First, the conceptA tablespace is a logical part of a database.Physically, the database data is stored in the data file;Logically, the database data is stored in a table space, and the tablespace consists of one or more data files.Second, the logical structure of the databaseThe logical structure in Oracle includes table spaces, segments, extents, and blocks.Note that the database is composed of table space, and the table space is composed of segments, and the section is composed of the region,

the amount of concurrency is not infinitely large, It's pretty much the time you need to use Message Queuing. For example, when you write a log, a client has more than one operation area to write logs, and there are many clients to write, obviously concurrency can not be infinite, so you need to write log requests into the message queue, the consumer side to take out the queue of messages written to the log.I.

Simulating asp.net with php (as the mainstream development language) is unlikely, especially for php (as the mainstream development language) this is even more difficult for Object-Oriented dynamic languages. in these cases, simulation means that we can use this example to understand the operating mechanism of asp.net (the most powerful development language of Microsoft ). the code is very simple. You do not need to elaborate on it. This test is run on win2000, iis (Microsoft's WEB server platfo

basic creation functions. Database_nameThe name of the new database. The database name must be unique in the SQL Server instance and comply with the identifier rules. Unless the logical name is not specified for the log file, database_name can contain a maximum of 128 characters. If the logical log file name is not specified, SQL Server will append the suffix to database_name to generate logical_file_name and OS _file_name for the log. This limits database_name to 123 characters, so that the na

Real life of the real object did not find, in JavaScript left an object to another object, and I was dizzy to the unintelligible. Personnel are complex and people are difficult to understand. Although I am a liberal arts student, but also not good at Blarney. Or in the JS inside look for the object. So we start with the JS object today. Yesterday, we talked about the data types in JS are divided into two kinds, primitive type, object type. The composition of the object type is made up of b

Oracle foreign key cascade deletion and cascade updateCascading Deletion Oracle has three behaviors: no action (similar to RESTRICT), CASCADE, and set null. The following uses the student-class as an example to describe how to delete Foreign keys in different situations. A student belongs to a class and the primary key of the class is the foreign key of the student. -- Class table crate table TB_CLASS (id number not null, -- class primary key name VA
