulation call , which encapsulates the method invocation. By encapsulating the method call, we can encapsulate the operation block, so the object that calls the operation does not need to be concerned about how things work, they just need to know how to use the wrapping method to do it. By encapsulating the method call, we can also do some very clever things, such as logging, or reusing these packages to implement revocation.We use the following example to
The instructions must be executed by specifying the disk device to be checked and the number of disk blocks for the appliance.
