Description

Software specifications exploitation householder method and software specifications exploitation auxiliary device

Technical field

The present invention relates to the technology of a kind of assisting software development.

Background technology

The corresponding relation of the condition before sometimes performing with software and the result after its execution defines software Specification.The corresponding relation of this condition known and result can be with being referred to as decision table (decision table) Sheet form show, be frequently used to engineering of software development.Decision table has several different description shape Formula, even if being the decision table that description form is different, the semanteme of the corresponding relation of expression condition and result is also The same.And, decision table is sometimes referred to as conditional matrix or checks other titles such as list.

By using this decision table to represent specification, the corresponding pass of condition and result can be described like clockwork System, also has the effect that the pattern easily finding condition is omitted simultaneously.On the other hand, specification based on decision table Description has the disadvantage that.That is, there is the increase along with condition element, pattern increases and decision table expands, from And the problem that readability declines.

As the prior art of this problem of solution, patent document 1 discloses that one is carried out by segmentation decision table Statement prevents the method for readable decline.

If using prior art disclosed in patent documentation 1, decision can be shown by readable high form Table.But owing to the description amount of decision table is constant, the input quantity that therefore can produce decision table increases, generates work The problem that the problem of Shi Zengjia and the memory capacity in order to preserve needed for decision table increase.As solving this problem Prior art, patent document 2 discloses that a kind of method, i.e. by generating certainly from the description of propositional form Determine table, thus cut down the generation man-hour of decision table.It addition, open following methods, i.e. by carrying from decision table Carry out after taking the description of propositional form preserving/showing, thus cut down for depositing needed for preserving/show decision table Storage capacity.

But, when specification is contradictory or omit time, show with the specification of decision table form compared with, based on proposition The specification of the description of form shows have the shortcoming being difficult to visual confirmation contradiction or omission.It is to say, want When being carried out visual confirmation contradiction by the display of decision table or omitted, the method represented by patent documentation 2 does not has Effect.Therefore, specification is carried out for the visibility of the contradiction or omission that improve specification with decision table form During display, owing to the prior art represented by patent documentation 2 can not be applied, so can not solve along with decision The extension of table and problem that memory capacity needed for the display of decision table increases.It addition, patent documentation 2 Shown prior art, had been internally generated decision table before the specification of description based on propositional form shows. Therefore prior art also has the extension along with decision table, the memory capacity needed for the generation of decision table and process The problem that time increases.

Fig. 6 is the example that the contradiction that contradiction inspection portion 105 logs in checking result storage unit 109 checks result Son.

The inspection result 601 that contradiction checks is by checking object-rule 602, comparison other rule 603, checking 604, the specification 605 of contradiction and reconcilable specification 606 are constituted as a result.

Check that object-rule 602 and comparison other rule 603 represent and proposition rule respectively becomes contradiction inspection The proposition rule of the object looked into and the proposition rule becoming its comparison other.Check that result 604 represents that inspection is right As the contradiction of rule 602 and comparison other rule 603 checks result.The specification 605 of contradiction represents in inspection With the specification of the specification contradiction represented by comparison other rule 603 in rule represented by object-rule 602. On the contrary, reconcilable specification 606 represent in checking the specification represented by object-rule 602 with comparison other The rule reconcilable specification of specification represented by 603.

For example it is assumed that as checking that object-rule 602 provides proposition rule 301, as its comparison other Rule 603 and provide proposition rule 302.At this moment, contradiction inspection portion 105 logs in " contradictory " as inspection Come to an end fruit 604.Meanwhile, as the specification 605 of contradiction, log in following specification, i.e. " when " insurance adds With or without " it is " adding ", and when " volume is paid in insurance " is " more than 20,000 yen ", " subsidy " is " there is payment " ".Further, as reconcilable specification 606, log in following specification, i.e. " when " insurance There was added nothing " it is " adding ", and when " volume is paid in insurance " is not " more than 20,000 yen ", " subsidy Gold " be " having payment " ".

Fig. 7 is the flow chart of the step example representing that contradiction checks.

