- Access path A database table is composed of records and fields hold data. Data is stored in records. A field is a part of a record and contains a single piece of data for the subject of the record. The access path for finding the list of books is AUTHOR: AuthorID, Lname BOOKAUTHOR: AuthorID, ISBN BOOKS: Pubdate, ISBNAn E-learning website needs your help to design its database. They need to store information about teachers and online tutorials. Each teacher has a unique ID, name, and at least one field of specialty. Teachers form groups to prepare online tutorials. Each group has unique name and at least one teacher as a member. Each online tutorial has a title, date and organized by exactly one group. The title of the tutorial is unique for the group. Each tutorial consists of several sessions, described by their titles and durations. Naturally, each session is presented by one teacher and belongs to exactly one tutorial. In addition, sessions on the same tutorial have different titles. Design an ERD for this application. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.Instructions: Create a dimensional model for a particular business process involving gym membership. A customer can sign up for a membership of say one, three, six or twelve months. I want to make it easy to query to identify current members, members who expired in the last month, members who renewed in the last month, those who are pending expiry etc. If I have a basic model with a fact table representing a gym membership say start_date_key end_date_key membership_attribute_key customer_atrribute_key fee with associated dimension table for date, membership attributes such as length, customer attributes and so forth. On a particular day, the active members are those with a start date before the day and an end date after that day. Those who will expire next month are those where the end date is in a particular date range.

This should show your table names and column names. Show the relationships between the tables. Write a statement explaining your database design (why did you use the tables that you did). Create a database in Access based on your diagram. Include all tables in your diagram. Tables should each have a minimum of 5 rows. Create 5 SQL statements using your database. At least 2 of these should be manipulation statements (insert, update, etc). The others should be select statements. Explain what your sql statements do and how they would be useful to your database.
