Data Awareness
See Data Literacy
Database
Refers to a system for electronic data management. Data is collected and stored here.
Data Driven Management
Data-driven management means making business decisions based on data and facts.
Data Engineer
A data engineer is an important job role in the data environment. Data engineers are primarily tasked with installing and maintaining data pipelines. Data pipelines can be understood here as the automated transfer and processing of data. Data engineers ensure that data quality remains consistently high and that data processing is performant.
Datafication
Describes the digitization of everyday activities and areas of life and the associated generation of data.
Data lake
A data lake is a repository where data can be stored in its original form. Unlike a data warehouse, the data stored in the data lake is not ready to be analyzed, but unsorted. On the one hand, this allows greater flexibility when handling this data, but on the other hand, the hurdle is higher for users. This makes the data lake particularly useful for the requirements of data scientists and data analysts.
Data Literacy
Data literacy can be translated as basic data competence. This describes the ability to assess and deal with data. This includes understanding why and how data is collected, what value it adds, and how its analysis works.
Data management
Data management (also known as data administration) encompasses all aspects that form the basis for successful data strategies. The goal of data management is to optimally prepare and make data available for processing.
Data Science
Data science combines scientific and statistical applications for extracting knowledge from data. Statistics, higher mathematics, programming and artificial intelligence methods are used.
Data Scientist
Data scientist is one of the most sought-after professions and job roles of the decade. Data scientists use scientific methods, as well as machine learning and artificial intelligence methods, to work on complex problems involving data or to develop data products. In addition to programming, they also use higher mathematics and statistics methods.
Data, structured and unstructured
Digital information (data) usually has different structures. A distinction is made between structured, semi-structured and unstructured data. Depending on what form it is available in, it is simpler, or less complex to prepare the data for processing.
Data Thinking
Data thinking combines data science and design thinking methods to successfully develop data products and data strategies. Data Thinking considers and solves problems by taking the user’s point of view.
Data Warehouse
A data warehouse is a central database optimized for data analysis. The data is prepared and follows a defined structure. The structure of the data warehouse simplifies standardized queries, e.g. for creating reports. Due to the high degree of preparation and standardization of the data, there is a lower threshold for use, but the possible applications are less flexible than those of a data lake.
Data visualization
Data visualization is the graphical representation of data with the aim of getting a quick insight into the information resulting from the data and communicating it.
Deep Learning
Deep dearning is one of the most advanced and complex approaches to Machine Learning. Called neural networks, they consist of algorithms inspired by the structure and function of the brain, but significantly beyond human capabilities. Deep learning models can make their own predictions completely independent of humans. To do this, they analyze data following a logical structure to make the most likely prediction from the results.
Design thinking
Design thinking is used to create solutions to problems and approaches to new ideas. It is an approach that aims to create solutions for user-friendly applications.
Digitalization
This is the transformation of analog processes into digital ones. This also fulfills the added value of creating digital data in this process, which facilitates collection and processing
Digitization
Digitization is the transformation of analog content into digital content.
K
Keras
Keras is an open source library. Keras is used to perform rapid implementation of neural networks. Accordingly, Keras is often an important building block in deep learning applications.
Key Performance Indicator (KPI)
KPI is an abbreviation for key performance indicator and refers to key figures that are defined to measure the success of an activity or the performance of a person or a department. They are used in corporate processes to make performance measurable and evaluate it.
M
Machine Learning
Machine learning is a field of artificial intelligence that aims to enable computers to automatically draw data from their environment and make assessments in order to make better decisions. In doing so, the algorithm learns rules from data on its own. How well an artificial intelligence learns depends on the quality and quantity of the data it is provided with to learn from. (Principle of “garbage in, garbage out”).
Matplotlib
Matplotlib is a library of the Python programming language. It is particularly suitable for visualizing data.
O
OOP – Object-oriented programming
OOP is a programming style that is well suited, e.g., for the production of software that is both complex and needs to be continuously updated. The code is organized around or by so-called objects, which are put in relation to each other. Everything that exists within a program is its own object, containing its unique attributes and behavior. Object-oriented programming is therefore a particularly efficient approach, as the program code can be reused and scaled.
P
Pandas
Pandas is a program library of the Python programming language, which enables the data to be cleaned, managed and analysed. DataFrames are the main feature of Pandas, which represent data in a table made up of columns and rows.
Predictive Maintenance
Predictive maintenance is a maintenance process to minimize the “downtime” of machines and manufacturing equipment. It aims to optimize maintenance cycles by calculating the probability of system failures. Maintenance can be better planned and predictable failures can be prevented. For this purpose, predictive maintenance collects data about the machine being monitored in real time in order to detect deviations at an early stage.
Python
Python is an open-source programming language that can be used to develop software applications. Python is easy to learn compared to other programming languages and is therefore very popular. Python provides access to many libraries that are especially popular in the data environment, such as Pandas, Matplotlib, and Keras.