Process shown below is that the CPU202 possessed by software specifications exploitation auxiliary device 201 is being deposited The program performed in reservoir 203 realizes.Further, this program is by the various actions carrying out following description Code is constituted.

CPU202, by performing contradiction inspection portion 105, obtains arbitrary 2 from proposition rule storage unit 102 Individual proposition rule, respectively as checking object-rule and comparison other rule.The inspection object-rule obtained Log in respectively with comparison other rule and check that the inspection object-rule 602 of result storage unit 109 is with the most right As in rule 603 (step 701).

The condition part of the condition checking object-rule that contradiction inspection portion 105 obtains with reference to expression and expression ratio The condition part of the condition of relatively object-rule, it is determined that whether the condition part of both sides and is deposited.When condition part and when depositing, Knot referring next to the result in the result portion and expression comparison other rule representing the result checking object-rule Really portion, it is determined that whether the result portion of both sides and deposits.When condition part and deposit and result portion is not and when depositing, in inspection The inspection result 604 of fruit storage unit 109 that comes to an end logs in " contradictory ", performs step 703.Work as condition Portion not and deposits, or condition part deposit but result portion is also and when depositing, in the inspection checking result storage unit 109 Log in " not contradiction " in 604 as a result, log in reconcilable specification 606 and check object-rule and terminate Process.The inspection of described compatibility can use SAT solver.Such as proposition rule 301 and proposition The condition part of rule 302 is also deposited and result portion not and deposits, and therefore logs in " contradictory " in checking result 604, Perform step 703.(step 702).

Contradiction inspection portion 105 check whether there is occur in comparison other rule does not appears in inspection right As the condition item in rule.Step 704 is performed when there being the condition item meeting described condition.When not having Step 706 is performed when meeting the condition item of described condition.Such as using proposition rule 301 as checking object Rule, during using proposition rule 302 as comparison other rule, the condition item of " volume is paid in insurance " meets Described condition, therefore performs step 704(step 703).

Contradiction inspection portion 105 by that detect in step 703, occur in comparison other rule does not go out Check now that the condition item in object-rule is being examined with the value identical with the value occurred in comparison other rule The condition part looking into object-rule carries out logic product combination.In the case of the most above-mentioned example, by " " insurance is paid Na E " be " more than 20,000 yen " " condition carry out logic product combination at the condition part of proposition rule 301, Worked as " insurance there was added nothing " be " the most complete " and " volume is paid in insurance " be " more than 20,000 yen " Time, " subsidy " is the description of " having payment ".(step 704).

The specification 605 as contradiction that describes generated in step 704 is logged in inspection by contradiction inspection portion 105 In result storage unit 109 (step 705).

Contradiction inspection portion 105 will check that the object-rule specification 605 as contradiction logs in inspection result and preserves In portion 109, end processes (step 706).

Contradiction inspection portion 105 by that detect in step 703, occur in comparison other rule does not go out Check now that the negative value of the value to occur in comparison other rule of the condition item in object-rule is checking The condition part of object-rule carries out logic product combination.The most in the case of the above-described example, by " " insurance is paid Na E " be not " more than 20,000 yen " " condition carry out logic product knot at the condition part of proposition rule 301 Close, worked as " insurance there was added nothing " be " adding " and " volume is paid in insurance " be not " 20,000 yen Time above ", " subsidy " is the description of " having payment ".(step 707).

The description generated in step 707 is logged in inspection as reconcilable specification 606 by contradiction inspection portion 105 In the fruit storage unit 109 that comes to an end (step 708).

Fig. 8 is the example of the rechecking result that rechecking portion 106 logs in checking result storage unit 109 Son.

The inspection result 801 of rechecking is by checking object-rule 802, comparison other rule 803, checking 804, the specification 805 of repetition and unduplicated specification 806 are constituted as a result.

Check that object-rule 802 and comparison other rule 803 represent to respectively become in proposition rule and repeat inspection Check the proposition rule of elephant and become the proposition rule of its comparison other.Check that result 804 represents and check object Rule 802 and the rechecking result of comparison other rule 803.The specification 805 repeated represents right in inspection The specification that specification in specification as represented by rule 802 and represented by comparison other rule 803 repeats. On the contrary, unduplicated specification 806 represent in checking the specification represented by object-rule 802 with compare right The unduplicated specification of specification as represented by rule 803.

