Create an execution module by translating and combining the source programs for the above using a compiler, execute the created execution module, output an analysis file for the migration asset to be evaluated inputted above, and output the analysis file. and the above-mentioned item Japanese file are input, a specific program (information list output program) is used to evaluate the difficulty level of the migration asset to be searched for, and the evaluation result is output to a form.

[Industrial application field]

The present invention is a project migration method (new development).

A method for evaluating (ascertaining) the difficulty level of migration assets to determine the conversion (conversion) and estimate the load of the project. With the recent diversification of computer systems, assets used in other companies' computer systems, such as source programs, There are many cases where various definitions indicating the structure of the Job Control Language Card (JCL) database, form formats, etc. are being migrated so that they can be used in one's own computer system, and the initial stage of migration for such projects is increasing. , we can accurately determine the migration method (new development or conversion) and estimate the migration load without requiring experienced migration personnel.

Moreover, it is required to be able to obtain the information quickly.

[Prior art and problems to be solved by the invention] FIG. 3 is a diagram illustrating a conventional migration asset difficulty evaluation method.

Traditional migration assets, such as the aforementioned source programs,
Job control language card (JCL), data hese configuration, lil! Evaluation (determining) (b) of the difficulty level when migrating various definition bodies indicating the format of vote, etc. is carried out by a person with skill (technical ability) with migration experience who conducts interviews with asset managers, and Using a general-purpose utility, the real asset can be analyzed using character strings, such as what instructions the real asset has, what utilities it has, whether the data structure is hierarchical, and various program keys. The order of.

We conducted an investigation (a) of character strings indicating how the keys were arranged, etc., and looked at the results.

Therefore, in the conventional method, a person with experience in migration is required, but there is a problem that it is difficult to secure a person with a wealth of experience, and interviews with people with experience in migration are difficult due to the subjective aspects of the person with experience in migration. There are problems such as the problem of lack of credibility due to the lack of reliability, the time-consuming character string investigation using general-purpose utilities, and the problem that determining the results depends on the technical ability (skills) of the person with experience in migration. there were.

In view of the above-mentioned conventional drawbacks, the present invention employs people with migration experience to determine the migration method (new development, conversion) of a project and to evaluate (ascertain) the difficulty level of migration assets when estimating the load of the project. Automatically performs everything from investigation to evaluation (determination) of migration assets without the need for migration, determines the migration method, and accurately estimates the project load! +11.
Another object of the present invention is to provide a method and device for evaluating the difficulty of migration assets that can be performed quickly.

[Means to solve the problem]

FIG. 1 is a diagram illustrating the present invention in detail.

The above problems are solved by the migration asset difficulty evaluation method and device configured as follows.

Based on a plurality of migration assets, for each of a plurality of items 10 constituting the migration assets, an item consisting of a difficulty level 11 when migrating the migration assets and a keyword I2 characterizing the item 10 is created. In order to search for the difficulty level of the migration asset by configuring the language file 1 and manually inputting the configured item Japanese file 1 and the instruction parameter 2 that instructs the evaluation target item of the migration asset to the generator ■. Generate a source program 3, translate and combine the generated search source program 3 with a compiler ■ to create an execution module ■, execute the created execution module Output the analysis file 6 for the target migration assets, input the output analysis file 6 and 1 above item Japanese file 1, and use a specific program (information list output program) to migrate the above search target. It is configured to evaluate the difficulty of assets and output the evaluation results to a form 7.

[Effect]

That is, according to the present invention, an item Japanese file is created in which research know-how is filed based on assets transferred from the past to the present.

The item Japanese file is for each difficulty evaluation target item (e.g. new instruction) (actually coded) that exists in the actual asset (e.g. source program) to be migrated. A search keyword that specifies (for example, a specific instruction name that exists in the above program and is the target of evaluation at the time of migration, and corresponds to the aforementioned character string) and an evaluation value (difficulty level at the time of migration). The keyword is used when generating a search program, and the difficulty level is used to calculate the evaluation of the migration asset in the information list output process.

■) First, in the generator ■, input the above item Japanese file and the parameters (consisting of the search program name and the difficulty level item code (for example, 5 digits)) that specify the search target, and then select the difficulty level of the evaluation target item. Generate a search program (source module) to search for degrees.

2) In the next step, Compile & Link ■, compile and link (translate, combine) the search program (source module) generated by the generator ■ above,
Create an execution module (object).

3) The execution module, that is, the search program ■,
Enter the migration asset to be searched, for example, a source program, and select the name of the source program to be searched from among the source programs that are the migration asset.

Search for keywords (new instruction name, etc.) and create an analysis file.

4) Based on the analysis file output by executing the above search program ■ and the above item Japanese file, for example, the information list output program ■ evaluates the difficulty level for each source program to be searched above, e.g. Based on the keyword, the item Japanese file is searched, the difficulty level for each keyword (in this example, the instruction name) is totaled, and the difficulty level and difficulty rank (
8 to E) and output the evaluation results to an information list (form).

Therefore, if the transition asset difficulty evaluation device of the present invention is used,
Simply enter the parameters that indicate the search target, and the difficulty level when migrating the relevant migration assets.

The rank is output in the form of a report, which has the effect of making it possible to quickly and accurately evaluate the migrated assets without requiring a person with migration experience, unlike in the past.
