cascade cms

Because the company's framework is not open source, but has always been interested in research framework, so took an open-source framework, and this open-source framework is Kooboo CMS. First I can not use words to describe my praise of this CMS, in short, we know a little, this CMS is a very good CMS, the function is

preliminary guide, not a final one. For the latest information, refer to the documentation for the operating system. MySQL table maximum can achieve how much: http://dev.mysql.com/doc/refman/5.1/zh/introduction.html#table-size In fact, the amount of data that MySQL can withstand is mainly related to the structure of the datasheet, not a fixed number. The structure of the table is simple, the amount of data that can withstand is relatively larger than the structure of the complex. According to t

Cascade: set the level of cascade operations. Inverse: whether to discard the maintenance of cascade links. The cascade attribute has the following values: 1. None: ignore other associated objects. Default Value. 2. Save-Update: when the session uses the SAVE (), update (), saveorupdate () method to save or upd

How to implement cascade in row editing of the datagrid ?, Datagrid implementation It is still a cascade problem, but this time, it is in the datagrid, so the difficulty is definitely higher than the cascade in form. However, as long as you are familiar with the datagrid API, the problem can be easily solved. The key point is -- editor, which relies on the datagr

A lot of people can't tell the major GC, the full GC concept, in fact I checked the information, and did not find a very accurate definition of major GC and full GC concept. The confusion between these two concepts may be confusing: Does the full GC cause minor GC?After a series of lookups and analysis of the performance of the JVM, it is possible to define the full GC and major GC next, which is a concept and justification.This article major gcs–separating myth from Reality Basic discussion is

Mysql cascade operations (instances) and mysql-level operation instances MySQL only supports the InnoDB Storage engine for Foreign keys. When creating foreign keys, the parent table must have corresponding indexes, when a sub-Table creates a foreign key, the corresponding index is automatically created. When creating an index, you can specify operations for the child table When deleting or updating the parent table, including RESTRICT, NOACTION, set

It is still a cascade problem, but this time, it is in the DataGrid, so the difficulty is definitely higher than the cascade in form. However, as long as you are familiar with the DataGrid API, the problem can be easily solved. The key point is -- editor, which relies on the DataGrid to implement the editing function. Implement current edits first For example, to edit a column in the DataGrid, You need to

Premise:Inverse: Responsible for foreign key maintenance;Cascade: Responsible for adding and deleting changes to records;Basis:The "inverse" property in Hibernate has only two values of "true" and "false". "True" indicates that the power to maintain the relationship is given to the other party, "false" means that the maintenance power is not surrendered (the default value).Hibernate "Cascade"-the written ex

1, exactly where to use cascade= "..."?Cascade property is not a many-to-many relationship must be used, with it just let us in the insertion or deletion of the image is more convenient, as long as the source of cascade to insert or delete, all cascade relationship will be automatically inserted or deleted. To be able

The full name of ORM is object/Relation Mapping, that is, object relationship ing. Since ORM is developed, it is inevitable to involve the relationship between objects. Through the abstraction of object-oriented ideas, we can define the relationships between objects as follows: One-to-one Multiple-to-one (one-to-multiple) Many-to-many We can easily create an enumeration for object relationships.

1. Introduction In the previous section, we talked about extended attributes. To put it bluntly, we can click Teacher from the Subject and click the List of Subject from the Teacher. in practice, we usually Delete Teacher, so the course offered by this Teacher is useless, because Subjcet has no teachers. so we hope that the courses we delete when deleting the Teacher will also be deleted. therefore, cascade operations are available. Ii. Logical R

When a parent-child (Head-detail) relationship exists for both parties, and Cascade is All-delete-orphan, the parent object has the following features: 1. When the parent object is saved or updated, Cascade saves or updates all associated child objects, equivalent to Cascade Save-update 2. When the parent object is deleted, C