For example it is assumed that as checking that object-rule 802 provides proposition rule 301, as its comparison other Rule 803 and provide proposition rule 303.At this moment, rechecking portion 106 is as checking that result 804 is stepped on Record " having repetition ".Meanwhile, as the specification 805 repeated, following specification is logged in, i.e. " when " insurance adds Enter with or without " be " adding " and " volume is paid in insurance " be " more than 20,000 yen " time, " subsidy " It is " having payment " ", as unduplicated specification 806, log in following specification, i.e. " when " insurance there was added Nothing " it is " adding " and " volume is paid in insurance " when not being " more than 20,000 yen ", " subsidy " is " there is payment " ".

It addition, described rechecking portion 106 not only checks the repetition of the specification between proposition rule, it is also possible to Carry out covering and check and difference inspection.When covering inspection, the specification represented by object-rule 802 will checked In specification that the specification compared represented by object-rule 803 is covered or by comparison other rule Specification represented by 803 and capped specification logs in the specification 805 of repetition.When difference checks, will Check in specification represented by object-rule 802 with the difference of the specification represented by comparison other rule 803 Specification logs in the specification 805 of repetition.

Fig. 9 is the flow chart of the step example representing rechecking.

Process shown below is to generate, by decision table, the CPU202 that auxiliary/checking device 201 is possessed The program performed in memorizer 203 realizes.Further, this program is described below various by carrying out The code of action is constituted.

CPU202 obtains any 2 lives by performing rechecking portion 106 from proposition rule storage unit 102 Topic rule, respectively as checking object-rule and comparison other rule.The inspection object-rule obtained and ratio Relatively object-rule logs in inspection object-rule 802 and the comparison other rule checking result storage unit 109 respectively Then (step 901) in 803.

The condition part of the condition checking object-rule that rechecking portion 106 obtains with reference to expression and expression ratio The condition part of the condition of relatively object-rule, it is determined that whether the condition part of both sides and is deposited.When condition part and when depositing, In the inspection result 804 checking result storage unit 109, log in " having repetition ", perform step 903.When Condition part not and when depositing, logs in " not repeating " in the inspection result 804 checking result storage unit 109, Unduplicated specification 806 logs in and checks object-rule and terminate to process.Can in the inspection of described compatibility To use SAT solver.Such as proposition rule 301 and the condition part of proposition rule 302 are also deposited, therefore In checking result 804, log in " having repetition ", perform step 903.(step 902).

Rechecking portion 106 check whether there is occur in comparison other rule does not appears in inspection right As the condition item in rule.Step 904 is performed when there being the condition item meeting described condition.When not having Step 906 is performed when meeting the condition item of described condition.Such as using proposition rule 301 as checking object Rule, during using proposition rule 302 as comparison other rule, the condition item of " volume is paid in insurance " meets Described condition, therefore performs step 904(step 903).

Rechecking portion 106 by that detect in step 903, occur in comparison other rule does not go out Check now that the condition item in object-rule is being examined with the value identical with the value occurred in comparison other rule The condition part looking into object-rule carries out logic product combination.The most in the case of the above-described example, will " " insurance Pay volume " be " more than 20,000 yen " " condition carry out logic product knot at the condition part of proposition rule 301 Close, worked as " insurance there was added nothing " and be and " adding " and " volume is paid in insurance " be " 20,000 yen with On " time, " subsidy " is the description of " having payment ".(step 904).

The specification 805 as repeating that describes generated in step 904 is logged in inspection by rechecking portion 106 In result storage unit 109 (step 905).

Rechecking portion 106 will check that object-rule logs in inspection result as the specification 805 repeated and preserves In portion 109, end processes (step 906).

