+Welcome
+-------
+
+This is a presentation about NoSQL for cartographers.
+
+Why me?
+-------
+
+- 2008: first paid software job.
+- 2012: graduated Computing Science.
+- 2014-2016: Amazon Web Services.
+- 2016+: Uber.
+- Using SQL and NoSQL at dayjob.
+
+What is a server?
+-----------------
+
+SQL
+---
+
+- Invented > 50 years ago.
+- Technologies differ, concepts are the same.
+
+Power and limitation of SQL
+---------------------------
+
+Let's model a house on a piece of land.
+
+- There will be always a piece of land under a house.
+- SQL says you can enforce this.
+
+**They must be on the same server to enforce this constraint.**
+
+If constraint cannot be created, it's not SQL.
+If it's SQL, all houses and all areas must be on the same server.
+
+Get a big database
+------------------
+
+$30 to about a $1M. Show graphics.
+
+Alternatives
+============
+
+Cat videos do not require topology. But we still need storage -- No SQL!
+
+Like-SQL
+--------
+
+Forego some SQL constraints, but use the same (/similar) language:
+- No uniqueness constraints.
+- No foreign keys.
+- ... many more restrictions.
+
+Hive:
+```
+SELECT a.foo FROM invites a WHERE a.ds='2008-08-15';
+```
+
+
+Key-Value: fast & small
+-----------------------
+
+DynamoDB, Cassandra. Some have their language, some don't.
+
+DynamoDB:
+```
+table = dynamodb.create_table(
+    TableName='users',
+    KeySchema=[
+        { 'AttributeName': 'username', 'KeyType': 'HASH' },
+        { 'AttributeName': 'last_name', 'KeyType': 'RANGE' }
+    ],
+)
+```
+
+Cassandra:
+```
+INSERT INTO monkeys (type, family, common_name, conservation_status)
+VALUES ('New World Monkey', 'Cebidae', 'white-headed capuchin', 'Least concern');
+```
+
+Key-Value: slow & big
