An OLAP cube (Online Analytical Processing) or data cube, also known as a cube operator, is a term commonly used in data warehouse theory to represent data logically. The data is arranged as elements of a multidimensional cube. The dimensions of the cube describe the data and allow easy access. Data can be selected across one or more axes of the cube. The term OLAP (Online Analytical Processing) … [Read more...]
What is Data Virtualization?
The term data virtualization refers to certain approaches in the field of data management as a subset of data integration. These make it possible to query and manipulate data from source systems without the need for the querying system to be aware of its detailed technical information – such as the structure of the data source or the physical storage location. Data virtualization can be seen as … [Read more...]

Lossy Compression vs Lossless Compression
In our earlier article, we have described the basic details about data compression. Also, we have pointed out that lossless compression is when the compressed data can be used to extract exactly the original data. This is necessary, for example, when compressing executable program files. Examples are: Images: RAW, BMP, PNG General: ZIP Audio: WAV, FLAC In the case of lossy … [Read more...]
What is Data Compression
Data compression is a process in which the amount of digital data is condensed or reduced. This reduces the amount of storage space required and reduces the data transfer time. In telecommunications, the compression of messages from a source by a sender is called source encoding. Basically, data compression attempts to remove redundant information. To do this, the data is converted into a … [Read more...]
Basic Details of MP3 Audio Format
MP3 is actually MPEG-1 Audio Layer III or MPEG-2 Audio Layer III. It is a method of lossy compression of digitally stored audio data. MP3 makes use of psychoacoustics with the aim of storing only perceptible parts of the signal for humans. As a result, with barely reduced perceived audio quality, a strong reduction in the amount of data is possible. With an example data rate of 192 kbps, which … [Read more...]
What is FLAC (Free Lossless Audio Codec) Audio Format
Free Lossless Audio Codec (FLAC) is a codec for lossless audio data compression that is being developed by the Xiph.Org Foundation. It is freely available and its use is not restricted by software patents. Development of FLAC began in 2000. In 2004, the band Metallica announced that in the future they would not only sell their concert recordings in the lossy MP3 format, but would offer the … [Read more...]
What is DSD (Direct Stream Digital) Audio Format
DSD (Direct Stream Digital) is a method of digital audio signal storage based on the principle of pulse density modulation (PDM). DSD is also a registered trademark of Sony Corporation. In principle, a DSD data stream can be stored on any digital storage medium of sufficient size. Corresponding files can be obtained from music download portals. Read about various audio file formats. In DSD, … [Read more...]
What is Streaming Media?
Streaming media, commonly referred to as streaming, refers to the simultaneous transmission and playback of video and/or audio data via a computer network via a data stream. The program that is transmitted is referred to as a stream; if the transmitted content takes place in real time, as a live stream. In contrast to downloading, the goal of streaming is not to create a copy of the media for the … [Read more...]
What is Mobile Commerce
Mobile commerce is a special form of electronic commerce using wireless communication and mobile devices. Mobile commerce refers to any type of business transaction in which the transaction partners use mobile electronic communication technologies (such as mobile communications, wireless LAN or Bluetooth) in connection with mobile devices in the context of service initiation, service agreement or … [Read more...]
What is a Triac?
Triac is an abbreviation for triode for alternating current. Terms such as bidirectional thyristor triode or symistor can also be found. It is an electronic component with a semiconductor layer structure, which in principle represents an anti-parallel connection of two thyristors. This makes it possible to switch both half-waves with alternating current, whereas a single thyristor can only switch … [Read more...]
