Restoring data from pg_dump snapshot

series: In depth guide on creating and restoring back-ups on PostgreSQL
---

**TL;DR**: _Building on the previous post about capturing "snapshots" of PostgreSQL databases and their benefits for testing and debugging, this post dives into the practical side: how to leverage these snapshots and restore your database to a specific state with ease._


## Prerequisite

1. For linux OS, we need to add some environment variables on our rc files: `bashrc` or `zshrc`:

```bash
export PGHOST=${postgres_host}
export PGPORT=${postgres_port}
export PGUSER=${postgres_username}
export PGPASSWORD=${postgres_password}
```

We'll be dependent on the values of these environment variables to be able to effectively use the next steps.

2. If your dev environment is based on container technologies like docker, make sure the container with the database is running.
3. Since we are restoring the data of an existing database, drop the database on the postgre server if it exists otherwise create the database.

# Bash script for restoring snapshot data

Create a `.sh` file on the directory where your service's repository is stored and then paste the contents of the script below. 

I'll leave some comments to further explain the details of what the script does so that users can understand it better.


```bash
#!/usr/bin/bash

# HOW TO USE?
# 1. this must be used after the pg_dump data has been successfully created.
# 2. update the value of the "parent_directory".
# 3. also update the value of the "target_database" array.

# ---
# this variables refers to the directory level where the "database_dump" folder is located
parent_directory="home/development-environments/service-1"

cd ~/
cd "$parent_directory/database_dump"

# ---
# list your databases that you want to have a restore here.
# This variable refers to the databases that you want to restore. Make sure that all the database you wish to restore are all newly created ones.
target_database=("database_1" "database_2" "database_3")

# ---
# iterates throught the databases to be restored. Then prints a message to indicate if the procedure was a success or fail.
for database_name in "${target_database[@]}"; 
do
  psql -h $PGHOST -U $PGUSER "$database_name" < "$database_name.sql"

  if [ $? -eq 0 ]; then
   echo "${database_name} data has been restored successfully."
  else
    echo "Error: Data restoration attempt for ${database_name} has failed."
  fi
done

```

# Conclusion 

Restoring data from a single .sql database snapshot is a straightforward process. However, when dealing with multiple snapshots, automation becomes essential for efficiency and consistency. To optimize the restoration of multiple snapshots, consider utilizing Bash scripts. These scripts automate the process, significantly reducing manual effort and potential errors.

When paired with the pg_dump method for creating database snapshots, the restoration procedure via bash scripts create a powerful combination that empowers developers to focus on core tasks while streamlining testing and debugging experiences.

MVP Design Pattern in C#
Tags: csharp
Published: 2023-12-26 07:54:41

The Model-View-Presenter (MVP) design pattern is a popular architectural pattern in C# development that separates the application's logic into three distinct components: the model, the view, and the presenter.

The model represents the application's data and business logic. It encapsulates data, performs data manipulation, and communicates with other components or services. The model is independent of the view and presenter, ensuring that the business logic remains decoupled from the user interface.

The view is responsible for displaying the user interface to the user. It gathers user input and interacts with the presenter to update or retrieve data from the model. The view should be passive and only responsible for rendering user interface elements and notifying the presenter of user actions.

The presenter acts as an intermediary between the model and the view. It receives user actions from the view and updates the model accordingly. It also retrieves data from the model and updates the view to reflect any changes. The presenter is responsible for coordinating the interactions between the model and the view.

Implementing the MVP design pattern in C# has several benefits. Firstly, it improves the modularity and maintainability of the codebase by separating concerns into distinct components. This separation makes it easier to update or replace individual components without impacting the others.

Secondly, MVP simplifies the testing process. Since the model, view, and presenter are decoupled, each component can be tested independently. This allows for more focused and targeted testing, ensuring that bugs or issues are localized and easier to pinpoint.

Lastly, MVP promotes reusability and scalability. By separating the user interface from the underlying logic, the codebase becomes more adaptable and flexible. This enables developers to reuse the presenter and model components across different views or adapt them to different user interfaces.

Overall, the MVP design pattern is a powerful tool for C# developers looking to build cleaner, more maintainable, and testable applications. By separating concerns and providing clear boundaries between components, MVP helps create a more scalable and reusable codebase.

Two Sum
Published: 2023-12-26 07:36:51

Given an array of integer nums and an integer target, return indices of the two numbers such that they add up to the target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

You can return the answer in any order.

Example 1:

Input: nums = [2,7,11,15], target = 9
Output: [0,1]
Explanation: Because nums[0] + nums[1] == 9, we return [0, 1].
Example 2:

Input: nums = [3,2,4], target = 6
Output: [1,2]
Example 3:

Input: nums = [3,3], target = 6
Output: [0,1]


```
class Solution {
public:
    vector<int> twoSum(vector<int>& nums, int target) {
        vector<int> ans;
        unordered_map<int, int>mpp;
        for(int i=0;i<nums.size();i++){
            if(mpp.find(target - nums[i])!= mpp.end()){
                ans.push_back(mpp[target-nums[i]]);
                ans.push_back(i);
                return ans;
            }
            mpp[nums[i]] =i;
        }
        return ans;
      
    }
}

API Vs Web Scraping: Online Data Extraction Tools
Tags: api, webscraping, webdev, database
Published: 2023-12-26 07:10:43

With the never-ending demand for data extraction and its tools, an increase in the amount of data that needs to be researched, analyzed, and extracted has been observed. Two major data-extracting tools that have been the talk of the town are API (application programming interface) scraping and web scraping. Both tools are believed to be two sides of the same coin, with some choosing API scraping over web scraping or vice versa.
Through this article, we will put both theories to the test and determine the better data extractor among these two.

## API Scraping: 
API Scraping refers to extracting and accessing data from different websites or operating systems using [APIs](https://newsdata.io/blog/useful-apis-for-developers/). These tools present the data in a machine-readable format, making it an efficient and convenient source. The working of API scraping consists of four main steps: initial request, authentication, acquiring data, and data storage.

## Web scraping: 
[Web scraping](https://newsdata.io/blog/web-scraping/) refers to the process of extracting data from a given website or operating system, either manually or by using software tools. The software tools used to extract data are known as web scrapers. The work of web scraping consists of three main steps: requesting data, data parsing, and data storage.
While both API and web scraping have their benefits and drawbacks, labeling either of them as the absolute best is a tough task. Especially now that there is an uprise of yet another data extraction tool that has the benefits of API and web scraping combined.

## Web Scraping API:
A web scraping API is a tool that extracts data from various platforms using API calls. This tool can work its way through several difficulties faced by API and web scraping tools. The working of a web scraping API consists of three main steps: data request, processing of the data, and storage.
Furthermore, we discussed the top 5 web scraping API tools on the market at present, which include Charles Proxy, RESTful Clients (Node.js), and HTTPRequester (Java).
Read this blog for detailed information: https://newsdata.io/blog/api-vs-web-scraping/

Whatever differences both tools might have, they are equally popular among their peers. And to make things even more interesting, the Web Scraping API is giving the other two tools a run for their money. In a sense, it can be said that Web API scraping was designed in such a way that it not only overcomes whatever difficulty is being faced by API and Web scraping tools but also ensures increased efficiency.
