Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a data transmission control sequence diagram creation method, and more particularly, to a data transmission control sequence diagram in an online data processing system expressing a communication protocol specification in a specification description language. The present invention relates to a data transmission control sequence diagram creation method that is automatically created.

[Conventional technology]

When designing an online data processing system, first, it is necessary to define a communication protocol and determine a control sequence for data transmission. The specification document that specifies the communication protocol includes, for example, a processing table that describes, in a tabular format, the processing performed by the computer and the next transition state as elements of a matrix in which the state of the computer and the type of event that occurs are rows and columns. (Processing matrix) is used, and a state transition diagram that describes the transition of the state of the computer in the form of a diagram by connecting the transition destination and the processing performed at the transition occurrence condition and the transition destination is used. .

Regarding data transmission in an online data processing system, a data transmission control sequence diagram (time sequence diagram) is often used to represent data communication between a receiving side and a transmitting side via a data line. Such a control sequence diagram is used to visually grasp the flow of data based on a specification document defining a communication protocol, create a flowchart in accordance with the communication protocol of the specification document, and further create a program. You.

Conventionally, a method of creating a flow chart for creating a line control program according to this type of online data processing system is disclosed in, for example, Japanese Patent Application Laid-Open No. 63-94354. The method for creating a flow chart for a line control program described here is that, when a line control program is created, an input screen of a transmission control matrix is displayed on a display surface, and an operator inputs data in data entry items of this matrix. As a result, a transmission control flowchart for each phase is automatically obtained.

[Problems to be solved by the invention]

As described in this publication, a method for creating a flow chart for a line control program from a transmission control matrix has been proposed. A method of verifying a communication protocol by automatically creating a sequence diagram is not considered.

For this reason, the control sequence in data transmission is detected without any omission by detecting the control sequence of the exception case, confirming the validity of the processing performed in the exception case, and by the conversation type with humans. No consideration is given to automatically creating sequence diagrams. Therefore, there is a possibility that the detection and verification of the exceptional case of the communication protocol may be omitted, and the verification of the communication protocol takes time. Further, in all cases, there is a problem that there is a danger that the creation of the control sequence diagram may be omitted.

The present invention has been made to solve the above problems.

An object of the present invention is to provide a data transmission control sequence diagram creation method for automatically creating a data transmission control sequence diagram in an online data processing system expressing a communication protocol specification in a specification description language.

The above and other objects and novel features of the present invention are as follows.
It will become apparent from the description of the present specification and the accompanying drawings.

[Means for solving the problem]

In order to achieve the above object, the data transmission control sequence creation method of the present invention is a method in which the state of a computer and the type of an event to occur are elements of a matrix having rows and columns, and the processing performed by the computer and the next transition state are performed. A method of creating a data transmission control sequence diagram of an online data processing system that expresses communication protocol specifications in a specification description language described in a matrix format in a table format. First, the sequence diagram creation processing means is expressed in a specification description language. The communication protocol specification is input, and the initial state of the own station and the data received from the partner station are input as initial values from the input device in the form of conversation with a human, and the communication protocol specification is analyzed. The processing to be performed by the own station, the transmission data to the partner station, and the state of the own station to be changed next are sequentially determined from the values, and the data transmission control sequence diagram is output to the output device. Characterized by and output.

[Action]

According to the above means, the communication protocol specification expressed in the specification description language described in the form of the processing table (processing matrix) is input to the sequence diagram creation processing means. Then, the communication protocol specification is analyzed by the sequence creation processing means, and the initial state of the own station and the data received from the partner station are input as initial values from the input device in the form of conversation with a human, and the communication protocol specification is analyzed. , The processing performed by the own station from the initial value, the transmission data to the partner station, and the next state of the own station to be changed next are sequentially determined, and these state transitions are output to the output device as a data transmission control sequence diagram. .

That is, when a communication protocol specification expressed in a processing matrix format specification description language is input, the sequence diagram creation processing means analyzes the communication protocol specification, and stores a status record, an event record, and each element in a storage device. Create a processing record. Then, the initial state of the own station and the received data from the partner station are input as initial values from the input device in the form of conversation with a human, and the corresponding state record and event record are searched to determine a processing record.
Next, the processing to be performed by the own station, the data to be transmitted to the partner station, and the state of the own station to be changed next are determined from the processing record.
The state transition determined in this way is processed into a data transmission control sequence diagram on the output device and output. When the output operation of this one state transition is completed, the state of the own station is changed to the state of the own station to which the next transition is made, and the received data from the next partner station is input from the input device in the form of conversation with a human. Wait for In this way, by sequentially outputting the state transitions sequentially as a data transmission control sequence diagram, a data transmission control sequence diagram is automatically created in the form of conversation with a human.

As described above, the transition of each state is sequentially analyzed from the communication protocol specification expressed in the specification description language in the processing matrix format, and a control sequence diagram in data transmission is automatically created in a conversation type with a human. This facilitates detection of an exception case and confirmation of the exception sequence in the data transmission control sequence, and facilitates creation of a control sequence diagram for all cases. Further, the time required for verifying the communication protocol can be reduced by a conversation type with a human.

Next, in step 41, it is determined whether or not there is a matrix record having a matching matrix name in the matrix file. If there is no matrix record with a matching matrix name, the process proceeds to step 42, requesting re-input, and returning to step 40. If there is a matrix record with a matching matrix name, the process proceeds to step 43, where the initial state name and event name are read from the input device. Then, the process proceeds to a step 44, wherein it is determined whether or not the index file has a state record and an event record that match the state name and the event name. If there is no matching state record and event record, the process proceeds to step 45, requesting re-input, and returning to step 43. If there is a matching state record and event record, the process proceeds to step 46, where a processing record corresponding to the state identification number and the event identification number is read from the task file.
