Contents
Sanger Pathogen Sequencing Unit (PSU)
- GeneDB is the organism data and annotation database for the Pathogen Sequencing Unit (PSU) at the Sanger Institute, UK
- Contains 37 organisms, which is expected to grow to 62
- Artemis is an annotation/DNA graphical interface
- PSU is currently migrating to chado schema
- We've implemented a common interface with the two leading open source frameworks: Hibernate and iBatis
Technical - Connections
Connections for the Hibernate engine are configured in the Spring configuration file
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="org.postgresql.Driver" /> <property name="url" value="jdbc:postgresql://holly.sanger.ac.uk:5432/chado" /> <property name="username" value="DELIBERATELY_BOGUS_NAME"/> <property name="password" value="WIBBLE" /> </bean>
- Uses a connection pool
- Connection to the database is specified graphically, so the iBatis configuration file has variables for the location:
<property name="JDBC.Driver" value="org.postgresql.Driver"/> <property name="JDBC.ConnectionURL” value="jdbc:postgresql://${chado}"/> <property name="JDBC.Username" value="${username}"/> <property name="JDBC.Password" value="${password}"/>
- provide database location, username & password
- select from scrollable list of feature with residues (organisms in separate Postgres schemas) what to open in Artemis
Technical - Code Generation
- The shared interface and hibernate implementation were originally generated
- There’s no explicit code generation (although the Spring and Hibernate runtimes may use them behinds the scenes)
Technical - Transactions
- Transactions are fully supported
Problems 1, 2, & 3
Creating a gene
genes[0] = new Feature(ORG, GENE, "xfile", false, false, now, now); genes[0].setSeqLen(1029); sequenceDao.persist(genes[0]); FeatureLoc loc = new FeatureLoc(SOURCE_FEATURE, genes[0], 13691, false, 14720, false, (short)1, 0, 0 ,0); sequenceDao.persist(loc); addFeatureProp(genes[0], "description", "A test gene for GMOD meeting"); addSynonymsToFeature(genes[0], "mulder", "scully"); createExon("exon1", genes[0], 13691, 13767, now, 0); createExon("exon2", genes[0], 14687, 14720, now, 1);
Retrieve a gene
Feature f = sequenceDao.getFeatureByUniqueName("xfile"); displayGene(f);
Update a gene
genes[0].setUniqueName("x-file"); sequenceDao.merge(genes[0]);
private Feature createExon(String name, Feature gene, int min, int max, Timestamp now, int rank) { Feature exon = new Feature(ORG, EXON, name, false, false, now, now); exon.setSeqLen(max-min); sequenceDao.persist(exon); FeatureLoc loc = new FeatureLoc(SOURCE_FEATURE, exon, min, false, max, false, (short)1, 0, 0 ,0); sequenceDao.persist(loc); return exon; }
Demo – Sample Problem
Simple web page to demonstrate displaying a basic feature
