Tags: report data source cross-Library collectorThe data of many reports in actual application originates from many different types of databases, and the report data source cross-database is the norm in report development. There are many ways to implement this type of cross-Library associated report, but there are problems like that. using the report Tool's own multi-source correlation featureMost mainstream reporting tools now support multiple data source associations, which in some ways are re

The introduction to menu and file association in linux desktop has never understood the problem of linux desktop menu and file association. now I have studied and written a summary.

Text/figure Peng YiThe file association method was implemented earlier by the "glacier" program. For self-protection purposes, "glacier" associates TXT files with EXE files. ). The specific implementation is to modify the REG_EXPAND_SZ type value of the registry key "HKEY_CLASSES_ROOTxtfileshellopencommand. The default value is "% SystemRoot % system32NOTEPAD. EXE % 1". "% 1" indicates the text file name to be opened. This

PHP development framework YiiFramework tutorial (27) database-example of association with ActiveRecord We have learned how to use Active Record (AR) to obtain data from a single data table. This section describes how to use AR to connect multiple related data tables and retrieve the joined dataset. To use relational AR, we recommend that you define the primary key-foreign key constraint in the table to be associated. These conventions can help ensure

There are two table rule tables and group tables: tb_rules， tb_group This is the auth permissions of the two tables, obviously they are many-to-many relationships, a rule can belong to more than one group, a group can have more than one rule; According to reason, there should be an association table.tb_group_rules(group_id，rule_id) But thinkPHP the auth class inside does not have the correlation table, is such the tb_group inside has a rule

Objects in the objective world are rarely isolated. For example, a teacher is often associated with the students being taught. If an instance of a teacher has been obtained, you can directly obtain all the students corresponding to the instructor. If you have an instance of a student, you can also access the corresponding teacher of the student.Association. AssociationIt is the most important knowledge of Object-Oriented Analysis and object-oriented design. hibernate can fully understand this

In chapter 1, we have a perceptual knowledge of hibernate. Understand the lifecycle of an object. Http://blog.csdn.net/wiksys/article/details/7934380 In this chapter, we will learn the associations between objects. First, recall. How do we deal with associations in the database? The foreign key )! By the way, it is the foreign k

Class A in a method; Association) It represents a strong dependency between two classes or between classes and interfaces, such as my friends and I; this relationship is more dependent than the dependency relationship, with no dependency relationship. The relationship is not temporary and is generally long-term. In addition, the relationship between the two parties is generally equal, and the relationship can be one-way and two-way; it is manifested

Like TCP, sctp is also connection-oriented, so there is also an associated handshake process for establishing and terminating. However, the handshake process of sctp is different from that of TCP. Four-way handshake When a sctp association is established, the following situation occurs (similar to TCP ). (1) The server must be prepared to accept external associations. This is usually done by calling the socket, bind, and listen functions, called

Multi-Data Source hybrid scenarios are very common in report development, such as scenarios where data comes from a mix of multiple databases, databases, and files. Traditional report tools often use two methods to solve this problem: 1. Unify data into a single database to avoid cross-database queries or mixed database file queries; 2. Use advanced languages to customize datasets for reports and perform multi-data source Association operations in the
