Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a database for all information of data (tool type, specifications, printer output information, etc.) held by various platforms,
The present invention relates to a network system for automatically performing the most efficient work based on this database for user needs.

[0002]

2. Description of the Related Art Conventionally, when creating a program in program development, it is necessary to determine a development method at the stage when the program specification is determined, and first, it is necessary to collect various information as an element for determining the development method. FIG. 7 is a flowchart showing a flow of program development using a conventional network system.

First, a development language as a program development method is selected (S100), and the development environment (compiler / linker / debugger etc.) as shown in FIG. 7A relating to the development language selected in S100 is sufficient. A detailed survey is performed (S101). Then, as a result of the survey in S101,
If there is no information or know-how for the development language selected in S100, the process returns to S100 and selects a development language again.
As a result of the investigation in S101, if the user has sufficient information and know-how for the development language selected in S100,
The development language is determined as a development method (S102).

Here, in S100 to S102,
For example, it is necessary to investigate and examine whether or not there is a record of program development in the selected development language, whether or not there is any reference material, and whether or not there is a fatal problem.Only if it is judged that a sufficient development environment is in place in this investigation Thus, the actual program creation is started.

[0005] Then, based on various data collected when determining a development language as a program development method in S100 to S102, data necessary for program development is arranged and a program specification is created (S103). This S
The program specification created in 103 is used as a basis for future program development.

At the stage of creating a program specification, there is a case where parts (modules) are investigated in addition to the data of the development environment from the viewpoint of improvement of work efficiency and improvement of quality. In addition, it is necessary to investigate related components from the data shown in FIG. 7A, and to check detailed information of components and defects.

[0007] Based on the program specifications created in S103, coding work is performed in a development language (S104), and a key file is input using an editor to create a source file (S105). Then, the source file in the development language created in S105 is converted (compiled) into a machine language (S106), and several files (module groups) converted into the machine language in S106 are connected (link), Is created (S107).

However, there are many versions of the tools used in S105, S106, and S107, and when work such as changing a part of a program module is performed, work is performed using a tool having the same version as another module. There is a need. This is because normal operation may not be performed because the protocol of the generated machine language differs depending on the version. Such unification of versions is an important point in program modification work.

Then, it is checked whether the program created in S107 operates as designed, and if there is an error in the program, the error is found and corrected (debugged) (S107).
108), S1 until debugging in S108 ends.
04 to S108 are repeated (S109). And S1
If it is determined in step 09 that the debugging has been completed, a comprehensive operation check list of the program is created (S110).
A test is performed to determine whether the program operates properly comprehensively (S111).

If the created program does not operate normally in the test at S111, the program returns to S104.
Returning to step S111, if there is no problem in the test of S111, the program is completed (S112).

As described above, there are several versions of tools such as a compiler, a linker, and a debugger for compiling, linking, and debugging, and the machine on which the tool is installed is distributed in load. At present, it is distributed to a plurality of machines for the purpose. Until now, various tools and their installed machine information were managed independently, such as personal memos and files describing map information. Therefore, after the specific program creation work is started, the independent data must be searched and searched, which requires a great deal of research man-hours.

Next, a description will be given of an operation when the program creating process as shown in FIG. 7 is specifically performed by a machine using a network system. FIG. 8 is a diagram showing a specific example of program development using a conventional network system. In the figure, reference numeral 11 denotes a server computer serving as a compile server having a cross compiler, reference numeral 12 denotes a server computer serving as an application server having an application associated with program creation, and reference numeral 13 denotes a server computer serving as a print server for printing a program list. , 14 to 16 are clients connected to the print server 13 and clients A, B, and C, respectively.

First, a programmer operating the client A 14 extracts necessary information from various kinds of information as shown in FIG. 7A, specifies an appropriate compile server 11, and performs an operation. 17 is the client A14 at this time
Indicates a path for requesting the work to the compile server 11.

Further, the programmer operating the client B15 determines the application server 12 in which the application required to carry out the accompanying work of program creation is installed from various information as shown in FIG. 7A. Extract and identify and implement work. 18 indicates that the client B15 at this time
Of the application server is shown.

