Section 2. ccflow process element design
Process elements, in summary terms, are the canvas content on the process.
l gallop process engine elements are relatively simple, nodes, connecting lines, labels three kinds.
l There are three kinds of settings: process attribute, node attribute and direction condition.
A process template has a process number, which is a three-digit serial number, such as: 001, 002, 003.
l Each process has multiple nodes, and each node has a node ID, which is the identification of the node. It is composed of the process number + the two-digit serial number converted into int. For example, the process template of 001 has nodes 101, 102 and 103, and a process of 010 has nodes 1001, 1002 and 1003. A process has a maximum of 99 nodes. A process has only one start node, but multiple end nodes are allowed.
When designing the process, the start node cannot be deleted.
l Start node binding personnel, binding positions, departments and other information to determine who can initiate the process.
Section 3. ccflow Design Summary Description:
On the canvas of the process, for simplicity and clarity, the process has three elements: nodes, connecting lines, and labels.
Node: is the activity, the undertaker of the work.
Connection line: is the direction, the connection line is from the node, to the node.
Labels: Explain and explain the meaning of the flowchart, and have nothing to do with the movement of the process.
Examples of flowcharts are as follows:
Section 4. Data storage for ccflow node elements
To better illustrate the storage structure, please refer to the following figure:
Section 5. Primary key of process template
A flow has a number, each number starts from 001, currently supports unlimited addition, flow information is stored in WF_Flow table.
A process has n nodes n
