Retrieval

The data was retrieved by Shrey and Matthew through an application from the Crunchbase Website for the API service. The data took about a month to come in due to a lack of response from Crunchbase itself. Eventually, they gave us basic access.

Content

The snapshot contained 2 .tar.qz files, which were extracted into 181/crunchbase using the command

tar -zxvf file.tar.gz

The csv files (organizations.csv and people.csv) were copied for access to:

E:\McNair\Projects\Accelerators\Crunchbase Snapshot

The files (size in bytes) and their contents are

Changing MYSQL to PostgreSQL

The SQL files were generated in MySQL. We need to convert them to PostgreSQL. See: https://en.wikibooks.org/wiki/Converting_MySQL_to_PostgreSQL and http://stackoverflow.com/questions/1942586/comparison-of-database-column-types-in-mysql-postgresql-and-sqlite-cross-map

The key changes are:

MYSQL          POSTGRESQL
-----          ----------
LOCK           --comment out as no need but LOCK [ TABLE ] [ ONLY ] name [ * ] [, ...] [ IN lockmode MODE ] [ NOWAIT ]
UNLOCK         --comment out
decimal(x,y)   real (might work as is)
datetime       timestamp
KEY            --comment out as no need but FOREIGN KEY ( column_name [, ... ] ) REFERENCES reftable [ ( refcolumn [, ... ] ) ]
