Database engine

been many clear advancements in the space of databases. Two very common databases are MySQL and MongoDB. They are similar in many ways and also very different in how they deal with data. We will look at how they execute read queries and see what those similarities and differences are. Part 1: How a MySQL query is prepared and executed. For us to understand how a SQL database differs in running queries we…

Related Work: The problem of classifying objects in a relational database has been studied extensively within the multi-relational data mining community. There are two main approaches to deal with relational structure. The first approach is based on Inductive Logic Programming (ILP) to extend learning techniques so that they can handle relational data. On the other hand, the second approach, called Propositionalization, focuses on aggregating data in a single table so that traditional learning…

Database Driven Organisations To initiate about databases, they are valuable across the world by people as individuals or predominantly by businesses for various reasons in which I will evaluate below. The title derives from incorporating any amounts of data from small to large scaled into a base, a base is a foundation that brings this data into one area (usually software) for ease of access, management, processing and locating in an organised manner. Figure 1: Yell, (2016), Wok & Go Yell…

Before some of the advancements in technology, all records of information was saved and filed in cabinets for a specific amount of time before they were disposed of. Now most information will be kept within a database. A database is a group of records that comprise of people, places, or things. An example of a paper-based database is a telephone book. A telephone book has information of phone users in a specific location. Each user is listed by name, address and number. The listed…

According to Ewebarchitecture.com (n.d.), “MySQL can be integrated into a Web environment, and it supports C, Pearl, Java via the Java Database Connectivity API (JDBC), and Python programming.” There is a lot of flexibility with MySQL to work with these programming languages and can be used with Windows, Linux, and UNIX operating systems. MySQL is a client/server system in which software is installed on a computer to access the database on a server to save, modify, and query data. With MySQL,…

The scrum framework is created Jeff Sutherland and Ken Schwaber in the year 1993.The word ‘Scrum’ has been derived from a paper titled “The New Product Development Game” written by the thinkers Takeuchi and Nonaka.Scrum is often compared to the team of rugby due to the analogies of small teams working for a single objective. Scrum is one of the most popular agile development methodologies and one of the easiest transitions from the waterfall approach, since it’s typically requirements-driven…

This week we learned lots about the decomposition of our relations we are creating in the database as well how to make the relations into normal forms, which there are three normal forms. I learned that there can be data that is redundant and therefore not useful for the database. This data has no integrity and can be misplaced and even confuse how the data can be used and retrieved. This type of problem must be avoided. I had a hard time understanding how the breaking down of one relation into…

Physical properties of PHB: PHB physical properties similar to polypropylene. However, PHB is perfectly isotactic and does not include any chain branching like, for instance, PE. During processing, it flows easily. It is insoluble in water and soluble in chloroform and other chlorinated hydrocarbons. It exhibits good barrier properties against oxygen and compared to other biopolymers. It possesses better physical properties than polypropylene for food packaging applications. (Chaijamrus &…

Introduction and Methodology As you know, the data collection has two types which are primary and secondary data. The primary data are collecting information from different sources such as observation, interviews, and survey or questionnaire. While the secondary data is information collected previously by someone else and it is available on the internet or journals and in a company the records. I choice primary data collection, which is a questionnaire. Thus primary data has advantages which…