Further, the programmer operating the client C16 extracts the necessary information from various types of information as shown in FIG. 7A by using the print server 13 in which a print output function is installed in order to output a program list. Then, referring to the output information of the printer 20 which the print server 13 grasps, an arbitrary printer is specified and the operation is performed. Reference numeral 19 denotes a route at which the client C16 requests the print server 13 for work.

[0016]

In a conventional program development using a network system, various tools and their installation machine information as shown in FIG. 7A are used to store personal notes and map information. The described files are managed independently. And
Such information is dispersed in various media and storage locations, and it is difficult to investigate and extract necessary information. This includes, for example, which server has the compiler and other tools on it, several versions of the compiler, whether the compiler has never failed, where to find the compiler documentation, and who manages it. This is because there is a lot of necessary information such as whether the information is collected, and even if the respective information is accumulated, it is quite difficult to collect all the information, and many man-hours are required.

[0017]

A network system according to the present invention enables a plurality of server computers mounted with a program development tool, a print server for print output, and a plurality of client computers to communicate with each other via a network. At least one database that collects information on development tools installed on a plurality of server computers and a printing status by a print server in a simple network system;
Means for providing information in the database as required by operators of a plurality of client computers.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a flowchart showing a flow of program development using a network system according to an embodiment. As shown in FIG. 1, in this embodiment, various development method information conventionally required for program development is converted into a database as information of the entire network, and by utilizing the database, it is possible to reduce the number of investigation steps to date. The network system has a network database management system 29 (tentative name: NetworkDatabeseManager: NDM, hereinafter referred to as NDM) aiming at improvement of work efficiency and quality.

With this network system, the programmer can start from the stage of determining the development environment for program creation.
The development environment is determined by referring to the DM, and all information is clarified at the early stage of development, so each work process always goes through the project-specific database created by the NDM without being aware of each server or printer. You will be able to perform tasks. In addition, the database has been enhanced so that it can respond to requests from any angle.

Here, the operation of the NDM will be described.
FIG. 3 is an explanatory diagram for explaining an operation of the NDM in FIG. 2. In the figure, reference numeral 21 denotes information necessary for a series of program creation operations, and this information includes static information such as version information of various tools and dynamic information such as print output information. Reference numerals 22 to 24 denote specific containers (databases) in which such information is stored. Reference numeral 22 denotes static information in which tool version information and its installed machine information, and machine information of parts (modules) are registered. Database group 23 is dynamic information whose status changes in real time, such as print output information and remote compilation information, and database 24 is information on a program to be developed, change history and know-how information of a related program. Is a database group in which is stored.

Reference numeral 25 denotes a database generated by searching / extracting information from each database group by the NDM 26 for managing and controlling the database of the entire network environment as a project-specific database. A series of program creation operations are performed based on the database 25.

First, the NDM 26 has the database group 2
A database 25 unique to the project is generated from the data groups 2 and 23 according to the needs of the user, and the dynamic information is changed at regular intervals in the database 25. Search / extraction from these database groups is performed. It has functions to control / manage / organize / create a project-specific database and perform all regular maintenance.
When the programmer wants to refer to the development environment of the project, the client 27 can always extract necessary information from the project-specific database 25 via the NDM 26.

Next, the flow of program development by NDM will be described with reference to FIG. Here, as shown in FIG. 1, the basic flow of program development is the same as in the conventional example. First, as before, the programmer collects various kinds of information in order to determine a development method before starting program development, and this information source is set to ND as shown in FIG.
This is performed by making an inquiry to M29.

If there is no database 31 specific to the project to be inquired, the NDM 29 retrieves and extracts information required by the programmer from various database groups as shown at 30 in FIG.
In this way, from the stage of collecting information to determine the development method,
The development method is determined using NDM29.

If the data extracted by the NDM 29 at this time is registered as a database for supporting future project development, a project-specific database 31 can be generated. Then, in the preparation of the program specification, the data conversion program is executed from the NDM 29 using the project-specific database 31, thereby executing the "program development environment" of the program specification.
It can also be applied to automatically generate items.

