Synthesis of work done (from SRR)



! Promotion" The CS Web server is up and available at http://debat.c-s.fr. The Web pages of

DEBAT are available online.

" A DEBAT workshop was held in ESTEC on the 19/02/2003. The main results ofthe first phase were presented (interviews and studies results, expectedrequirements) as well as the main foreseen features of DEBAT. Thepresentations are available on the Web site. ESA, CNES and CS participated tothe workshop.

! Software Requirements: starting from the User RequirementsDocument, the Software Requirements were produced following anadequate UML methodology (see SS/DEBAT/SRD 1.0).



! Selection Process: we made a first proposal of a coherent subset ofrequirements to be implemented in the second phase of DEBAT (seeSelection Process Methodology TN SS/DEBAT/SPM_TN 1.1). Thisfirst proposal is to be discussed/negotiated during the "End ofphase 1" meeting.

! Implementation, Diffusion and Validation Plan: this documentdescribes the logical plan of developments together with the meansnecessary to diffuse and validate the concepts that will beimplemented in DEBAT (see SS/DEBAT/IDVP 1.0)

14.15 � 14.30Product AssuranceReport[Maud Granet]


Introduction

! The aim of this presentation is to describe the quality actionsperformed from the System Requirements Review to the end of thePhase 1.

! Several quality actions were carried out :" Updating the Product Assurance Plan with Logiscope C++ coding rules,

" Setting an in-depth EAST code inventory,

" Controlling documentation for delivery,

" Providing support for the definition of the UML methodology for the SRD phase,

" Participating in progress meetings.


Let's focus on the in-depth EAST/OASIS code inventory

! The following table shows the code status of the currentEAST/OASIS tools.

" Controlling metrics

" Controlling rules# For each language of the EAST/OASIS code, a majority of the coding standard rules

were taken into account.

Methodology


Selection Process

! The URD defines the ideal DEBAT software

! Objective" Select the most relevant subset of the URD to be

included in the implementation phase of the DEBATsoftware.

! Mainly a trade-off between cost and added-value


Selection Process Methodology

! Requirements worded with « shall » and« should » and with priority levels (from 1 to 5)

! Methodology:" 1)Identify the DEBAT core requirements/functions (i.e. all the

requirements worded with shall)

" 2)Evaluate individually each requirement worded with 'should� forits inclusion/exclusion.

" 3)Iterate on the chosen subset (adjustment betweenbudget/requirements)

" 4)Define the implementation plan

6 DEBAT The EAST and DEDSLdescription files shouldhave a version number.

Y Low This feature will ease themanagement of description filesversions.

7 DEBAT The dates of creationand modification of theEAST and DEDSLdescription files shouldbe stored.

Y Low This feature will ease themanagement of the description filesversions.

10 DEBAT When loading EASTand DEDSL descriptionfiles in DEBAT, amessage should bedisplayed if thedescription was createdwith earlier versions ofthe EAST norm and/orthe DEBAT tools.

Y Low It will warn the users that they maybe using descriptions that are notcompatible with current version ofthe EAST norm and associatedDEBAT tools.

11 DEBAT When loading a datamodel in DEBAT, amessage should bedisplayed if the datamodel was created withearlier versions of thenorm and/or theDEBAT tools.

Y Low It will warn the users that the datamodel they are using may be notcompatible with the current versionof the EAST norm and associatedDEBAT tools.


15 DEBAT If the ascendingcompatibility is broken(due to major changesin the EAST norm orDEBAT tools), theDEBAT user should beable to transform theold format of the datamodel, EAST orDEDSL files into thenew one so as to keepthe ascendingcompatibility.

Y Could varyfrommoderate tohighdependingon thecompatibility issues.

The ascending compatibility ismandatory to insure the perennialityof the EAST and DEDSLdescription files.

As there are already someoperational projects using thetechnology, it is fundamentalto ensure the ascendingcompatibility.

18 DEBAT In case the EAST andDEDSL descriptionfiles are not compatiblewith the installedversions of the EASTnorm and DEBATtools, a list of theincompatible elements(i.e. their names andpaths in the EASTdescription) should begraphically rendered tousers.

N High Users will be able to know why andwhere their description files are notcompatible with the installedversion of the EAST norm andDEBAT tools.

This feature could be reallydifficult to implement as itimplies to follow anddocument with an adequateformalism all the evolutionsof the norms and of the tools.This feature could lead to ahuge amount of work andcould be really timeconsuming compared to thereal added-value.

110 EASTCORE Users should be able towrite generated datavalues in a socket.

Y Moderate This feature is useful for simulationpurposes since it enables users totest their real-time systems easilyand automatically by using realisticvalues.

The "real-time" generation iseasier to implement than the"real-time" reading, andseems necessary to add toDEBAT real capabilities inthe simulation applicationdomains.

111 EASTCORE Users should be able tocheck dataprogrammatically.

Y Moderate It will offer means to checkparticular elements against theirtypes, their default values or usinguser-specified values.

