Information systems for Swiss courts • 1st wave around 1980-85 : single applications – Tribunal fédéral, Genève, Zurich, Vaud • years 1990s : 2 vendors take the rest of the market – client-server (Windows) – moving towards 3-tiers architecture – each court as a closed, independent entity • 2005 : Geneva evaluates both vendors and decides not to take them – regression in functionalities – complexity of data migration (different models) – global switch very risky DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 10

History and future • 1985: information system (Cobol + "All-in-1" office suite) • 2002: 1st Perl applications (statistics, Web reporting) • 2004: 1st major business application in Perl (judgements archive) • 2005: vendor analysis, decision to rewrite the business application • 2006: prototype "proof-of-concept" in Perl/Catalyst • 2007: call for tenders • 2008: development, stepwise introduction • 2010: parameterizing new laws • 2011: electronic data exchange • 2013: database migration • 2014: office migration DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 13

Goals • replace old applications, obsolete – office (DEC All-in-1) – business application (VMS / Cobol / DBMS Basis+) • groupware • electronic data exchange, open towards external partners • adapt to important changes in law and organization DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 14

Principles • Stepwise migration – functionality chunks – old and new application live side-by-side on same database • Web Application – inter-application links – desktop/office integration • Optimize user efficiency – special care for keyboard navigation – DHTML / Ajax • Sophisticated parameterization example – 1 single app for various needs of 37 courts DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 15

Resources Other projects Etat GE • Budget (pluriannual) integrated – i-JUGE : CHF 7'650'000 accounting : 100 MCHF – Justice 2010 : CHF 4'140'000 human resources : 60 MCHF • People – Strategic management : 8p. – Operational management : 5p. – Help desk, support, teaching : 6p. – Analysis : 3p. – Development & maintenance : 7p. – Parameterizing, document production, Cobol maintenance : 2p. – DBA, systems, exploitation : 5p.

Département Office Technical aspects DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 1

Why Perl ? • positive experiences on former, less critical applications • expressive power, concision – ( but not cryptic ! ) • productivity through available components (CPAN) – Template – Catalyst • modularity and abstraction mechanisms – multiparadigms ( imperative, object-oriented, functional ) • dynamic language Old app – no compilation phase • core in Cobol – dynamic loading of components • scripts in "PRC" – dynamic class / method creation DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 18

Département Office Conclusions DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 1

Positive • Perl – never any technological problem – code clear and concise (mostly) – good suite of tools – productivity – internal resistance disappeared DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 23

Negative • sometimes hard to recruit – (but not impossible) – some consultants refused to do any Perl ("would stain their CV" !) – no Perl teaching in schools and universities • heavy parameterization hard to test – combinatorics, many possible cases – complex data sets • technical problems – still some install difficulties on Win32 – no native Perl driver for our DBMS; JDBC too slow DIRECTION DES SYSTÈMES D'INFORMATION (DSI) Gestion des procédures judiciaires 01.08.2009 - Page 24
