"Question 1.1: ER Diagram for a Knowledge Management System Relational databases are often used to store the knowledge in a knowledge management system (KMS), for example to build a knowledge map. The KMS manages the relationships between the knowledge, knowledge carrier, and the technology that will be introduced in the company. Your company decided to develop this kind of KMS. As a knowledge manager, you are given the task to specify requirements for data included in the system and their relationships. The following data should be included in the KMS: Knowledge: Knowledge is for example data science, software development, hardware development, business development, project management, etc. Each knowledge has ID and name. Knowledge carrier: Knowledge carrier is the personnel who has the knowledge. Each knowledge carrier has ID and name. A knowledge carrier can either be internal carrier (employee) or external one. The external carrier has company name that he/she represents. A knowledge carrier can carry more than one knowledge and one knowledge can be carried by more carriers. Each internal carrier (employee) works in a department. A department can have many employees. Each employee can supervise many others but he/she can be supervised by another employee. The company wants to introduce new technologies, such as loT and big data. They want that the knowledge management system should be able to map the technology with the required knowledge. A technology requires one or more knowledge. Each knowledge can be required by more than one technology. The technology has ID and name. (10 P 1.12 Draw the ER diagram using drawing tool like power point, visio, etc.! The ER diagram has to include the following: a. Entities and their (key) attributes." b. The relationships, their attributes and cardinalities. C. IS-A and recursive relationships "Question 1.1: ER Diagram for a Knowledge Management System Relational databases are often used to store the knowledge in a knowledge management system (KMS), for example to build a knowledge map.
