A private kindergarten, Happy Learning, wants to build a database to manage their operations. You were assigned to create an initial design based on the following customer description of their operations. There are 3 age levels in the kindergarten (turtles, foxes and monkeys). At each level there 3 classes (red, blue and green). For a class we keep a code based on the initial of group color and level (e.g. RT for red turtles, GF for green foxes). Each class has a room number and a phone number (with the format (999) 999-9999). Also, each class has a maximum capacity (between 25 and 29). For some classes we will keep brief directions to the class location in the building (at most 130 characters). For a student we will keep the name (first, last, middle each at most 22 characters), any nickname (at most 20 characters), date of birth, address, and the class in which the student is currently enrolled. We will process students based on their first and last name, or nickname, if present. We will process the address based on the city (at most 15 characters), zipcode-5 and street (at most 35 characters) to identify recruiting areas. For each student we will keep information about one or more parents (or caretakers). A parent may have several students enrolled in the kindergarted. For a parent (or caretaker) we will keep the name (first, last, middle), home phone number, mobile phone number, work phone number, (same format as above), the personal email (at most 30 characters) and relationship to the child (e.g. father, mother, grandfather). At least one type of phone is required, but some parents may not provide all types of phone numbers. Some parents do not provide emails. We will process parents based on their last name. Each class has a teacher assigned. A teacher is assigned to one or more classes. For a teacher we keep the name (first, middle, last), home phone number, work email, personal email (with the format as above),the graduated college and their highes degree (e.g. BS, MS, MA, ... - a maximum five characters code) and the area of the degree (at most 25 characters). All the teachers must have at least bachelor degree. We will process teachers based on their first and last name, phone, email. The format for the name, phone, email as described above.

for the statement above provide the following:

Conceptual Analysis

Before you start a detailed analysis you must figure out which are the main elements in your design Identify the main entities involved Identify the main relationship involved. Identify the relationship type and explain how you obtained it For many to many relationships identify the bridge, and the two other relationships needed.

Entities Analysis

You must analyze the entities identified including the bridges:

Entity name Entity description (a short paragraph) An attribute table, with one row for each attribute and with the following columns: Attribute name Attribute domain and size, e.g. CHAR(10), INT, VARCHAR(30) Simple/Composite (without explanations) Single/Multi Value (without explanations) Required/Optional (without explanations) Unique/Duplicated (without explanations) The selected primary key and its type (simple/composite/surrogate). Any foreign key specifying the referenced primary key and entity. Relationship

Analysis Relationship name:

PARENT_ENTITY relationship name CHILD_ENTITY (the name is a verb or verb phrase 3rd singular) Relationship type with explanation Relationship strength with explanation Entities participation in the relationship with explanations Any special cardinality as needed, or state there is no special cardinality. Foreign key used for representation.

Entity Relationship Diagram After you finished the entity analysis you must draw the ERD in MySQL Workbench and include in your report the following screenshot(s): A signed screenshot (or more if needed) with the ERD done in MySQL Workbench (to sign a screenshot you write your name in a text object visible in the screenshot; crop the image to show only the ERD and the text object) A screenshot for each entity (table) description in MySQL Workbench (crop the image to show the entity name and attribute table). Be sure you correctly identify the entity name, attributes names, attributes domains, attributes characteristics (e.g. required/optional and unique/duplicated) and the primary key.
