Data Confidentiality Policy

In an outsourced database model, data is stored by an external service provider. This means that the owner of the database allows the service provider to host the database. Data security issues of the stored data arise because the mechanisms of creation, storage, updating and accessing the data within the database may compromise the data confidentiality and integrity. Organizations should therefore implement data confidentiality policy that will provide practical schemes that will guarantee the security of the database from attackers (Allen, 2002).

Describe with examples the differences between a Lifecycle, methodology and modeling language.

Methodology language is the systematic study of methods used in the information technology discipline. It’s also the documented process of definitions, explanations and procedures for management of software projects. An example of methodology language is the software development methodology is the Rational Unified Process which is promoted by Rational Software Company. The six disciplines of RUP methodology are business modeling, requirement gathering, analysis and design, process of software development and implementation and software application testing. It uses four phases in developing a software and this are; inception phase where a project case is prepared and discussed, elaboration phase where proper analysis of risk is conducted, construction phase that focus on development part of the project and transition phase which involves production and testing of the software . Another example of a methodology language is Agile Unified Process which describes a simple and east to understand approach of developing software of business applications. It has seven disciplines which are model, implementation, test, deployment, configuration management, project management and environment.
