Wirtschaftsinformatik Exam Review Flashcards

Vocabulary practice flashcards generated from Wirtschaftsinformatik exam reviews covering IT concepts, database principles, enterprise systems, data encodings, and machine learning fundamentals.

Knowledge (Wissen)

Information stored within a model combined with the capacity and ability to use it.

Binary Code

A base-2 numerical system used in computers because two distinct states can be distinguished most reliably by electronic components.

Data

Characters or symbols that are structured according to a defined syntax.

UDO-R Disks

Optical storage media that can only be written to once (WORM), preventing subsequent alterations and ensuring revision-safe (revisionssicher) document archiving.

64-Bit Processor

A central processing unit whose Arithmetic Logic Unit (ALU) and registers are 64 bits wide, enabling the simultaneous processing of 64 bits of data.

RFID Tag

An identification technology that allows contactless data exchange without direct line-of-sight, supports read/write capabilities, and stores larger data quantities than traditional barcodes.

QR Code

A two-dimensional matrix barcode capable of storing more data than a standard one-dimensional barcode, requiring image-processing technology to be read.

UTF-8 Encoding

A variable-width character encoding that uses one byte for standard ASCII characters and 2, 3, or 4 bytes to encode special characters and symbols.

Three Stages of Business Process Automation

The progression of daily business task execution by software: Stage 1) Manual processing despite computer use, Stage 2) Computer-supported processing, and Stage 3) Automated processing.

Administration System (Administrationssystem)

An operational software category designed to handle routine administrative business transactions, such as recording and booking incoming invoices.

Disposition System (Dispositionssystem)

An operational software system that supports short-term allocation and operational scheduling, such as personnel shift planning.

Cross-Functional System (Querschnittsystem)

Software that provides general support across multiple functional enterprise areas, including Groupware, Workflow Management Systems, and newsletter distribution tools.

Supervised Learning (Überwachtes Lernen)

A machine learning approach where training data is provided alongside target output values, allowing the system's output to be evaluated and corrected against known solutions.

Unsupervised Learning (Nicht überwachtes Lernen)

A machine learning approach where data lacks pre-assigned target solutions, requiring the system to evaluate outputs or discover patterns using an objective target function.

Controlling Cockpit

A management dashboard featuring concise visual summaries of key performance indicators (KPIs) and steering user attention using traffic-light color indicators.

Enterprise Resource Planning (ERP) System

An integrated business software suite operating on a centralized database foundation that can be individually customized to fit an organization's specific processes.

Production Planning System (PPS)

A core manufacturing software category containing specialized functionalities such as bill of materials (BOM) explosion (Stücklistenauflösung), material requirements planning, and schedule/capacity planning.

Merchandise Management System (Warenwirtschaftssystem)

An operational system managing inventory control, order tracking with status updates, and procurement processing for goods.

Application System Landscape Drivers

Reasons enterprises utilize multiple specialized application systems instead of a single monolithic ERP, including Best-of-Breed strategies, corporate mergers/acquisitions, and software lifespans outlasting technology cycles.
