Before jump on to KBIES

KBIES is implemented in python-Django web framework and MySQL database at its backend. As such installation of a recent version of Python is the first step. The way to get Python and MySQL installed really depends on what computing platform will be used for development and/or deployment. Because both Python and MySQL are platform-independent, platform for development can be different. Because development can often be done in friendly desktop environment, Windows platform is often the choice for development. To run a production server, Linux such as Ubuntu Linux is often used for its sound security and server features.

How can you deploy the entire system or updates from your development server to your production server? it has been proved that the easiest way is to use a tool called rsync . It is efficient and effective because it will only will only update the changes to the system on the target machine, such as your production server.

ZRBAC - The theory behind system design, development and deployment with KBIES

An organization is often structured in a hierarchy, and each node in the hierarcy is assigned with specific functions, such as functions of human resource, finance, and facility department. We call the entire organization main zone, and the nodes within the organization, under the main zone, sub-zones.

Employees working in each specific zone play specific roles assigned, and each role is played by carrying out specific actions. ZRBAC - Zoned Role-Based Access Control is based on the above analysis, can be used for system design, development and deployment in the following steps:

1. Zoning - to find out the sectors of the businnes within the organization, whcih will be mapped into zones. The existing departments such as human resources, finance and facility, of the organizational hierachy may be directly mapped into zones, so are the lines of business of the organizaion, such as teaching and research for a university, can also be mapped into zones. Let's call the orgonization for which an integrated system to be developed main zone \( Z \), and call sub zones identified under main zone \(z_1, z_2, ..., z_n\), we then have \[ Z = \{ z_1, z_2, ..., z_N \} \]
2. Roles identifying - For each identified zone \( z_i \), identify different roles an employee may play, to get a set of roles for \( z_i \). We then have \[ R^{z_i} = \{ {r^i_1}, {r^i_2}, ..., {r^i_M} \} \]
3. Apps designing - For each identified zone \( z_i \), also identify applications (apps in short) needed for the zone to function, to get a set of apps for \( z_i \). We then have \[ A^{z_i} = \{ {a^i_1}, {a^i_2}, ..., {a^i_Q} \} \]

   An app is a computer system designed for some specific purposes. For example, a research department within a university will need a system to manage fundings, a system to manage research projects, a system to manage publication. The university will need a system for course development, and a system for course delivery.

   It is quite often that one system can have sub systems, forming a hierarchy of systems. That's how a computer system is normally designed and developed. The technique is called divide-and-conquer, modular programming at high-level, or structured-programming at coding-level.

   An exampel of such a hierarchy is a course development system, which will have subsystems for exam development, assignment development, quiz development, learning content development, and other subsystems needed.

   Regardless of how big or small a system is, it serves its purposes by providing a suite of operations for intended users to perform. In computer programs, these operations are implemented with functions or methods. So, our next important step is

4. for each app \( a^i_j\), make a list of functions that can be called by a user, such that \[ F^{a^i_j} = \{ {f^i_{j1}}, {f^i_{j2}}, ..., {f^i_{jP}} \} \]
5. Actions authorizing - now for each identified role \(r^i_k\) in zone \( i \), identify the functions for app \( j \) in \( F^{a^i_j} \) to form a set of functions as follows \[ F^{r^i_k} = \{ f^i_{kj1}, f^i_{kj2}, ... f^i_{kjT} \} \] please note that apps identified for a role are different from apps often refereed to in Django. An app for a role actually refers to a function in the views file.
6. Create a folder on your file system for your web-based integrated IT solutions, let's call it i_solutions.
7. unzip the main_zone package into a folder. If not changed, you will see a single folder named main_zone, which is the toppest folder of the main zone.
