What is NoSQL?

• Doesn’t use SQL • Uses a custom query language

• A “non-relational” database• Means different things to

different implementations• Favors speed & scalability over

features• Does not replace RDBMS

A concept, not a standard.

Speed

Features



What is

• A document orientated database• Documents are represented as Name : Value

pairs in BSON format• Binary version of JSON or JavaScript Object

Notation (with some minor differences)• Embedded documents and arrays reduce

need for joins• Dynamic schemas – allows for unstructured

and complex data



MongoDB Document Example{ "firstName":"Jack", "secondName":"Jones", "age":30, "phoneNumbers":[ {fixedLine:"1234"}, {mobile:"5678"} ], "residentialAddress":{

lineOne:"…", lineTwo:"…", city:"…", state:"…", zip:"…", country:"…"

}}

• Names are in quotes• String values are in quotes• Separated by commas• Curley braces represent objects

• residentalAddress is an embedded object

• Square braces represent arrays• phoneNumbers is an array of objects



MongoDB Vocabulary

RDMS/SQLDatabase

TableRecord / Row

ColumnPrimary Key

IndexCursor

Schema

MongoDBDatabaseCollectionDocumentFieldPrimary KeyIndexCursorSchema



Other Notes

• All documents have an _id field• Collection exists when documents added• Documents within collection don’t need a consistent

schema, but typically are similar• Query language supports complex logic, including

regular expressions



MongoDB Installation

• Straight forward install • https://www.mongodb.org/downloads (32-bit & 64-bit)

• Setup environment – folder for database• Default is c:\data\db

• Start MongoDB: mongod.exe [options]• Or setup as a service . . .

• Tutorial• http://embt.co/install-mongodb-windows [MongoDB.org]• http://embt.co/connect-mongodb [DocWiki]

https://www.mongodb.org/downloads

MongoDB Units & Components

• Units• FireDAC.Phys.MongoDB - Driver• FireDAC.Phys.MongoDBCli – Call Interface• FireDAC.Phys.MongoDBWrapper – Wrapping classes• FireDAC.Phys.MongoDBDef – Connection definition

• Components• TFDConnection – used to make the DB connection• TFDMongoQuery – Run queries to a collection• TFDMongoDataSet – Connects to a MongoDB cursor• TFDMongoPipeline – Execute pipelines to a collection



Low-Level MongoDB Classes

• Wrappers - FireDAC.Phys.MongoDBWrapper• TMongoConnection: manage connections• TMongoDatabase: manage a databases and users• TMongoCollection: represents a collection• TMongoCursor: fetches a result set document

• Fluent style builders• TMongoUpdate builder• TMongoSelector builder• TMongoInsert builder• TMongoIndex builder
