The Society for Database administrators (SoDA) organizes many seminars where the members from various organizations present articles. They are planning to set up a database to record and keep track of seminars and papers presented by members. During each seminar, members present a number of papers. A paper can be presented in one seminar only. Relevant data to be stored about a seminar is its unique code, location, start date and end date. Relevant data to be stored about a paper is its unique number, title of the article, length, version, and type of article. A paper cites many other papers, and some of which are articles already present in the database. A paper can be authored by many members. A member may submit several papers and attend many seminars. Each submitted paper is reviewed by three reviewers who are also members. For each paper a member reviews, he/she assigns a recommendation. The recommendation can be either Accept, Revise and resubmit or Reject. Relevant data to be stored about a member is membership number, name, phone, Date of joining the society, and email. Each member belongs to an organization; an organization can have many members. An organization is identified by its name; other relevant data to be stored includes the address, phone, and web address. Each member is mentored by a senior member, and it is required to record who is mentoring whom. Develop the entity relationship model for the case. Make any assumptions deemed appropriate.
