Oracle as a Document Store {JSON} and Oracle SQLcl

JSON – it’s the new whiz bang.

JavaScript has taken off, and you don’t need to take my word for it.

Most popular topics on StackOverflow based on a 50,000 user survey in 2016.

And with JavaScript comes JSON. There are so many libraries on GitHub that are about turning data into really slick web and mobile applications. We have our own set of libraries available – have you heard of Oracle JET?

So JSON is here for awhile. What can you do with it? Well, you know what you can do already with the Oracle Database. What if you could harness the power of our database engine and our SQL layer, but apply that to all the JSON you have laying around?

That’s the core idea behind the Oracle Document Store. In 12c (12.1.0.2) you can store JSON in an Oracle table, and work with it as JSON vs text that you’d have to manipulate manually.

And one of the interfaces we provide for this is known as Simple Oracle Document Access (SODA). We provide both REST and Java implementations for doing SODA.

AND, we also provide support for SODA in Oracle SQLcl.

If you want to create a new collection of documents, you can simply use the SODA CREATE command.

Actually, if you want to do any sort of SODA work, SQLcl supports that.

pretty straightforward once you get used to thinking in terms of collections vs tables

When you create a collection in SODA, it actually goes and creates a table in your schema to hold it.

Did you know you can view BLOBs as text?

Let’s Go Back to the CLI

If you want to quickly create some collections, query them, update them, delete them, or whatever – the entire SODA api is available in SQLcl. I’m not going to demo all of it for you, but if you’re interested in SODA, just know that SQLcl is already and waiting to help you.

Let’s add to our SODA collection.

We have a new row in our Oracle table now.

Now let’s see what we have in there.

What's in there overall, how many, and maybe a quick query?

One of the concepts I found immediately alluring was the notion of ‘Query By Example’ (QBE). Here I can use a bit of JSON to tell SODA what I’m looking for in the collection.

Name - test. Value - starts with the text '@eatRaleigh'.

Name – test. Value – starts with the text ‘@eatRaleigh’.

For what it’s worth, I’ve downloaded my tweets and stored them in the Oracle Document Store for these examples.

I hope you have an idea now of what’s available to you.