Rechecking portion 106 by that detect in step 903, occur in comparison other rule does not go out Check now that the negative value of the value to occur in comparison other rule of the condition item in object-rule is checking The condition part of object-rule carries out logic product combination.The most in the case of the above-described example, by " " insurance is paid Na E " be not " more than 20,000 yen " " condition carry out logic product knot at the condition part of proposition rule 301 Close, worked as " insurance there was added nothing " be " adding " and " volume is paid in insurance " be not " 20,000 yen Time above ", " subsidy " is the description of " having payment ".(step 907).

The description generated in step 907 is logged in knot as unduplicated specification 806 by rechecking portion 106 Really in storage unit 109 (step 908).

Figure 10 is the example of Wen's logical operations figure that the result according to rechecking generates.

Scope 1001 represents the scope checking the specification represented by the i.e. proposition rule of object-rule 301.Scope 1002 scopes representing the specification represented by the comparison other i.e. proposition rule of rule 302.Scope 1003 represents The unduplicated specification of specification in inspection specification represented by object-rule and represented by comparison other rule Scope.Scope 1004 represents in the specification checked represented by object-rule and represented by comparison other rule The scope of specification that repeats of specification.

Figure 11 is the undefined inspection knot that undefined inspection portion 107 logs in checking result storage unit 109 The example of fruit.

The inspection result 1101 of undefined inspection is made up of undefined condition 1102.Undefined condition 1102 Represent the proposition rule preserved by proposition rule storage unit 102, the condition that result is not defined.

Such as, when proposition rule storage unit 109 preserves proposition rule 301,302 and 303, for " when " insurance there was added nothing " is " adding " ", " when " insurance there was added nothing " is " adding " " And the condition of " when " volume is paid in insurance " is " more than 20,000 yen " ", result be define complete.Separately On the one hand, for " " insurance there was added nothing " be " addition " and " volume is paid in insurance " be " 1 yen Above less than 20,000 yen " time " and " " insurance there was added nothing " is " addition " and " volume is paid in insurance " When being " 0 yen " " condition, result is undefined.Therefore, undefined condition 1102 log in this 2 Individual condition.

Figure 12 is the flow chart of the step example representing undefined inspection.

Process shown below is to generate, by decision table, the CPU202 that auxiliary/checking device 201 is possessed The program performed in memorizer 203 realizes.And this program is by the various actions carrying out following description Code constitute.

CPU202, by performing undefined inspection portion 107, obtains all of from proposition rule storage unit 102 Proposition rule (step 1201).

Undefined inspection portion 107, for each proposition rule obtained, generates the no of their condition part of expression Fixed description.But, when the negative in formation condition portion, about the arbitrary value of the X of any condition item X1, the description of unusable " " X " is not " x1 " ".In these cases, use condition item X's Value x_i beyond x1, x_i+1 ... x_j, use " " X " be " x_i " or " X " be " x_i+1 " ..., Or " X " is " x_j " " such description.Equally, in the description of logical formula form unusable not Equal sign " ≠ ".

It is assumed here that be endowed condition item A, B and result project C, take respectively a1 and a2, b1 and The value of b2, c1 and c2.At this moment, forSuch proposition rule, As the negative of its condition part, generate the description (step 1202) of " A=a2 ∨ B=b1 ".

Undefined inspection portion 107 would indicate that the description of the negative of the condition part in step 1202 generation is patrolled Collect long-pending combination (step 1203).

The description generated in step 1203 is deformed into long-pending and canonical form (step by undefined inspection portion 107 1204).

Undefined inspection portion 107 amasss the description with canonical form by each synthon by generate in step 1204 Sentence separates, and as undefined condition 1102, each synthesis clause is logged in inspection result storage unit 109 In (step 1205).

Figure 13 is that the restriction that restriction inspection portion 108 logs in checking result storage unit 109 checks result Example.

The inspection result 1301 that restriction checks is by checking object-rule 1302, restriction 1303, checking result 1304, the specification 1305 restricting object and the specification 1306 restricted outside object are constituted.