112 EASTCORE Users should be able tocheck a data productfield by field.

Y Low Users will be able to check anyspecific elements in the wholeEAST description.

113 EASTCORE The data checking APIshould propose differentlevel of checking for avalue (warning, error,fatal error).

Y Moderate Users will be able to refine thechecking to get only the errors theywant (if errors are detected).

114 EASTCORE The user should be ableto check data valuesusing computedconstraints.

Y Moderate Users will be able to compare oneelement's value with anothercomputed value.

There is a real added-valuewith this feature.

115 EASTCORE Through the API, theuser should be able tocheck data values usingexternal constraintspassed as methods'arguments.

Y Moderate It will leverage the checking sinceusers have more freedom to specifytheir constraints.

121 MODELLER Users should be able tointerface customapplications with theModellerfunctionalities.

159 MODELLER The DEBAT Modellertool should provide aclone functionality forusers to copy the modelview and open anotherview with this copy.

N High This feature would ease themanipulation of the model byallowing to display several views ofthe same data model (e.g. onecomplete view and one viewfocused and zoomed on a subset ofthe model).

This feature is costly (heavilydepends on the underlyingtechnology) and can lead toperformance problems(duplication of the GUIs).

160 MODELLER The DEBAT Modellertool should provide azoom functionality forusers to focus on aprecise part of themodel view.

Y Moderate/High

Users will only display the part ofthe model they are interested in. Itwill particularly useful to handlehuge data models.

There is a real need and a realadded-value. Note that thecost of this implementationheavily depends on theunderlying technology (XVTvs. Java) and is more costlywith XVT.

167 DPE Users should be able todisplay an EASTdescription content as adata byte flow view.

N High Users will have a different view oftheir models.

It is better to offer powerfultree structure views andnavigation capabilities. The"byte flow view" is inherentlya low-level view that is notreally interesting for the enduser. As there is a high costassociated to this feature, wepropose to discard it.

171 DPE Users should be able tohandle data cut inseveral packets.

N High The DPE will be able to handlelarge data files separated physicallyinto several data packets (providedthat an EAST description exists foreach packet and for the whole dataproduct).

It is a really specificapplication of the technology: the need has only beenexpressed by one user. Thismechanism could be built ontop of DEBAT for thisspecific use. As there is ahigh cost of integrating thisfeature in the DEBATenvironment and as the needis specific to a small subset ofusers, we propose not toinclude this feature.

9.30 � 10.00 Implementation,Validation, Diffusionplan presentation[Olivier Queyrut]

Implementation plan


[A-1] Presentation

! The implementation plan describes the logical plan defined for thedevelopment of the functional subset chosen in the previous phases(selection process [RD8] of the User Requirements [RD7]).


[A-1] Presentation

! All the DEBAT environmentwill rely on the existingEAST core

" The EAST core implementationshall be processed first or atleast the definition of themodifications � theirinterfaces � is a prerequisitefor the developments based onthese changes

" Most of the DEBAT tools willuse the Java API of the EASTcore


[A-2] Implementation of the DEBAT general features

! The WP 2312120 and WP 2312130 deal with features provided by all ofthe DEBAT tools. These work packages will be realised at the same time asthe implementation of the tools work packages (WP 2312500).

! The WP 2312110 shall be realised once all tools have been implemented

! The WP 2312140 and WP 2312150 can be realised at any time during theproject as they are completely independent from any other work package


[A-3] Integrated environment

! As the framework does not rely on any other tool or service, theimplementation of the integrated environment can thus be doneseparately and eventually at the same time as other work packages.


[A-4] Web interface � Local Web Site

! As the WP 2312312 and WP 2312313rely on the EAST core services (throughthe Java API), these work packages shallbe realised once the EAST coreimplementation has been finished (or atleast, its interface completely defined).

! The WP 2312312 shall be realizedbefore the WP 2312313 as theinterpretation of EAST descriptions isrequired in order to be able to processthe information contained in thecorresponding data products


[A-4] Web interface � Local Web Site

! The WP 2312320 shall be realised oncethe EAST core implementation has beenfinished (or at least, its interfacecompletely defined)

! The WP 2312321 shall be realisedbefore the WP 2312322 as the latterone relies on services implemented duringthe first one (i.e. EAST descriptions haveto be interpreted before being able toprocess data values)


[A-5] EAST core

! The general features mainly concern the improvements of the EAST coreperformances

! The next work packages are dealing with the implementation of newfeatures (e.g. support for calculation functions, support for default values,support for multi-file data, data checking capabilities enhancement, JavaAPI, etc)


[A-6] DEBAT Data Modeller

! Two schemas for the development of the Data Modeller:" To build the Data Modeller upon the existing OASIS tool

" To build the Data Modeller from scratch

Potential risks (mainly in terms of cost andschedule)

Reliable and flexible architecture

Powerful technologies (Java, XML)

Ease to add the new features

Reuse of developments between the tools

Tools homogeneity

Target platforms (linux, unix, windows)

