Activiti7 research
Table Design
25 tables (created automatically) = start construction of the table (only when running a new calling process instance) 17 + 8 sheets history table.
Process Repository rule table
ACT_RE_ *: 'RE' represents the repository. The prefix table contains process definitions and process static resources (images, rules, etc.)
1) act_re_deployment deployment information table
2) act_re_model model deployment process design table (for activiti dynamic deployment, XML mapping process documentation)
3) act_re_procdef flow definition data table
Runtime database table
ACT_RU_ *: 'RU' represent runtime. These run-time table comprising a process instance, task data, variables, asynchronous tasks, like running. Activiti only stores the data during the execution of a process instance, these records will be deleted at the end of the process.
1) process execution runtime instance table act_ru_execution
2) run-time process information act_ru_identitylink staff table, the main task of storage nodes and participants
3) act_ru_task runtime task node table
4) act_ru_variable run-time process variable data table
5) Table badmail operation - the number of retries exceeds the job failure ACT_RU_DEADLETTER_JOB
6) run-time events ACT_RU_EVENT_SUBSCR
7) Run-time job ACT_RU_JOB
8) New ACT_RU_SUSPENDED_JOB Work Stoppages Table 6.0 runtime
9) Runtime new ACT_RU_TIMER_JOB timer job table 6.0
10) act_ru_integration ??? I do not know what the new table 7.0
Universal Data Table
ACT_GE_ *: general data for different scenarios, such as storage resource file.
1) act_ge_bytearray binary data table
2) act_ge_property attribute data table storage engine entire process level data, initialization table structure, default insert three records
Historical database table
(ACT_HI_ *: 'HI' represents a history These tables contain historical data such as historical process instances, variables, tasks, etc...)
1) act_hi_actinst history node table
2) act_hi_attachment history table accessories
3) act_hi_comment history table views
4) act_hi_identitylink historical process personnel table
5) act_hi_detail historical details table provide historical query variables
6) act_hi_procinst historical process instance table
7) act_hi_taskinst historic task instance table
8) act_hi_varinst history variable table
other
General Event Log ACT_EVT_LOG process engine record table
Dynamic change information 6.0 ACT_PROCDEF_INFO new process definition
Table difference activiti7 and previous versions
Activiti6 fore and aft ends are not separated, and designed to verify the user & binding couples of the group, in the case of carrying the functional group does not meet the business user & requirements (say substantially not satisfied), as enterprises need to decouple own user & group & permissions check, which can take more time and energy, and which kept some of the pit (open source software are common, you know), and the code is older, use the command mode on the package implementation, leading to extension a lot of trouble. But activiti6 advantage is that there are ready-made interface functions. avtiviti7 to the natural spring of micro-par service, before and after the end of the separation, easy expansion, the disadvantage is less information, many functions need to re-implement themselves.
1. The following table has been abandoned:
ACT_ID_ *: 'ID' represents identity. These tables contain identity information, such as user, group, organization management. Because components comes too simple function has been enabled activi7. Activiti7 using spring security and safety certification.
Organization Table
1) act_id_group user group information table
2) act_id_info extended user information table
3) act_id_membership users and groups correspondence information table
4) act_id_user user information table
The core api interfaces and objects
ProcessEngine
Abstraction process engine, you can get all the services required by such
Service (Service) class
By ProcessEngine acquisition, Activiti will be a different life cycle in different service packages Service, including the definition, deployment, operation. Available service information related to the life cycle through the service class.
TaskService
During the process operation, each task associated operator interface node, such as complete, delete, delegate the like.
RepositoryService
Process definition and deployment of storage-related services.
RuntimeService
Processes running when related services, according to the process as well start the process instance startProcessInstanceByKey.
HistoryService
History Services Interface
service and previous versions of the difference Aitivit7
Removed the following services
FormService : Form Service , used to read and process the form data tasks related
IdentityService : Identity Service , you can manage, query the user, the relationship between the group
Activiti core object
ProcessDefinition correspondence table act_re_procdef query
Execution ProcessInstance table corresponding to the query
Task task list
Query correspondence table act_re_deployment query
ProcessDefinition
ProcessDefinitionQuery
