interface of the file access layer provided by MySQL AB (the access mechanism is called the storage Engine).Now there are many kinds of storage engines, the advantages of each storage engine are different, the most common myisam,innodb,bdb.By default MySQL is using the MyISAM engine, it queries fast, has better index optimization and data compression technology. However, it does not support transactions.InnoDB supports transactions and provides row-level locking, and the application is quite ex

There are 3 standard practice types:1, the earliest practice: The Node ID contains the full path (grandfather id-id-father id-this ID)the ledger account number for the financial services .It's very rarely used today.2. Recursive procedure: Parent ID, this ID (earlier, complete relationship provides recursive ability to get)now more commonadvantages are intuitive and simple, easy to deletethe downside is that the spanning tree needs recursion .3, Direct preservation method: This ID, root ID, numb

Sometimes, you may encounter classes with two or more instance styles and contain tags that indicate the instance styles.Demo: // Tagged class - vastly inferior to a class hierarchy!class Figure { enum Shape { RECTANGLE, CIRCLE }; // Tag field - the shape of this figure final Shape shape; // These fields are used only if shape is RECTANGLE double length; double width; // This field is used only if shape is CIRCLE double radius

. The hardware and software packaged as an enterprise application solution to sell to customers. The deployment of such applications is simple and the hierarchy is relatively shallow. To ensure reliability, deploy one Weblogic Server on each of the two sets of small machines, using a hardware load balancer like F5 in front of the app service, as shown in.Because the minicomputer and the front F5 load balancing hardware are more expensive, so for the r

Mount hierarchy This process corresponds to the Mount-T cgroup-o cpu, cpuset cpuandset/cgroupFirst, it resolves the Mount parameter-O ***: parse_cgroupfs_option and creates a new cgroupfs_root: cgroup_root_from_opts, use cgroup_test_super to determine whether the new mount subsys is the same as the existing hierarchy (the same as their subsys or name). If the same, use the original cgroupfs_root; otherwise,

In the process of developing applications for enterprises, it is very important to break down a large and complex system.
