OCR = Optical Character Recognition

= 'optisk genkendelse af tegn' - benyttes i specielle programmer, som ofte leveres som tilbehør til en scanner. En trykt tekst scannes d.v.s omdannes til computerdata, som i første omgang blot er et billede med lys baggrund og en masse sorte billedpunkter, som vi kan genkende som tekst. Men hvis teksten skal kunne redigeres - som tekst - på computeren, skal billedet tolkes af et OCR-program, som analyserer mønstrene i billedet og sammenligner dem med kendte mønstre for alle alfabetets tegn. Programmet konstruerer så et tekstdokument med resultatet af tolkningen. Selv gode OCR-programmer begår ofte mange fejl, som skal rettes manuelt - men dette arbejde er typisk meget mindre end at indskrive hele dokumentet.

ODBC = Open Database Connectivity

En international standard for kommunikation med databaser (fx Oracle, SQL Server, Navision).
ODBC er en API, som giver programmer SQL-adgang til databaser.
 

Allows a front-end product such as Visual Basic to talk correctly to any popular back-end database.
A standard or open API for accessing a database. By using ODBC statements in a program, you can access files in a number of different databases, including Access, dBase, Excel, and Text. A separate module or driver is needed for each database to be accessed.
ODBC is based on the Open Group standard SQL Call-Level Interface. It allows programs to use SQL requests to access databases without knowing the proprietary interfaces to the databases. ODBC handles the SQL request and converts it into a request the individual database system understands.
ODBC was created by the SQL Access Group and released in September, 1992. Microsoft Windows was the first to provide an ODBC product, but versions now exist for UNIX, OS/2, and Macintosh platforms.
In the newer distributed object architecture called CORBA, the Persistent Object Service (POS) is a superset of both the Call-Level Interface and ODBC. When writing programs in Java and using the JDBC API, you can use a product that includes a JDBC-ODBC "bridge" program to reach ODBC-accessible databases.

OLAP = On-Line Analytical Processing

En "OLAP kube" udgør ofte en delmængde af de analysedata, der er lagret i virksomhedens Data Warehouse. OLAP kuber er normalt funktionsorienterede, dvs. rettet mod bestemte analysefunktioner i virksomheden, fx finansanalyse, salgs- og købsanalyse eller budgettering.
 
[TechWeb]: Decision support software that allows the user to quickly analyze information that has been summarized into multidimensional views and hierarchies. For example, OLAP tools are used to perform trend analysis on sales and financial information. They can enable users to drill down into masses of sales statistics in order to isolate the products that are the most volatile.

Traditional OLAP products, also known as Multidimensional OLAP, or MOLAP, summarize transactions into multidimensional views ahead of time. User queries on these types of databases are extremely fast, because the consolidation has already been done. OLAP places the data into a cube structure that can be rotated by the user, which is particularly suited for financial summaries.

Ophavsret = Copyright

Lovgivning, som beskytter mod 'uberettiget' kopiering af tekst, billede, program, musik eller andet materiale, der kan kopieres. Ejeren af 'værket' sikres herved eneretten til økonomisk udnyttelse af materialet.

OS/2

Et operativsystem, som blev startet i et samarbejde mellem Microsoft og IBM - OS/2 skulle afløse DOS. Da Microsoft gik egne veje og udviklede Windows, fortsatte IBM med udviklingen af OS/2, som dog ikke kunne klare konkurrencen med Windows - IBM har derfor stoppet udviklingen af OS/2, som dog fortsat understøttes af IBM. Den sidste udgave var 'OS/2 Warp 4' med Netscape-baseret browser. Salget af denne udgave stoppede 31. januar 2001.

OSA = Office Start Application

The OSA is a program (C:\Programmer\Microsoft Office\Office\OSA.EXE) that improves the performance of Office 97 programs.
The Office 97 Setup program places a shortcut to the OSA in the Windows Start folder ( Microsoft Office-start).
Use ctrl-alt-del to bring up the Task-List to see if Osa is running.

 
The OSA does the following:

• Initializes Automation
• Initializes some of the common fonts installed by Microsoft Office 97
• Handles certain commands (New Office Document, Open Office Document, Help, and Screen Saver) on the Start menu and on the Office Shortcut Bar
• Displays Microsoft Outlook notifications when the Office Assistant is available

Outlook

Microsofts professionelle e-mail program (mail kilent), som også indeholder kalender, adresselister, mulighed for aftale af møder og mange andre faciliteter til håndtering af 'personlig information'.
 

Microsoft's most powerful e-mail client integrates e-mail with personal information management and groupware features. It offers calendars, journals, and schedules; a battalion of contact management tools; and the ability to create personal folders and subfolders. If your office runs Microsoft's Exchange Server, employees can use Outlook to share contacts and calendars. You can automate e-mail retrieval, tag messages with notes about follow-up action, and drag and drop Microsoft Office files into e-mail messages.

 

Outlook Express
'Gratis' e-mail program som følger med Windows 98, Windows 2000 og alle udgaver af Internet Explorer siden version 4. Outlook Express er en mindre udgave af Outlook - bl.a. er der ingen kalender.
 

This e-mail program is built into Internet Explorer 4.0 and Windows 98. Outlook Express is the successor to Internet Mail and News, which is found in earlier versions of Microsoft's Internet Explorer. Outlook Express supports HTML-formatted mail and offers a few nifty features such as the ability to integrate e-mail with Usenet news and the ability to search big Internet "white pages." It can filter e-mail (useful for automatically deleting spam), and gather messages from multiple ISPs.
