2. Drivere ODBC
Open Database Connectivity (ODBC) reprezintă o interfaţă
standard care permite unei aplicaţii să acceseze date din
surse diferite: Oracle, MS SQL Server, DB2, Informix, MS
Access, dBase ş.a. Iniţiativa ODBC a aparţinut companiei
Microsoft, având acceptul şi concursul firmelor de soft care
produc servere BD.
Interfaţa ODBC defineşte:
• o bibliotecă de apeluri de funcţii care permit unei aplicaţii
să se conecteze la o sursă de date, să execute fraze SQL şi
să primească rezultatele acestora;
• o modalitate standard de conectare la o sursă (BD) de date
externă;
• o modalitate standard de reprezentare a tipurilor de date.
• Mai trebuie menţionat că această interfaţă mai permite şi
recepţionarea, tot printr-un mecanism standardizat, a
erorilor generate de motoarele diferitelor servere de baze de
date care gestionează BD sursă.
3. MDAC
The Microsoft Data Access Components (MDAC) are a standard database interface
for Windows. MDAC is already included as part of Windows 98, Windows 2000, Windows ME,
and Windows XP. Some early Windows 98 OEM systems shipped without MDAC,
however. MDAC
is also already installed on your system if you have Internet Explorer 5.0 (or higher) or
Microsoft Office. MDAC is FREE and is fully supported by Microsoft on all versions of Windows.
Zugg Software applications require MDAC version 2.5 or higher, with MDAC
2.8 recommended. Windows 2000 ships with version 2.5, and Windows XP ships with version
2.7. If you have a Windows 95, 98 or Windows NT system, installing version 2.5 or higher is
required. While older versions of MDAC may work, they may be very slow or have memory
leaks. For best performance, you should install MDAC 2.8 on all versions of Windows.
If your system does not already have MDAC installed, you need to download it and install it
according to the instructions given here. There is no way to run the application without
MDAC. To check to see what version of MDAC is already installed on your system, use the MDAC
Checker program described below.
Microsoft has thoroughly tested MDAC. However, since this software becomes part of your
operating system, there might be some very old systems that have trouble with MDAC. Zugg
Software is not responsible for any damage to your system or data loss caused by
MDAC. Because MDAC is system software, there is no way to uninstall MDAC without
reformatting your hard disk and reinstalling Windows. However, as scary as that sounds,
problems with MDAC are very rare. If you are running a database server on your computer,
such as SQL Server, Oracle, Sybase, etc, consult with your system administrator
5. • trebuie apelat administratorul surselor de date
ODBC (din Control Panel - ODBC Data Source). Din
cadrul de pagină (User/System/File)DataSourceName
6. • se alege butonul Add care lansează fereastra de dialog
Add Data Source.
7. • Din lista de drivere ODBC se alege
Oracle ODBC Driver
8. • completarea informaţiilor cerute în fereastra
de dialog Oracle8 ODBC Setup( Data Source
Name, UserId şi Service Name)
9. • După selectarea butonului OK din ultima fereastră de
dialog, numele sursei de date se va regăsi printre
celelalte surse de date disponibile pe respectiva
maşină.
