Join William Lyon for an in-depth discussion in this video Overview of database creation, part of Database Clinic: Neo4J.
- All right, it's time for our first challenge.…Lao Tzu said it best,…the journey of a thousand miles begins with one step.…The first step in our journey is creating a database.…Databases store a combination…of specifically formatted information…and open ended information.…Different database tools store that information…in unique ways.…Flat files use a table,…SQL databases use the relational model,…and NoSQL databases use a key value model.…
Regardless of how they store that data,…many tools are optimized so that if the database knows…that a certain piece of information…will always be in a specific format,…for example a date, an amount of money,…or a geographical location,…it can treat that information more efficiently.…An important part of creating a database…is understanding the kinds of data that you need to store.…Once your database is setup…and knows what information to expect,…it's time to add that information in.…
Databases are populated in several different ways.…They can be populated by hand.…For example, consumer polls are conducted face to face…
