Well-Analysed Requirements
o You may use Event Table (see lecture 6) form to state business activities for the
system you captured.
o All entities and their attribute-values should be stated,
o All flow of information should be clearly stated,

System Design
1. Entity Relationship diagrams to represent the data storage requirements for London Visual Arts (LVA) gallery System, including the attributes mentioned.
2. Draw Data Flow Diagrams (context, and level0) based on business activities
for the system above, by using tools are available such as Microsoft Visio .
Scenario of the Case Study :
The managing director, John Lee of London Visual Arts (LVA) has a small art gallery based in Notting Hill in West End of London. It has no fixed collection of
paintings of its own, but simply puts on exhibitions of paintings belonging to museums or living artists. In the past, it has relied on a paper filing system to
organise exhibitions, but John Lee wishes to expand the business, with a short-term strategy to gain a web presence, with the availability of exhibition information,
paintings, artists and captured images of artist. John has hired you as a systems analyst, to analyse and capture the current workings and to recommend a project
design methodology approach. The following is a description of how the current system works.
Artists who would like to exhibit contact LVA with details of their paintings, the styles and where possible photographs. The curators at LVA also contact various
museums and other galleries to find out about paintings held elsewhere. Details of all paintings and their artists are held in the paintings file.
To organise a new exhibition, the curators meet and go through the paintings file and collect together paintings that would make a good exhibition. They also make sure
that the new exhibition does not overlap too much with other past or planned exhibitions. With living artists, the curators often have to confirm with the artist that
the painting is still available and has not been sold. The details of the new exhibition are held in a special folder for that exhibition.
Having devised an exhibition, the curators go through the list of rooms at the gallery to find an available room of suitable size and a possible set of dates for the
exhibition. Once the dates are fixed, the room is reserved and details of the exhibition and its dates are sent to the promotional artist who prepares fliers and
posters for the exhibition. These are sent out to LVA’s various advertising outlets for distribution.
The final details of the exhibition are also sent to the appropriate artists and museums, who should reply to confirm and to give details of the transport required to
get the paintings to LVA. These requirements are kept in the exhibitions folder and also passed on to a transport company. The transport company ensures that the
paintings arrive safely in time for the exhibition.
