Understanding the City Planning Notion
City planning consists of grouping the different applications used in the information system into "city planning blocks" of similar functionality.
Several strategies for creating these groups can be defined. It is therefore possible to define several city plans that describe the information system from different points of view.
The information system processing is broken down into different levels:
• Area
This is the highest level in the breakdown of the enterprise information system. For most companies, there is a data acquisition area, an information processing area, a management area, a repository area, etc.
• District
The district groups the processing that can correspond to an activity or a business function, and therefore to a type of information.
• Block
The block corresponds to the basic component of the city plan. A block is a homogeneous set of data and processings. Computer applications are grouped within the city planning blocks.
• Etc.
Additional levels can be specified if required.
