Comparing Objectivity and Versant: Database Creation

• Create new federated database

oonewfd -lockserver pcbunn -fdfilepath f:\stars\stars.fdb starsdb

• Imbue it with the stars “schema”

ooddlx stars.ddl starsdb

• Compile the source file

cl.exe … stars.cpp

• Compile the file created by “ooddlx”

cl.exe … stars_ddl.cpp

• Link the application

link.exe … stars.obj stars_ddl.obj …

• Make new group database placeholders

makedb -g starsdb1

makedb -g starsdb2

• Create the group database files

createdb starsdb1

createdb starsdb2

• Create the “schema” .sch from the .imp file

schcomp -I. -I\versant\5_0_7\NT\h schema.imp

• Imbue the databases with the schema

sch2db -D starsdb1 -y schema.sch

sch2db -D starsdb2 -y schema.sch

• Compile the application and methods files

cl.exe … stars.cpp

cl.exe … methods.cpp

• Compile the file created by “schcomp”

cl.exe … schema.cxx

• Link the application

link.exe … stars.obj methods.obj schema.obj ...
