Machavity, where do you find c in this? That comment was about the first revision of your answer, which had C in it.Recently I was discussing with Peter Saverman whether it would be possible to take some database tables that look like this:.

Prefer visuals instead of text? Well, from an application development standpoint this type of scenario can be fairly common. In a database, it makes sense to divide Home and Car and Toy into separate tables. Sure, we could probably combine the latter two with some normalization, but imagine we will have many different types of entities that will be more difficult to normalize — sometimes it just makes sense to store this information separately.

Not to mention that performing analytical type queries across many rows of data will typically be much faster stored in this three table format. The three table layout, while organized from a database standpoint, might not be the best way to organize the data in an object-oriented application.

Usually in a transaction oriented application, we want our data to all be together as one entity. This is why NoSQL is all the rage among app developers. Reading the data into the app through multiple queries and mapping that data to objects is usually the first way you would try doing something like this. However, depending on many different variables, like the size of the data, the number of requests, the speed of the network, the hardware the app is running on, etc… mapping your data from multiple queries might not be the most efficient way to go.

See the update at the bottom of this post. This creates a problem if, for example, you want to have a column for your JSON string and a separate column for something like a foreign key in our case, HomeId. Or if you want to generate multiple JSON strings filtered on a foreign key.

Your individual scenario and results may vary. This solution was to solve a specific scenario in a specific environment. Is it the right way to go about solving your performance problems all of the time? But offloading these transformations onto SQL Server is an option to keep in mind. This solution recommended by Jovan Popovic is even easier than above.

Thanks for reading.

I would like to create one JSON object, that contains the multiple arrays each with several pieces of data. An object called cars, containing multiple arrays each for a different make of car. In each array would be the model of car along with some other types of data e. If the JSON is assigned to a variable called data, then accessing it would be like the following:.

For example, this is an array in JavaScript:. Note the absence of a variable or a semicolon. Arrays and objects can be used together to represent more complex collections of data, such as:. This Array contains a number of objects representing books, Each object has several keys, one of which is "authors", which is another array. Objects and arrays are typically top-level parts of a JSON data structure even though this is not required and can be used to create a large number of data structures.

For the example from Mark Linus answer:. To do the opposite, convert a JSON object into a JavaScript object this is called parsingyou would use the parse method.
