COMP23111 Fundamentals Of Databases Notes | Assignment Help | Syllabus
Country: United Kingdom
University: University Of Manchester
In both commercial and scientific settings, databases are critical, though generally unseen, components of contemporary computer systems. Data management has progressed from application-specific file management to enterprise-wide methods that see data as one of contemporary organizations’ most valuable assets and, as such, a major element in their capacity to compete and flourish. Database management systems (DBMSs) are the critical piece of software infrastructure required at this organizational level to deliver the desired outcomes with consistent quality and robust efficiency. A contemporary DBMS is a marvel, including numerous advancements in algorithms and data structures, programming language theory, conceptual modeling, concurrency theory, and distributed computing in its internal design and broad usage. As a result, database research is a data-centric exploration of many of today’s most fascinating subjects.
This training unit’s purpose is to expose students to the basic ideas and methods that underpin contemporary database management systems (DBMSs).
The training section looks at why people want to manage data as an asset and presents the fundamental architectural concepts that underpin contemporary database management systems. Different architectures and the application environments they provide are examined.
The relational model of data, relational database languages, and SQL, including views, triggers, embedded SQL, and procedural methods (e.g., PL/SQL), are then described and motivated in the course unit.
Students will learn how to create a conceptual data model (using the Extended Entity Relationship paradigm), map that model to a target implementation model (using the relational model), evaluate the latter’s quality using normalization, and write SQL queries against the improved implementation model to validate the resulting design against the data requirements. The Oracle DBMS is utilized for practical work.
The basics of transaction management, such as concurrency (e.g., locking, 2-phase locking, serialisability) and recovery (rollback and commit, 2-phase commit), as well as file organization (e.g., clustering) and the use of indexes for performance, are also covered in this training unit.
Finally, the course unit looks into database security by looking at the risks and solutions that are accessible. These include possible theft and fraud, as well as a loss of confidentiality, privacy, integrity, and availability in the event of the former. These mainly comprise methods for authorisation and access control, including the use of views for this purpose in the case of the latter. By presenting exemplars such as the 1995 EU Directive on Data Protection and the 1998 UK Data Protection Act, the course unit also tackles the subject of legal frameworks that give rise to responsibilities on the part of database professionals.

Writing an essay is no simple feat. Every year, students spend hours upon hours poring over books, compiling annotations and looking for pieces of information that can be put in order to create a coherent argument. Essay writing is a long and lengthy
process and not everyone picks it up as easily as others. That’s why many students choose to buy essays online that they can use as study material to help them plan their own university essays. However, not every essay writing service is capable of writing essays to the standard you need.
While there are many different services that allow you to buy an essay, you’re not always guaranteed to get what you expect. Getting cheap UK essays is never going to benefit your grade and you
never know who is writing them or whether or not they are capable of responding to your assignment. Some of the poorer quality essay writing services employ writers that don’t speak English, don’t understand the subject they are writing about
or, worst of all, choose to plagiarise other people’s essays. However, when you buy an essay from us, we guarantee that the work that you will receive is of great quality and worthy of a high grade.
At The Uni Tutor, you can buy an essay from an expert with experience in your field of study and capable of fully researching, sourcing and writing your essay to an exceptionally high standard.

I’m [student name removed] from [school name removed] and I’m here to share some of my experiences with The Uni Tutor with you. Before I
found The Uni Tutor I literally spent months trying to find research material for my dissertation but I was seriously struggling to establish a proper logical structure and argument. My deadline was looming. I was panicking. A friend of mine said
that he had used The Uni Tutor. She said they were amazing and helped her obtain a 1st Degree. So I gave them a call.
I’m writing to thank The Uni Tutor team. My writer David Franzi wrote an amazing essay. It helped
me in gaining a top grade. The order came on time, and was plagiarism free. I’ve now been a customer for over 10 essays.
