Key Values

NemesisDB uses the key-value nature of JSON to manage data.

If we have this JSON:

{
  "age":50,
  "cars":["BMW", "Ford"],
  "address":
  {
    "city":"Paris",
    "country":"France"
  }
}

age, cars and address are keys:

• age has a number value
• cars has an array value
• address has an object value

This is how NemesisDB treats the data when stored:

• age is mapped to 50
• cars is mapped to ["BMW", "Ford"]
• address is mapped to {"city":"Paris","country":"France"}

Set

To store the above, you can use the KV_SET command:

{
  "KV_SET":
  {
    "keys":
    {
      "age":50,
      "cars":["BMW", "Ford"],
      "address":
      {
        "city":"Paris",
        "country":"France"
      }
    }
  }
}

• keys contains the keys and values to store

Get

To get the above keys:

{
  "KV_GET":
  {
    "keys":["age", "cars", "address"]
  }
}

• keys an array of keys to retrieve

This returns:

{
  "KV_GET_RSP":
  {
    "keys":
    {
      "age":50,
      "cars":["BMW", "Ford"],
      "address":
      {
        "city":"Paris",
        "country":"France"
      }
    }
  }
}
