In a DSS workflow, a SQL pipeline is a procedure that mixes numerous subsequent recipes (each using the same SQL engine). Then, a single job activity containing these integrated recipes—which may be both visual and "SQL query" recipes—can be executed. Typically, a SQL query will be converted into an expression in relational algebra, which is a series of relational operations. If we do one operation at a time, we incur too much cost because we need to create temporary files on a disc to store the outcomes of these temporary operations. Large temporary files must be created and stored on ... Read More

A deductive database in SQL or any other database system is a tool that can draw conclusions about new facts based on the rules and information already present in the database. In deductive databases, datalog is the language commonly used to express facts, rules, and queries. The formula, when expressed in clausal form, consists of a number of clauses, each of which is made up of a number of literals joined exclusively by logical connectives marked with the OR symbol. The following quantifiers are possible in a formula − Universal quantifier − It may be read as "For all x, ... Read More

In this article, we will understand the types of Bridge Protocol Data Unit (BPDU). It is the process in which switches are presented in the STP domain that enables exchanging messages. The Spanning Tree Algorithm would use the transmission of BPDU to recognize the type of network. After the devices are attached to the ports, the data transmission does not start immediately rather they start moving from one state to another. This movement is used by the BPDU to determine the topology of the network. Hence, enabling the participation of the switches to gather information about one another. Types of ... Read More

Optical fiber is a technology through which data passes in the form of light at high speed. It is a thin transparent cable type that is flexible and can be bent easily Fiber optics cable can be joined many times in one installation using joints. Joints are used to transfer light from one fiber optic cable to another fiber optic cable and are made up of plastic or glass material. In this article, we will explore the various types of Joints in Optical Fiber. Types of joints in optical fiber Unlike the normal joints, these are the special joints used ... Read More

Introduction Exploratory Data Analysis (EDA) is the process of summarization of a dataset by analyzing it. It is used to investigate a dataset and lay down its characteristics. EDA is a fundamental process in many Data Science or Analysis tasks. Different types of Exploratory Data Analysis There are broadly two categories of EDA Univariate Exploratory Data Analysis – In Univariate Data Analysis we use one variable or feature to determine the characteristics of the dataset. We derive the relationships and distribution of data concerning only one feature or variable. In this category, we have the liberty to use either ... Read More

Introduction Data science and machine learning are topics that are expanding quickly and have a strong need for qualified personnel. Not everyone who is interested in these areas, though, would choose to go into data science or machine learning engineering as a profession. The good news is that there are alternate job routes that let people use their expertise in these subjects while pursuing other passions or interests. In this post, we'll look at several alternative career paths for those with a background in data science or machine learning and how their talents might be used in different fields. Alternate ...

Data analytics is the science and application of analyzing data to make conclusions about a specific problem or subject. The measurement and evaluation of data is considered an essential part of most business processes, and it’s these measurements that data analytics uses to gain insight into what’s happening within the business environment. Data analytics is about managing, analyzing, and exploring data for purposes of making decisions. It’s the process of using analytical methods to obtain answers that were never thought of before. For example, a human won’t be able to see what each digit in this number, 223, means ... Read More

IoT information investigation stages enable organizations to assess and imagine sensor information from web-based gadgets. They are apparatuses used to comprehend the persistent progression of unstructured, organized, and time-series information produced by associated gadgets for associations to grasp verifiable information and figure out future outcomes. Billions of associated IoT gadgets are creating a gigantic measure of information consistently. In the meantime, as the IoT blasts, this information age has dramatically developed. Investigating this large lump of information can be exceptionally furious, and examination devices are extremely significant in gathering, checking, and dissecting this information. Underneath, we have featured 10 of ... Read More

SDHC and SDXC − what are they? What is the difference between SDHC and SDXC, did you know? SDHC vs SDXC will be discussed in this post. Additionally, it provides detailed instructions on basic safety measures to take when using these cards. A detailed Difference Between SDHC and SDXC is mentioned in this article. There are two different varieties of SD cards: SDHC and SDXC. Consequently, you must first study about the SD card in order to know the SDHC and SDXC. Secure Digital cards, or SD cards, are used to store files, music, photographs, and other types of data. ... Read More

Introduction A checkpoint in a database management system (DBMS) is a process that saves the current state of the database to disk. This allows for faster recovery in the event of a system failure or crash. In this article, we will explore the concept of checkpoints in DBMS, including how they work, the different types of checkpoints, and their real-world applications. What is a Checkpoint? A checkpoint is a process that saves the current state of the database to disk. This includes all transactions that have been committed, as well as any changes that have been made to the database ...
