Perl DBI API Reference
H Perl DBI API Reference This appendix describes the Perl DBI application programming interface. The API consists of a set of methods and attributes for communicating with database servers and accessing databases from Perl scripts. The appendix also describes MySQL-specific extensions to DBI provided by DBD::mysql, the MySQL database driver. I assume here a minimum version of DBI 1.50, although most of the material applies to earlier versions as well. DBI 1.50 requires at least Perl 5.6.0 (with 5.6.1 preferred). As of DBI 1.611, the minimum Perl version is 5.8.1. I also assume a minimum version of DBD::mysql 4.00. To determine your versions of DBI and DBD::mysql (assuming that they are installed), run this program: #!/usr/bin/perl # dbi-version.pl - display DBI and DBD::mysql versions use DBI; print "DBI::VERSION: $DBI::VERSION\n"; use DBD::mysql; print "DBD::mysql::VERSION: $DBD::mysql::VERSION\n"; If you need to install the DBI software, see Appendix A , “Software Required to Use This Book.” Some DBI methods and attributes are not discussed here, either because they do not apply to MySQL or because they are experimental methods that may change as they are developed or may even be dropped. Some MySQL-specific DBD methods are not discussed because they are obsolete. For more information about new or obsolete methods, see the DBI or DBD::mysql documentation, available at http://dbi.perl.org or by running the following commands: % perldoc DBI % perldoc DBI::FAQ % perldoc DBD::mysql The examples in this appendix are only brief code fragments. -

It's also a good language for many system management tasks. The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal). -

Tiketöintijärjestelmän Käyttöönotto
TIKETÖINTIJÄRJESTELMÄN KÄYTTÖÖNOTTO LAHDEN AMMATTIKORKEAKOULU Tekniikan ala Tietotekniikka Tietoliikennetekniikka Opinnäytetyö Kevät 2013 Janne Nummela Lahden ammattikorkeakoulu Tietotekniikan koulutusohjelma NUMMELA, JANNE: Tiketöintijärjestelmän käyttöönotto Tietoliikennetekniikan opinnäytetyö, 41 sivua Kevät 2013 TIIVISTELMÄ Tämän opinnäytetyön tavoitteena oli kartoittaa, valita ja asentaa avoimeen lähdekoodiin perustuva palvelupyyntöjen kirjausjärjestelmä eli tiketöintipalvelu. Tämän lisäksi työssä alustettiin ITIL-viitekehyksen käyttöönottoa yrityksessä. Työn toimeksiantajana oli LahtiNetwork Oy, joka on lahtelainen ict-palveluja tarjoava yritys. Työssä pyrittiin ottamaan huomioon LahtiNetworkin tarpeet ohjelmiston suhteen. Aikaisemmin yrityksen käytössä ei ollut tiketöintijärjestelmää, joten tulleita palvelupyyntöjä ei kirjattu järjestelmällisesti. Tiketöintijärjestelmä mahdollistaa palvelupyyntöjen järjestelmällisen kirjaamisen ja hallinnan. Tiketöintijärjestelmä tarjoaa palvelupyyntöjen vastaanotto-, kirjaus-, hallinta- ja muokkauspalvelut. Tiketöintijärjestelmä koostuu palvelimesta ja siihen asennettavasta ohjelmistosta. Ohjelmistot jakautuvat ilmaisiin avoimen lähdekoodin ohjelmiin ja maksullisiin ohjelmistoihin. Ohjelmia löytyy markkinoilta lukuisia aina pienestä pelkästään tiketöintiin perustuvasta ohjelmasta isoon koko help desk -prosessin käsittävään ohjelmaan. Yhteistä kaikilla ohjelmilla on kuitenkin se, että ydinajatus on tallentaa ja seurata järjestelmään tullutta palvelupyyntöä. Palvelupyyntö voi olla virheilmoitus, -
