Databases are the cornerstone of any software application. You will need one or more databases to develop almost any type of software application: web, enterprise, embedded systems, real-time systems, AI, ML, HPC, blockchain, IoT, and many others.

Referential integrity constraints help organizations prevent accidental database corruption by authorized users. Database management software allows users to define validation and integrity rules and conditions to ensure that data satisfies semantics.

Structured Query Language (SQL) is a standardized programming language for managing relational databases and performing various operations on the data within them. Originally created in the 1970s, SQL is frequently used not only by database administrators...

Amazon DynamoDB is a fully managed, multi-region database with built-in security, in-memory caching, and backup and restore capabilities. The database's popularity can be seen in the number of large companies using it, such as AirBnB, Toyota, and Samsung....

The massive popularity of MySQL has prompted many 3rd party vendors to create software to use it. These include development and management clients like Navicat for MySQL and monitoring tools like Navicat Monitor. While neither tool is free, they make a li...

A relational database is a database that stores data in a structured schema that identifies relationships between stored items of that data. A document database is a non-relational database used to store semi-structured data.
Databases will improve data ...

Databases are the basis for collecting, processing and displaying data. They aggregate information with common characteristics for easy management. You don't always need programming skills to create and use databases. Some online databases have the advant...

Polypropylene (PP), one of the most widely used general-purpose plastics, was first synthesized by Prof. Natta in 1954 and subsequently industrialized, thus opening a new chapter in polymer science and engineering (Zheng et al., 2017). PP is a thermoplast...

The oxides used were reagent grade commercial products (V2O5, MgO, ZnO,
Fe2O3, La2O3, CuO) or from appropriate salts. Mn3O4, NiO and
Co3O4 is obtained from basic carbonates by heating at 803 K
3 hours, identified by infrared spectroscopy [11]. Decompos...

Organic nitrates play an important role as sinks or temporary reservoirs of nitrogen oxides and in the generation of atmospheric ozone (Perring et al., 2013, 2010; Ito et al., 2007). They are formed by the degradation of volatile organic compounds (VOCs) ...

Vitamin B5 exists in food in three bioactive forms [1]: pantothenic acid, coenzyme A (CoA) and acyl carrier protein (ACP). Calcium or sodium pantothenate are the forms commonly used as infant formula supplements [5].

By chance, we noticed a massive fungal growth causing lipolysis of margarine which had been accidentally contaminated with blue cheese. The fungus also produces large amounts of methyl ketones, including 2-pentanone.

Chemostat glucose-limited synthetic minimal medium containing (per liter) 0.1 g calcium chloride, 0.1 g sodium chloride, 0.5 g magnesium sulfate, 1 g potassium dihydrogen phosphate, 5 g ammonium sulfate, 500 μg boric acid, 40 μg sulfuric acid Copper, 100 ...

With increasing energy demand and the goal of reducing global warming, there is a need to transition away from fossil fuel combustion in the transport sector to second-generation biofuels, as it could ultimately contribute to reducing net carbon emissions...