Then, as shown at 33 to 37 in FIG.
Compile, link, debug, checklist,
In the development of each program such as a test, information on the version of a tool such as a compiler, a linker, a debugger, and the machine on which the tool is installed is automatically acquired based on the project-specific database 31 via the NDM 29, The work of creating a program is automatically performed.

Next, a description will be given of an operation when the program creating process as shown in FIG. 1 is specifically performed by a machine using a network system. FIG. 3 is a diagram showing a specific example of program development using the network system of this embodiment.

In the figure, reference numeral 38 denotes a server computer serving as a database control server in which an NDM for controlling a network database and a project-specific database resides. 39 is a server computer serving as a compile server having a cross compiler,
Reference numeral 40 denotes a server computer serving as an application server having an application associated with program creation, and reference numeral 41 denotes a server computer serving as a print server for printing a program list, which holds output information of a connected printer 45 in real time. ing. Reference numerals 42 to 44 denote clients A, B, and C.

First, the programmer operating the client A42 requests the database control server 38 in which the NDM resides to perform a compiling operation. Then, the requested database control server 38 refers to the project-specific database 46, specifies the compile server 39 having the cross compiler, and performs the process using the appropriate version of the compiler.

Further, the programmer operating the client B43 performs ND operations in order to carry out the work associated with program creation.
Database control server 38 where M resides
To ask. Then, the requested database control server 38 transmits the project-specific database 46.
To specify an appropriate application and perform an appropriate process.

When the programmer operating the client C44 needs to print the list in the middle of the work, it requests a printout request to the database server 38 where the NDM resides. Then, the requested database control server 38 refers to the project-specific database 46 and outputs to the printer 45 managed by the appropriate print server (NDM uses a printer that takes into account the output status of the printer and printer location that change in real time). Select and execute processing). The output information of the printer 45 is managed by the print server 41, and this output information is
This is reflected in the project-specific database by the DM.

Here, updating of the database by the NDM will be described. FIG. 4 is an explanatory diagram for explaining updating of a database by NDM. In the figure, 47
Are various servers, 48 is a network database, 4
9 is a print server, 50 is a network database, 51 is an NDM, 52 is a project-specific database, and 53 to 55 are clients.

There are two types of data managed by the NDM 51: maintenance information that changes data when a tool or the like is installed in each server, and real-time information that constantly changes, such as print output status. When a change occurs on the server 47 side, the database 48 is updated from the various server sides or the NDM 51. The print server 49 reports the constantly changing print status to the print server side or the NDM 5.
The data is transmitted or received from the first side at regular time intervals and the database 50 is changed.

The NDM 51 periodically checks the database 48 or the database 50, and reflects any changes in the items of each database in the project-specific database 52. These databases can always be referenced from each client 53-55 at any time,
It can be used as a reference when deciding on a development method or as data for building a development environment.

Next, updating of real-time information and maintenance information by the NDM will be described. FIG. 5 is an explanatory diagram for explaining the update of the real-time information of the database. Here, the update of the information of the print server is shown. FIG. 6 is an explanatory diagram for explaining updating of the maintenance information of the database. First, in the case of real-time information from a print server or the like, when the NDM 56 has reached a predetermined time, an inquiry is made to each print server 57 to collect print status data and change the print status database.

In the case of maintenance information of a server or the like, the NDM 58 periodically updates the database 5 of each server.
9 is checked, and when a tool is added or deleted in each server 59, the NDM 58 checks the database of each server 59 and updates the changed data to a database managed by the NDM 58.

In this embodiment, information (data), which has been dispersed by various media and experiences, is digitized and centrally managed as a database, and a manager system such as an NDM is connected to the database. Therefore, it is possible to eliminate the investigation time at the time of creating the program, and the programmer can work without investigating and accessing a target server.

[0038]

As described above, according to the present invention, at least one database which collects information on development tools mounted on a plurality of server computers connected to a network and print status by a print server, Means for providing the information in the database as required by the operators of a plurality of client computers connected to the network, so that information (data ) Can be digitized and centrally managed as a database, so that it is possible to eliminate the time required for the programmer to investigate various information during program development.
