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…

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.

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,…

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…