Modellerfromscratch

Existing bugs and architecture weaknesses

XVT poor features

Linux platform not supported

Tools homogeneity

Benefits of the implementation alreadyperformed

Operationally validated

Modellerbased onOASIS

DrawbacksBenefits


[A-6] DEBAT Data Modeller upon OASIS


[A-6] DEBAT Data Modeller upon OASIS

! 1- Bugs correction and transformation of the existing IF format into XML

! 2- addition of all new syntactic and semantic features and their supports inthe Modeller graphical interface

! 3- updating/implementation of the file generation, documentationgeneration (in RTF, PDF and HTML) and search capabilities

! In parallel, the graphical interface is updated


[A-6] DEBAT Data Modeller from scratch


[A-6] DEBAT Data Modeller from scratch

! 1- Internal format in XML

! 2- Support for all the features of the EAST and DEDSL norms and creationof the type library.

! 3- Implementation of the search capabilities, the documentation generation(in RTF, PDF, HTML) and files generation (EAST/DEDSL, ADA, C/C++, Java)

! In parallel, the graphical interface is implemented


[A-7] DEBAT Data Producer & Editor

! The DPE is a completely new tool and will be built upon the Java API

! The main work packages are:" Data product generation: automatic/semi-automatic, degraded data generation, support for

calculation formulas

" Data storage: data writting on the standard output and in a socket

" Data search: support for wild card, combinaison of search criteria


[A-8] DEBAT Data Extractor & Querying

! The DEQ is a completely new tool and will be built upon the Java API

! The main work packages are:" XML-like queries

" Data extraction

" Batch processing


[A-9] DEBAT Utilities

! All these packages haveto be processed after themodifications of theEAST core since most ofthem (i.e. all except theEAST descriptionscomparison tool) rely onthis layer


[A-10] DEBAT Post-Processing Tools and DEBAT Distribution

! All these three work packages can berealized separately and eventually at thesame time.

! However, they require that the Java APIof the EAST core is available (or at leastits interface has been completelydefined).

! The main goal of the DEBAT distributionis to disseminate data packages (e.g.data alone, data along with itsdocumentation) to very end-users


[A-11] TM/TC & SCOS-2000

! Two prototypes will be realized:" Database import prototype: generation of the SCOS-2000 database import files relating to

the commanding and monitoring" TM/TC simulator prototype: simulation of the TM/TC processing chain of SCOS-2000

! 3 solutions have been identified for this WP:" [Solution 1] Simulator based on the DEBAT DPE or directly on the EAST Java API" [Solution 2] Simulator based on the ESOC TM/TC simulation solution (TMTT tool or TTSim)" [Solution 3] Simulator based on both the DEBAT DPE and on the CS flow manager PRISM


[A-11] TM/TC & SCOS-2000 � Simulation prototype

No assurance that this solutionwill be adopted by ESOC

No relationships with ESOCroadmap

Administrative issues: makerelationships between the twoprojects and merge theirobjectives

Technical issues: potentialdifficulties to make thetechnologies work together

Validation plan


[B-1] Current Applications validation

! WP 2511000: MERIS data product modellingand generation of the correspondingEAST/DEDSL description files

! WP 2512000: validation of the whole DEBATenvironment with the CRYOSAT data product.This data product is not modelled from scratchbut is based on the MERIS models to validatethe re-usability concept

! WP 2513000: validation of the data checkingwith the ASM-2 (ERS) data product. In thispackage, there is no need to model the dataproduct as the EAST description file andassociated data product already exist


[B-2] TM/TC & SCOS-2000 activities validation

! The two prototypes will be validated at factory premises with themeans provided by CS (version 2.3e of SCOS-2000 installed on theSUSE 7.3 Linux platform).


[B-2] TM/TC & SCOS-2000 activities validation! Three solutions have then been identified:

" Use of the Integral TM/TC packets format" Use of the Cryosat TM/TC packets format" Use of the Jason TM/TC packets format

The JASON format is notPUS compliant

Work to model with DEBATthe Integral TM/TC packets

Import files to bedelivered to CS by ESA

TM/TC description to bedelivered to CS by ESA

Work to model withDEBAT the IntegralTM/TC packets

Drawbacks

Benefits of the workperformed by another CSproject which created someof the import files manually

TM/TC description available

(partial) TM/TCdescriptions already donein DEBAT phase 1

Import files provided withSCOS-2000

Advantages

JASONCryosatIntegralTM/TCformat

Diffusion plan


[C-1] Diffusion plan

! DEBAT Web site: it will promote the DEBAT technologies and will enableusers to download all of the DEBAT tools

! CDRom package: it contains the whole DEBAT environment binaries (for alltargeted platforms: Windows, Unix, Linux) along with the associateddocumentation

! Demonstration kit: it contains demonstrations samples, success stories,quick introduction and quick start guide

! DEBAT brochure: it contains descriptions of the DEBAT tools and of theEAST/DEBAT benefits and domains of application
