Relational Database
A relational database (RDB) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. A Relational Database Management System (RDBMS) is a type of database management system that stores data in a structured format using rows and columns. Many relational database systems are equipped with the option of using SQL (Structured Query Language) for querying and updating the database. History The concept of relational database was defined by E. F. Codd at IBM in 1970. Codd introduced the term ''relational'' in his research paper "A Relational Model of Data for Large Shared Data Banks". In this paper and later papers, he defined what he meant by ''relation''. One well-known definition of what constitutes a relational database system is composed of Codd's 12 rules. However, no commercial implementations of the relational model conform to all of Codd's rules, so the term has gradually come to describe a broader class of database systems, which at a ...

Frankford Arsenal
The Frankford Arsenal is a former United States Army ammunition plant located adjacent to the Bridesburg neighborhood of Northeast Philadelphia, Pennsylvania, north of the original course of Frankford Creek. History Opened in 1816 on of land purchased by President James Madison, it was the center of U.S. military small-arms ammunition design and development until its closure in 1977. Among the many other products manufactured at the arsenal were fire-control and range-finding instruments, and gauges for these components. With the outbreak of the Civil War, the arsenal's commander, Josiah Gorgas, resigned and joined the Confederate States Army in deference to the wishes of his Alabama-born wife and reported to the Confederate capital in Richmond with a large supply of U.S. Army guns and ammunition. By the end of the war, the arsenal employed over 1,000 workers. It served as a major site for the storage of weapons and artillery pieces; a depot for the repair of artillery, ...

Technical Writers
A technical writer is a professional communicator whose task is to convey complex information in simple terms to an audience of the general public or a very select group of readers. Technical writers research and create information through a variety of delivery media (electronic, printed, audio-visual, and even touch). Example types of information include online help, manuals, white papers, design specifications, project plans, and software test plans. With the rise of e-learning, technical writers are increasingly hired to develop online training material. According to the Society for Technical Communication (STC):L. Lin. (2017, November). What is technical writing? eb log post Retrieved from http://www.stc-psc.org/what-is-technical-writing/ In other words, technical writers take advanced technical concepts and communicate them as clearly, accurately, and comprehensively as possible to their intended audience, ensuring that the work is accessible to its users.

MySQL
MySQL () is an Open-source software, open-source relational database management system (RDBMS). Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, and "SQL", the acronym for Structured Query Language. A relational database organizes data into one or more data tables in which data may be related to each other; these relations help structure the data. SQL is a language that programmers use to create, modify and extract data from the relational database, as well as control user access to the database. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer's storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups. MySQL is free and open-source software under the terms of the GNU General Public License, and is also available under a variety of proprietary software, proprietary licenses. MySQ ...

Nested Set Model
The nested set model is a technique for representing nested set collections (also known as trees or hierarchies) in relational databases. It is based on Nested Intervals, that "are immune to hierarchy reorganization problem, and allow answering ancestor path hierarchical queries algorithmically — without accessing the stored hierarchy relation". Motivation The standard relational algebra and relational calculus, and the SQL operations based on them, are unable to express directly all desirable operations on hierarchies. The nested set model is a solution to that problem. An alternative solution is the expression of the hierarchy as a parent-child relation. Joe Celko called this the adjacency list model. If the hierarchy can have arbitrary depth, the adjacency list model does not allow the expression of operations such as comparing the contents of hierarchies of two elements, or determining whether an element is somewhere in the subhierarchy of another element.
