MongoDb - Projeto Final

Autor: Welder Marcos Data 1454201680248

Para qual sistema você usaria o MogoDB (diferente desse)?

Usaria para um sistema de gerenciamento de notícias, pois acredito que o formato de documento seria o mais adequado para notícias;

Qual a modelagem da sua coleção de users?

User: {
	name: String,
	bio: String,
	date-register: Date,
	avatar: BINARY,
	background: BINARY,

	auth:{
		username: String,
		email: String,
		password: String,
		last_acess: Date,
		online: Boolean,
		disabled: Boolean,
		hash-token: String
	}
}

Qual a modelagem da sua coleção de projects?

Project:{

	name: String,
	description: String,
	date_begin: Date,
	date_dream: Date,
	date_end: Date,
	visible: Boolean,
	realocate: Boolean,
	expired: Boolean,
	visualizable_mod: Boolean,
	tags: [String],

	members:[{
		type: [String],
		_id: OBJECT_ID,
		notify: Boolean
	}],

	goals:[{
		name: String,
		tags: [String],
		description: String,
		date_begin: Date,
		date_dream: Date,
		date_end: Date,
		realocate: Date,
		expired: Date,
		historic: [Date],

		activity:[{
			_id: OBJECT_ID
		}]
	}]
}

Qual a modelagem da sua coleção retirada de projects?

Activity:{

	name: String,
	tags: [String],
	description: String,
	date_begin: Date,
	date_dream: Date,
	date_end: Date,
	realocate: Boolean,
	expired: Boolean,

	comments:[{
		text: String,
		date_comment: Date,

		files: [{		
			name: String,
			weight: String,
			path: String
		}]

		member: {[
			member_id: OBJECT_ID,
			notify: Boolean
		]}
	}]
}

Justificativa

Para o ambiente sugerido pela modelagem o maior número de documentos serão os referentes as atividades, pois cada projeto pode possuir inúmeros goals e dentro destes goals inúmeras atividades por isso está categoria de documentos merece uma coleção, ao meu ver essa netodologia de modelagem também se justifica pelo fato de deixar os documentos de projetos mais "leves".

Create - cadastro

  1. Cadastre 10 usuários diferentes.
//Lista de usuários
var usersList = ["Alpha", "Beta","Gama","Delta","Epsilon","Zeta","Eta","Theta","Iota","Kappa"]

//Função pra criação do campo hash nas autenticações, neste caso usei o nome como paramentro
var toHash = function(s){
	var hash = 0
	if(s.length == 0){ return hash}
	for(i = 0; i < s.length; i++){
		char = s.charCodeAt(i)
		hash = ((hash<<5)-hash)+char
		hash = hash & hash
	}
	return hash
}

usersList.forEach(function(u){
	var user = {
		name: u,
		bio: u + " bio",
		date_register: new Date(new Date().getTime() - (24 * parseInt(_rand() * 1000)) * 60 * 60 * 1000),
		avatar: null,
		background: null,
		auth: {
			username: u.substr(0,3),
			email: u + "@email.com",
			password: u.split("").reverse().join(""),
			last_acess: new Date(new Date().getTime() - (24 * parseInt(_rand() * 1000)) * 60 * 60 * 1000),
			online: (parseInt(_rand() * 1000) % 2) == 1 ? true : false,
			disabled: false,
			hash_token: toHash(u)
		}
	}
	db.users.insert(user)

  1. Cadastre 5 projetos diferentes.

      • cada goal com pelo menos 3 tags;
