DBRS Use Cases
The DBRS utility starts by reading some initial configuration information:
prompt > DBRSBuilder [-builderFile {path to dbrsbuilder.properties}] -stageDir {path to stageDir}
(if command-line arg -builderFile not present, default to look in current working directory)
prompt > DBRSBuilder running, connected to port 8884 ... Press <Return> to finish
dbrsbuilder.properties:
# builder properties
builder.port=8884
#builder.mode=production
builder.mode=test
builder.test.port=8885
# project properties
project.name=projectname
project.entities=employee, other entities ...
# database properties
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/db
db.user=user
db.pwd=password
db.platform=org.eclipse.persistence.platform.database.MySQLPlatform
logging.level=info
(if command-line arg -builderFile not present, default to look in current working directory)
prompt > DBRSBuilder running, connected to port 8884 ... Press <Return> to finish
dbrsbuilder.properties:
# builder properties
builder.port=8884
#builder.mode=production
builder.mode=test
builder.test.port=8885
# project properties
project.name=projectname
project.entities=employee, other entities ...
# database properties
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/db
db.user=user
db.pwd=password
db.platform=org.eclipse.persistence.platform.database.MySQLPlatform
logging.level=info
There are three scenarios to consider:
- the database contains the Project's entities: the typical scenario where the Project's entities are exposed via a RESTful CRUD application.
- the database does not contain the Project's entities: the so-called greenfield<i> scenario where the Project's entities do not yet exist on the database.
- meta-data describing the Project's entities is provided through an alternative mechanism: the scenario where the Project's entities are described via a JPA .orm file.
