When you create a process with Jawe, the related activity is placed in the corresponding role. In order to assign specific tasks to specific users, it is necessary to map roles to specific users when starting the process. Shark can map a role to a single user, or you can map a role to a user group. If you map to a separate user, the role's tasks will only appear in the user's task list; If you map to a group of users, the role's tasks appear in the Task list for all users of the group, and if on

A one-to-many relationship can be divided into unidirectional and bidirectional.One-to-many relationship unidirectionalOne-way is to find the other side only from the side, usually from the master class to find the Class (table) that owns the foreign key. For example, a mother can have multiple children, and the child has a mother's primary key as a foreign key. The relationship between mother and child is a one-to-many relationship. If you want to act on the mother's information and also respon

Write in front: Because address mapping involves setting access to various registers, Linux has different methods for addressing different architecture processors, for example, for I386 and later 32-bit Intel processors using a 2-level page table map in page-map. For IA64 processors, 3 levels of paging are used. For other types of processors, such as MK68000 and many other processors, the segment mapping is

Brief introduction:The mapping between the POJO class and the relational database can be defined with an XML documentWith the POJO class's database mapping file, Hibernate can understand the relationship between persisted classes and data tables, as well as the relationship between persisted class properties and database table columns.Hibernate will generate various SQL statements based on this

As shown in the following:In this picture, the reader can see that there is a sky in the scene, and no matter how the game character moves in the scene, it cannot be close to the sky. By adding such effects, the game world is more colorful and closer to the real

One, inheritance mappinginheritance is an object-oriented feature that implements the use of code, as well as inheritance in relational models, which can be viewed as an enumeration relationship in which many subtypes can be enumerated, and these subtypes and parent objects form inheritance relationships. Most of them can be enumerated as an inheritance map, so this enumeration relationship can be seen as an inheritance map, for example, an animal is an abstract class, which is the parent of oth

Preface:Object-Relational mapping (ORM), which is a technology to solve the mismatch between object-oriented and relational databases, is essentially the conversion of a database from one form to another, as a result of the development of object-oriented software development methods. ORM automatically persists the exclusive use of a Java program into a relational database by using metadata that describes the mappi
