Connecting ASP.NET Core Site to Master and Slave using POME

ASP.NET Core is a popular programming language for building web applications. One common requirement in web development is the ability to connect to multiple databases simultaneously, such as a master and slave database. In this article, we will explore how to achieve this using POME ( Object Engine).

POME is a lightweight and flexible ORM (Object-Relational Mapping) framework for .NET. It provides a and intuitive way to map database tables to .NET objects, allowing developers to with databases using object-oriented programming techniques.

Step 1: Setting up the ASP.NET Core Site

Before we can connect to the master and slave databases, we need to set up our ASP.NET Core site. Start by creating a new ASP.NET Core project or opening an existing one.

Next, open the appsettings.json file and add the strings for both the master and slave databases. The connection strings should be placed under the ConnectionStrings section, like this:

  "ConnectionStrings": {
    "MasterConnection": "your_master_connection_string",
    "SlaveConnection": "your_slave_connection_string"

Make sure to replace your_master_connection_string and your_slave_connection_string with the actual connection strings for your databases.

Step 2: Configuring POME

Now that we have set up our ASP.NET Core site, we can POME to connect to the master and slave databases. Open the Startup.cs file and locate the ConfigureServices method.

Inside the ConfigureServices method, add the following code to configure POME:

services.AddPome(options =>

This code configures POME to use the connection strings specified in the appsettings.json file. The UseConnection method is used to specify the connection string for the master database, while the UseSlaveConnection method is used to specify the connection string for the slave database.

Step 3: Using POME in Your Code

With POME configured, you can now use it in your code to interact with the master and slave databases. POME provides a set of APIs for performing CRUD (Create, Read, Update, ) operations on database tables.

Here's an of how to retrieve data from the master database:

In this example, we create a new instance of the PomeContext class, represents the database context. We then use the Query method to retrieve all customers from the master database and store them in a list.

Similarly, you can retrieve data from the slave database using the QuerySlave method:

In this example, we use the QuerySlave method to retrieve all products from the slave database.


In this article, we have explored how to connect an ASP.NET Core site to both a master and slave database using POME. By following the steps outlined above, you can easily configure POME to connect to multiple databases and perform CRUD operations on them. POME provides a convenient and efficient way to work with databases in ASP.NET Core applications.

Remember to always handle exceptions and ensure proper error handling when working with databases. Additionally, make sure to optimize your database queries and consider using caching mechanisms to improve .
