@SYMTestCaseID			SYSLIB-DBMS-CT-3407
@SYMTestCaseDesc		Test for defect DEF103023 - DBMS requires ReadDeviceData and WriteDeviceData capability to read from the db.
 						The current test application has no capabilities at all.
 						"C:TestDB.DB" database is a secure shared database with:
 							- no "READ" polycy (no restrictions apply to the database read operations);
 							- "WRITE" policy with "WriteUserData" capability defined;
 							- "SCHEMA" policy with "NetworkServices" capability defined;
 							- table C has no defined securoty policy, so the database security policy will be used;
 						The current test application should be able to:
 							- begin/commit/rollback a "read-only" transaction;
 						But should fail if:
 							- begin a transaction and try to modify the database within the transaction;
 						This test function asserts the test cases described above.
