BizMic Multiples BizMic Multiples is an IT company that manages the Gauteng Province database system. In the past, they built a system that stores and accesses records of all the SA citizens in Gauteng Province in a direct access table. A direct access table involves the creation of a big array and uses phone numbers as an index in the array. As time goes on and the population continues to grow, it has now become very difficult to access a record from the traditional method. The system has now become very slow due to a large amount of records stored in it. The BizMic Multiples IT Company has consulted with an auditing firm who recommended a system that uses an array that stores pointers to records corresponding to a given record. This system, known as Hash Data Structures or simply Hash Table, is intended to improve on the existing system. As the lead IT intern at BizMic Multiples, your unit (you and your team members) is saddled with the responsibility of overseeing the success of the…

- _______________ is a special purpose programming language for accessing and manipulating data stored in a relational database.arrow_forwardProblem statement: Assume that you are an employee of a consultancy company that specializes in the analysis, design, and implementation of database systems. Southern Arkansas University (SAU) IT Group has recently approached your company with a view to implementing a database system for SAU, but they are not familiar with the development process. You are required to present an overview of the fact-finding techniques that your company intends to use to support the development of SAU’s database system. With this task in mind, create a 6-page report (Times New Roman, 12 font-size, double space) that describes each fact-finding technique and how the fact-finding techniques will be used throughout (each step of) the development of the database system.arrow_forwardExplain in your own words: a.)

- I understand the purpose of a database, which is to make data record-keeping easier for any company. And I'm aware of the hardware requirements. The concept of programming the rules and structure of a database is the area in which I am most confused. A database, in my mind, is a chart (or many charts) containing fields that are used to hold records. Then, of course, those records in one chart interweave with those in other charts, necessitating the creation of chart linkages. The concept of developing a framework for the data to fit into is where I get stuck. Are we creating metaphysical venues to store data, or are we just recording relationships between data saved on a variety of platforms?arrow_forwardHow about a lengthy description of the database's file system?arrow_forwardI understand the intentions of a database, being to streamline the data record-keeping of any organizations. And I understand the hardware needed to do such. The area I find myself the most lost in is the idea of programming the rules and structure of a database. In my head a database is a chart (or multiple charts) with fields that is used to store records. And then those records stored in one chart intertwine with other charts of course so we need to have relationships between the charts. Where I get lost is in the thought of programming a structure for the data to fit in. Are we making metaphysical locations to store data or are we just writing relationshipds between data that is stored on a plethora of different options?arrow_forward