Check object-rule 1302 and restriction 1303 expression become restriction check object proposition rule and its Restriction.Check that result 1304 represents what the restriction of the restriction 1303 for checking object-rule 1302 checked Result.The specification 1305 of restriction object represents in checking the specification represented by object-rule 1302, restriction The specification of the restriction object of 1303.On the contrary, the specification 1306 outside restriction object represents inspection object-rule 1302 Specification in represented specification, outside the restriction object of restriction 1303.

For example it is assumed that as checking that object-rule 1302 provides proposition rule 302, as restriction 1303 And provide restriction 501.At this moment, restriction inspection portion 108 logs in " having object " as checking result 1304. Meanwhile, as the specification 1305 of restriction object, following specification is logged in, i.e. " when " insurance there was added nothing " Being " addition " and " volume is paid in insurance " when being " more than 20,000 yen ", " subsidy " is " not have Pay " ", as the specification 1306 outside restriction object, log in following specification, i.e. " when " insurance there was added Nothing " it not " addition " and " volume is paid in insurance " when being " more than 20,000 yen ", " subsidy " is " do not pay " ".

Figure 14 is the flow chart of the step example representing restriction inspection.

Process shown below is to generate, by decision table, the CPU202 that auxiliary/checking device 201 is possessed The program performed in memorizer 203 realizes.And this program is by the various actions carrying out following description Code constitute.

CPU202 obtains any 1 life by performing restriction inspection portion 108 from proposition rule storage unit 102 Topic rule is as checking object-rule.Obtain any 1 restriction from restriction storage unit 104 simultaneously.Obtain Check that object-rule and restriction log in inspection object-rule 1302 and the restriction checking storage unit 109 respectively In 1303 (step 1401).

Restriction inspection portion 108 is with reference to the inspection object-rule obtained and restriction, it is determined that check the bar of object-rule Whether the preceding paragraph of part portion and restriction and deposits.When and perform step 1403 when depositing.When not and when depositing, checking The inspection result 1304 of result storage unit 109 logs in " not having object ", the specification outside restriction object Log in 1306 and check object-rule and terminate to process.The inspection of described compatibility can use SAT solve Calculate device (step 1402).

Restriction inspection portion 108 judge to check the condition part of object-rule and restriction consequent whether and deposit.When also Step 1404 is performed when depositing.When not and perform step 1409 when depositing.The inspection of described compatibility can make Use SAT solver.Such as in the case of proposition rule 302 and restriction 501, condition part and preceding paragraph are also deposited, But condition part and consequent not and deposit, therefore perform step 1409.Additionally consider " " insurance there was added nothing " When being " addition ", " subsidy " is " having payment " " proposition rule 304 if, proposition rule 304 In the case of restriction 501, condition part and preceding paragraph are also deposited, condition part and consequent also and deposit, therefore perform step Rapid 1404(step 1403).

Restriction inspection portion 108 check whether there is occur in restriction consequent in and do not appear in inspection object Condition item in the condition part of rule.When there being the condition item meeting described condition, checking that result is protected Deposit login " having object " in the inspection result 1304 in portion 109, perform step 1405.When not meeting institute When stating the condition item of condition, in checking result 1304, log in " there is no object ", outside restriction object Specification 1306 logs in and checks object-rule and terminate to process.Such as proposition rule 304 and restriction 501 In the case of, the condition item of " volume is paid in insurance " meets described condition, therefore steps in checking result 1304 Record " having object ", performs step 1405(step 1404).

Restriction inspection portion 108 by that detect in step 1404, occur in restriction consequent in and do not go out Check now the negative value with the value of the consequent middle appearance of restriction of the condition item in the condition part of object-rule Logic product combination is carried out at the condition part checking object-rule.Such as proposition rule 304 and the feelings of restriction 501 Under condition, the condition of " " volume is paid in insurance " is not " 0 yen " " is entered at the condition part of proposition rule 301 Row logic product combine, obtain " when " insurance there was added nothing " be " addition " and " volume is paid in insurance " no When being " 0 yen ", " subsidy " is " having payment " " description (step 1405).

Restriction inspection portion 108 describes the specification 1305 as restriction object using generate in step 1405 Log in result storage unit 109 (step 1406).

