⚡Overview

In the DB UI (Database user interface) is a custom web-based interface that allows users to interact with PostgreSQL databases in real time through a streamlined, browser-accessible environment. Designed as a lightweight alternative to traditional database clients, it simplifies tasks like executing SQL queries, reviewing results, and diagnosing issues without the need for complex desktop tools. Built with developers, analysts, and support teams in mind, it provides a fast, user-friendly way to perform ad-hoc queries, data lookups, and live diagnostics especially in internal environments. The UI supports secure PostgreSQL connections and is extendable to integrate with role-based access controls and existing infrastructure.

⚡Introduction

DB UI is a custom, web-based tool that streamlines interactions with PostgreSQL databases. Tailored for developers, analysts, and support teams, it provides a clean and intuitive interface to run SQL queries, inspect results, and troubleshoot issues all directly from a browser. By eliminating the need for complex desktop clients, it enables fast, secure, and efficient access to live data, making it ideal for internal diagnostics, ad-hoc queries, and real-time operational support.

📊Data Viewer Form

How to use the Data Viewer Form?
NOTE:

Before open the DB UI, users must select the region from navbar

  • The user may enter a specific Data base name in the designated field or slot.
  • The user may enter a specific Table and Column name in the designated field or slot.
  • The user can enter sql commands in the terminal.

Here, users can begin by selecting the appropriate server name, followed by the desired table and column names. Once the context is set, users can enter a custom SQL command directly into the terminal interface. This allows for real-time interaction with the PostgreSQL database executing queries, retrieving data, or performing updates as needed. The interface simplifies query handling and ensures that users can efficiently validate or troubleshoot data without switching to external tools.

💻Terminal Interface

In the DB UI, when users execute commands, a dedicated terminal interface appears, allowing them to enter and run SQL queries directly. Upon execution, the system processes the input and returns the results in a structured tabular format, making it easier for users to read, interpret, and analyze the data. This interactive setup enables real-time database interaction and simplifies query testing, data retrieval, and debugging.

SQL Terminal Process:
• Select the appropriate server name
• Choose the desired table name and column name
• Enter a custom SQL command in the terminal interface
• Execute the command to interact in real time with the PostgreSQL database
• Perform actions such as querying, retrieving, or updating data
• The terminal simplifies query handling within the browser
• Helps users validate or troubleshoot without using external tools

🔍Column Selection & Data Retrieval

If a user wants to view data for a specific column, they can first select the database, which will then display the available tables. After choosing a table, users can select one or more columns to retrieve data. Once a column is selected, the corresponding data is automatically displayed, and multiple columns can be selected as needed for detailed queries.

Multi-Column Selection:

Users can add multiple columns to the query, allowing flexible and customized data retrieval based on the selected table.

Database Selection:

Choose the target database from available options

Table Selection:

Select the desired table from the database

Column Selection:

Pick one or more columns for data retrieval

Data Display:

View the automatically displayed results

🎯Final Output & Results

Final Output:

After executing a SQL command through the DB UI terminal, the system returns the output in a structured tabular format. Users can filter results by columns, refresh the data, and switch between regions if required. This enables quick data validation, effective monitoring, and faster troubleshooting across different environments.

Key Features of Output:
  • Structured Tabular Format: Results are displayed in an organized, easy-to-read table
  • Column Filtering: Filter results by specific columns for focused analysis
  • Data Refresh: Real-time data updates with refresh functionality
  • Region Switching: Switch between different database regions as needed
  • Quick Validation: Immediate data validation capabilities
  • Effective Monitoring: Continuous monitoring of database states
  • Fast Troubleshooting: Rapid issue identification and resolution
  • Multi-Environment Support: Works across different environments seamlessly
Sample SQL Output:
