Datenmodellierung und Datenbankentwurf: Ein Vergleich aktueller Methoden

Der Autor betrachtet alle etablierten Methoden der Datenmodellierung, angefangen bei der Semantischen Datenmodellierung ERM (Entity-Relationship-Modellierung), ihrer Präzisierung als SERM (Strukturierte ERM) und ihrer Konkretisierung in den Datenbanken der SAP-Unternehmensmodelle als SAP SERM bis zur relationalen Datenmodellierung, die zum konkreten Datenbankentwurf führt.

SQL example to fetch employee names, salaries, and commissions from the EMP table. * PROGRAM SAMPLE11 EXEC SQL BEGIN DECLARE SECTION Declare the cursor variable.

You can also pass a character string to the precompiler. However, the string cannot contain trailing blanks. For example, the following CONNECT statement will fail: * Declare host variables. EXEC SQL BEGIN DECLARE SECTION ... CHARACTER*5 ORAID EXEC SQL END DECLARE SECTION ORAID = ’/ ’ EXEC SQL CONNECT :ORAID For more information about operating system authentication, see the Oracle7 Server Administrator’s Guide. 1 – 44 Pro*FORTRAN Supplement to the Oracle Precompilers Guide Concurrent Logons Your application can use SQL*Net to access any combination of remote and local databases concurrently or make multiple connections to the same database.

You declare a Pro*FORTRAN cursor variable using the SQLCURSOR pseudotype. For example: EXEC SQL BEGIN DECLARE SECTION ... SQLCURSOR CURVAR ... EXEC SQL END DECLARE SECTION A SQLCURSOR variable is implemented using a FORTRAN INTEGER*4 array in the code that Pro*FORTRAN generates. A cursor variable is just like any other Pro*FORTRAN host variable. Writing a Pro*FORTRAN Program 1 – 35 Allocating a Cursor Variable Before you can OPEN or FETCH a cursor variable, you must allocate it using the Pro*FORTRAN ALLOCATE command.
