If you are new to oracle lite i would suggest you just use the MDK or wtgpack to create your first application as it guides you through more, before tackling the APIs (which need more understanding of the process).
The normal purpose of using oracle lite is to create a database on a client evice that is synchronised with the server database. In order to do this you will go through the following steps
1) define an 'application' (sometimes called a 'publication') - the name of this will be the name of the client database. basic things you do is give it a name and a destination platform (WIN32, PPC2003 etc.)
2) for each table you want in the client database, you define a 'publication item' (basically a snapshot definition). This needs an internal name (MDK/wtgpack creates these automatically in the format WTGPI_nnnnn), the base schema containg the table, the name of the table, the refresh mode (complete or fast), basic conflict resolution (client wins or server wins), dml flag (only if you want read only items), a priority order (the order of inserts if there are multiiple table to deal with parent/child relationships) and a SQL statement
The basic for the SQL statement is
select * from schema.table - this selects all data
if you want to restrict the data sent, then this can be either fixed for all users
select * from schema.table where id between 1000 and 2000
or using a bind variable
select * from schema.table where assigned_user=:username
3) once you have the application and publication items defined you publish it to the mobile server
4) in the mobile server manager you will now be able to see the application you have defined, and all of the meta data related to the publication items
5) you now create a user
6) after creating the user, you go to access and link them to the application, and if you used any bind variables go into data subsetting and set the value for that user
7) next on the client device you need to install the oracle lite client - easiest done by going into IE and the link <mobileserver>/webtogo/setup and follow the instructions
8) next on the client run msync, specify the user, password and server url and the database should download
