1.0 INTRODUCTION 

Databases play an integral part in commercial domains, they provide users with a tool in which tostore, model and retrieve data. Database development is fundamental in the area of computingand ICT within organisational contexts. Database Management Systems (DBMS) provide thesystems, tools and interfaces by which the organization can manage their information and use it to assist in the effective running of the organization. Databases offer many links to otherssuch as programming, systems analysis, HCI, as well as embracing issues of compatibility andend-user interfacing.

This unit explores database architecture, DBMS and the use of databases in an organizational context. Database design techniques are investigated and successful learners will be able toapply theoretical understanding to design, create and document a database system.

Teaching and Learning Activities         

The module tutor(s) will aim to combine lectures with tutorial activities. This environment will provide opportunities for the student to understand the course material through case study and text and to apply it in a practical way. The intent is to facilitate interactive class activities, and discussion about the significant role of research in a global and local business environment.

2.3       Teaching Ethos

The college’s approach towards teaching and learning is simple and effective. The main aim of UKCBC is to assist learners in maximising their potential by ensuring that they are taught clearly and effectively. This will enable students to engage in the learning environment and promote success in both their academic studies and subsequent career.

2.3.1 Methods of Delivery:

LECTURES:

These will be developed around the key concepts as mentioned in the indicative course content and will use a range of live examples and cases from business practice to demonstrate the application of theoretical concepts. This method is primarily used to identify and explain key aspects of the subject so that learners can utilise their private study time more effectively.

SEMINARS:

These are in addition to the lectures. The seminars are designed to give learners the opportunity to test their understanding of the material covered in the lectures and private study with the help of reference books. This methodology usually carries a set of questions identified in advance. Seminars are interactive sessions led by the learners. This method of study gives the learner an excellent opportunity to clarify any points of difficulty with the tutor and simultaneously develop their oral communication skills. 

CASE STUDIES:

An important learning methodology is the extensive use of case studies. They enable learners to apply the concepts that they learn in their subjects. The learners have to study the case, analyse the facts presented and arrive at conclusions and recommendations. This assists in the assessment of the learner’s ability to apply to the real world the tools and techniques of analysis which they have learnt. The case study serves as a supplement to the theoretical knowledge imparted through the course work.

Plagiarism:

Any act of plagiarism will be seriously dealt with according to the colleges and awarding bodies’ regulations. In this context the definition and scope of plagiarism are presented below:

Plagiarism is presenting someone’s work as your won. It includes copying information directly from the web or books without referencing the material; submitting joint coursework as an individual effort; copying another student’s coursework; stealing coursework form another student and submitting it as your own work.Suspected plagiarismwill be investigated and if found to have occurred will be dealt with according to the college procedure. (For further details please refer to the plagiarism policy and the student code of conduct.)

Assessment:

The module will be assessed meeting all the LO as specified by the awarding body, Ed Excel.

Please read the instructions carefully while addressing the tasks specified. 

Contribution: 100% of the module

Case Study

Shoengalleric is an Art Gallery based in China which was established in 2010. Since then, the company has grown steadily and now has galleries in operation in the main cities in China. The Gallery has arts of different subjects. The Gallery fulfil the requirements of diverse clientele. They have a workforce of more than 500 staff operational in all the branches.

However, the company is now so large that more and more administrative staff are being employed to cope with the ever-increasing amount of paperwork due to the outdated office based systems. Furthermore, the communication and sharing of information within the company is poor. The Director of Company, Mr. Peng Wang feels that too many errors are being made and that the success of his company will be short-lived if he does not do something to remedy the situation. He knows that a database could help in part to solve the problem and has approached you to help in creating a database application to support the running of the Shoengalleric Art Gallery operations.

The Director, Mr. Peng Wang has provided the following hierarchy and brief description of how Shoengalleric Art Gallery operates:

Director: Oversees the long terms goals for the gallery.

Manager: Each Gallery has a Manager. The Manager is responsible for the day-to-day running of the gallery branch.

Administrator: Involved in complete administration aspects like hiring personnel, managing contracts with various artists from the cities.

Technician: Oversees all the technical requirements with respect to the installations of exhibitions i.e., oversees operation and documentation of art collections in the gallery. Working alongside him are the technical assistant supporting him in all the technical operations.

Preparator: Involved in the preparations of the exhibitions in terms of installations and dismantling of the exhibition art works and also monitors environmental controls for the gallery.

Gallery Assistant: Opens, closes and monitors the gallery and also involved in photography in the gallery.

Booking Assistant: Involved in all the operations related to the bookings from the clients who visit the Gallery for the exhibition.

The Gallery produces many exhibitions of the art work available in the Gallery. Artists provide the gallery with the installation instructions. All exhibitions are documented by the Gallery Assistant and a single page labelled diagram is created for each of the art work for the exhibition layout.

Visitors visiting the gallery may be interested in buying the artwork so every piece of artwork has to be priced as per the instructions from the artist.

Galleries keep information about artists, their names (which are unique), birthplaces, age and style of art. For each piece of artwork, the artist, the year it was made, its unique title, its type of art (e.g., painting, lithograph, sculpture, photograph), and its price must be stored.

Pieces of artwork are also classified into groups of various kinds.  For example, portraits, still lifes, works by Picasso, or works of the 19th century. A given piece may belong to more than one group. Each group is identified by a name (like those just given) that describes the group.

Finally, galleries keep information about customers. Visitors who visit the Gallery need to make a booking in advance to see the resources available. For some events, the Gallery is open to all and they do not charge any fees for visits.

For each customer, galleries keep that person’s unique name, address, total amount of Renminbi spent in the gallery (very important!), and the artists and groups of art that the customer tends to like.

The gallery needs to store the information related to the upcoming exhibitions and displays in relevant files.

You have been recruited by ShoengallericArt Gallery to help them develop a database for supporting and effectively managing the operations of the Gallery. Your role as a Database Designer is to develop a DatabaseApplication by following the database developmental methodology.You should record all business assumptions that you made in the process.

(LO2 A.C 2.1 AND A.C 2.2)

Required

2.1- Analyze a database developmental methodology for the given case study.

2.2-Discuss entity-relationship modelling and normalisation for the given case study.
