Table 1. comb (Reference Flowable User Manual )

1 ) General Data Table (2) 
act_ge_bytearray: binary data table, such as the process definition, process template, the flowchart of the byte stream files; 
act_ge_property: attribute table (not used);

 2 ) the history table (8, interfaces HistoryService table operation) 
act_hi_actinst: history node table, storage process instances running in each node information (including the start, end and other non-task nodes); 
act_hi_attachment: historical attachment table, storage accessories historical node uploaded (not used); 
act_hi_comment: history Feedback Form; 
act_hi_detail: table details the history, some of the information storage node operation (not used); 
act_hi_identitylink: historical process staff tables, stored procedures each node candidate, handling personnel information, commonly used in the query has to do the task a person or department; 
act_hi_procinst : historical process instance tables, stored process instance history data (includes a running process instance); 
act_hi_taskinst: historical process task list, task history storage node; 
act_hi_varinst: process history variable tables, stored procedures history variable node Information;

 3 ) user-related tables (4, table IdentityService interface operations) 
act_id_group: user group information table, the node corresponding to the selected candidate information group; 
act_id_info: Extended user information table, the user stores extended information;  
act_id_membership: users and groups Relational tables;
act_id_user: user information table, corresponding to the selected node handle or candidate information;

 4) Process definition, process template correlation table (3, table RepositoryService interface operations) 
act_re_deployment: subordinate information table storing the process definition, template deployment information; 
act_re_procdef: flow definition information table stored in the process definition related description information, but its true content act_ge_bytearray stored in the table, stored in bytes; 
act_re_model: process template information table storing process templates related description information, but the contents stored in the real act_ge_bytearray table, stored in bytes;

 5 ) the process runs table (6 a table RuntimeService interface operation) 
act_ru_task: run-time process task node table, a storage operation task node information flow, it is important to use when used in a query person or department to-do tasks; 
act_ru_event_subscr: monitor information table, not commonly used; 
act_ru_execution: runtime execution process instance table, the information recording operation in the respective branch flow running (when there is no sub-process, and its data is table data correspond to act_ru_task); 
act_ru_identitylink: runtime table art processes, heavy , Used commonly to a query by a person or department to-do; 
act_ru_job: the timing task information scheduled task data tables, stored process runtime; 
act_ru_variable: runtime variable information of each node process variable data table, storing the operation process; 

to sum up

• ACT_RE_ *: 'RE' representatives repository. This includes tables with the prefix "static" information, such as process definition and process resources (images, rules, etc.).

• ACT_RU_ *: 'RU' representatives runtime. These tables store the information when operating, for example, the process instance (process instance), the user task (user task), variable (variable), the job (Job) and the like. Flowable save only runtime data in a running process instance, and delete records at the end of the process instance. This ensures that small and fast runtime table.

• ACT_HI_ *: 'HI' representatives history. These tables store historical data, such as process instance completed, variables, tasks, and so on.

• ACT_GE_ *: general data. In multiple use

2. Process Definition

In the deployment process definition, it is a flow definition to distinguish whether the key is the same process so that the same key successively deployment process definition, it generates a new version of the key corresponding to the process definition. key attribute refers to the process definition id
