Great Question! There are so many tools available, one of the toughest things for anyone new to it is to to decide where to begin. A good start would be to try Quantum GIS. Depending on your interests, I would also recommend looking at GRASS GIS, MapServer and PostGIS. These projects have active user communities and recent releases... generally meaning they're well maintained and going somewhere.

Patric,

Congratulations on completing the course. Can you provide a list of open source tools you would recommend?

Thanks,

Paul

Comment on Using Groovy to Create Sample Data in XML format for AppFuse by Sebastian Gärtner

Hi,
here is another short one, without the cost of fetching MetaData
…
def sql = Sql.newInstance(URL,USER,PWD, DRIVER)
def tablename=”any_table”;
table=sql.rows(“select * from “+tablename)
xml = new groovy.xml.MarkupBuilder()
xml.”${tablename}”(){
for (row in table){
Row(){
for (field in row){
“${field.key}”(field.value)
}
}
}
}

pretty useful way to dump data. I wanted to do something similar so I altered what you had and made the following:

def db = Sql.newInstance(databaseUrl, databaseUsername, databasePassword, databaseDriver)
def file = new File(“output.xml”)
def tables = ["tableA", "tableB"]
def xml = new MarkupBuilder(file.newWriter())
xml.data {
tables.each { table ->
xml.table(name:”${table}”) {
db.eachRow(“select * from ${table}”.toString()) { row ->
def data = [:]
def metaData = row.getMetaData()
for (i in 0.. def name = metaData.getColumnLabel(i+1)
def value = row[i]
data.”${name}” = value
}
xml.row(data)
}
}
}
}

Pretty much the same thing as yours except I wanted to dump data for multiple tables and I merged the metadata code with iterating the rows.

I actually played around with using DbUnit’s export feature, as I thought that would be the easy way to do it. I first had some issues in that the exported XML contained the schema’s from which I was migrating data, though I ultimately was able to get around that, and then I found my exported xml was not nearly as pretty (I’m picky). Writing the Groovy script probably took less time than learning more about DbUnit to fix my issues. Groovy is a no-brainer language to pick up for a Java developer, and it rocks as a quick, get-it-done, scripting language for tasks such as this.

You can also use DbUnit’s “export” feature to export a database’s tables to XML format. I’ve used this in the past to export a prod database to dev to reproduce an issue related to bad data.

You can do the loops in a much better way in groovy… look it up..

If you want to skip the reloading of tables, use this switch at the command line when running “mvn”

-Dmaven.test.skip=true