Restriction inspection portion 108 by that detect in step 1404, occur in restriction consequent in and do not go out Check now that the condition item in the condition part of object-rule is with identical with the value of the consequent middle appearance of restriction Value carries out logic product combination at the condition part checking object-rule.Such as proposition rule 304 and restriction 501 In the case of, by the condition of " " volume is paid in insurance " is " 0 yen " " at the condition part of proposition rule 301 Carry out logic product combination, obtain " when " insurance there was added nothing " is " addition " and " volume is paid in insurance " When being " 0 yen ", " subsidy " is " having payment " " description (step 1407).

The specification 1306 described outside restriction object that restriction inspection portion 108 will generate in step 1407 Log in result storage unit 109 (step 1408).

Restriction inspection portion 108 check whether there is occurs in and does not appears in inspection object in the preceding paragraph of restriction Condition item in the condition part of rule.When there being the condition item meeting described condition, checking that result is protected Deposit login " having object " in the inspection result 1304 in portion 109, perform step 1411.When not meeting institute When stating the condition item of condition, in checking result 1304, log in " having object ", perform step 1410. Such as in the case of proposition rule 302 and restriction 501, the condition item of " insurance there was added nothing " meets institute State condition, therefore in checking result 1304, log in " having object ", perform step 1411(step 1409).

Restriction inspection portion 108 will check that the object-rule specification 1305 as restriction object logs in inspection knot Really in storage unit 109, end processes (step 1410).

Restriction inspection portion 108 by that detect in step 1409, occur in the preceding paragraph of restriction does not go out Check now that the condition item in the condition part of object-rule is with identical with the value occurred in the preceding paragraph of restriction Value carries out logic product combination at the condition part checking object-rule.Such as proposition rule 302 and restriction 501 In the case of, by the condition of " " insurance there was added nothing " is " addition " " in the condition of proposition rule 302 Portion carries out logic product combination, obtains " when " insurance there was added nothing " is " addition " and " volume is paid in insurance " When being " more than 20,000 yen ", " subsidy " is " do not have pay " " description.(step 1411).

The specification 1305 as restriction object that describes generated in step 1411 is stepped on by restriction inspection portion 108 Record is in result storage unit 109 (step 1412).

Restriction inspection portion 108 by that detect in step 1404, occur in the preceding paragraph of restriction does not go out Check now the negative value of the value to occur in the preceding paragraph of restriction of the condition item in the condition part of object-rule Logic product combination is carried out at the condition part checking object-rule.Such as proposition rule 302 and the feelings of restriction 501 Under condition, by the condition of " " insurance there was added nothing " is not " addition " " at the condition part of proposition rule 304 Carry out logic product combination, obtain " when " insurance there was added nothing " is not " addition " and " volume is paid in insurance " When being " more than 20,000 yen ", " subsidy " is " do not have pay " " description.(step 1413).

The specification 1306 described outside restriction object that restriction inspection portion 108 will generate in step 1413 Log in result storage unit 109 (step 1414).

Figure 15 is the example of the display strategy that strategy storage unit 111 is preserved.

Display strategy guide look 1501 is by strategy description 1502, strategy applicable elements 1503, display packing 1504 And invalidating attribute 1505 is constituted.

It is the strategy relevant with the method extracting display object-rule from inspection result that strategy describes 1502 Describe.Display object-rule determination section 114 according to explanation strategy describe the result of 1502 determine to show right As rule.Strategy applicable elements 1503 represents the condition for application strategy.The plan of not met applicable elements Slightly cannot function as showing that object-rule determination section 114 determines that the strategy of display object-rule is employed.Display Method 1504 represents the display object-rule that determines according to this strategy, display packing on decision table. Invalidating attribute 1505 represents that this strategy is the currently active or invalid.Even if meeting strategy applicable elements 1503, invalid strategy is also not applied.

The strategy of such as No.1 represents when checking that result storage unit 109 preserves the inspection result that contradiction checks When 601, it is determined as the specification of the specification 605 of contradiction showing object-rule, decision table is emphasized Display.
