    29/09/2016 Duração: 06min

    We look at how we as the developers of a Python class can interact with the moment of construction and destruction of various objects created using the class.

    29/09/2016 Duração: 07min

    We look at how we can make a new class by inheriting all of the attributes and methods of a parent class and then extend the new class with additional attributes and methods.

  • 15.1 Relational Databases

    29/09/2016 Duração: 15min

    We look at the history of database systems, learn the terminology of database systems, and review some of the common database systems that are in use.

  • 15.2 Single Table SQL

    29/09/2016 Duração: 10min

    We learn about how we can use Structured Query Language (SQL) to insert (create), read, update, and delete data in a single database table.

  • 15.3 Building a Relational Model

    29/09/2016 Duração: 08min

    We look at how we can take the various data elements that will be modeled in an application and distribute them across several tables efficiently. We learn about the basic rules of database design.

  • 15.4 Database Key Types

    29/09/2016 Duração: 04min

    We look at primary keys, logical keys and foreign keys. We look at how foreign keys are represented in the database.

  • 15.5 Representing Relationships in Database Tables

    29/09/2016 Duração: 11min

    We look at how we map a logical database model to a physical database model by adding columns and constraints to model the table-to-table relationships.

  • 15.6 Multi-Table Retrieval using JOIN

    28/09/2016 Duração: 10min

    We look at how to reconstruct complete views of the data when data is properly distributed across multiple tables and connected via foreign keys. We learn the JOIN operation and ON clause in SQL.

  • 15.7 Many-to-Many Relationships

    28/09/2016 Duração: 13min

    We look at how to build a connector table to represent many-to-many relationships such as students and courses in database tables. We also learn about composite primary keys.

    28/09/2016 Duração: 06min

    In this assignment we make use of the Google GeoCoding API to look up addresses, store the data in a database and then use Google Maps to visualize the data.

  • 16.2 Building a Web Search Engine

    28/09/2016 Duração: 11min

    We build a web crawler that retrieves web pages and links from those pages an copies the pages into the database. Once we have retrieved our web data we run a simple Page Rank algorithm on the data and visualize the results.
