Under schemas section it will list down all the database schemas or different databases in the server. Database Navigator Maps is a graphical tool to visualize the database design. It is shown database tables, constraints and relationships or references in graphical notations. Database Navigator Maps can be used to manage your database as well. SQL Performance Monitors can be used to monitor and fine tune the database design. Transactions section shows Database Transactions and Global Transactions.

Select Schemas to Display
Expand the Schemas section to see the database you have already in the server. If it not listed your particular database you can add that database to navigator by using "Select Schemas to Display" option. Right click on the Schemas and select "Select Schemas to Display".

Create New Schema
If you want to create a new database or schema, right click on Schemas and select "New -> Schema". Specify a name for the new schema, whether it needs to add to displayed list of schemas and create as standard library. "Create in" is the system pool that you want to create your database in. "Text" is to discribe shortly your database for operator's purpose.

Building robust APIs with Node.js

Node.js is a popular open-source JavaScript runtime environment that allows developers to build scalable and high-performance web applications. One of the key strengths of Node.js is its ability to build APIs quickly and efficiently. APIs, or Application Programming Interfaces, allow different systems to communicate with each other, enabling data exchange and other operations. Building robust APIs with Node.js requires an understanding of RESTful architecture, which is a widely adopted standard for creating APIs. RESTful APIs provide a standardized way to expose data and functionality over the web using a set of HTTP methods such as GET, POST, PUT, and DELETE. To build a robust Node.js API, developers must choose an appropriate framework and set up a development environment. They should also handle errors and exceptions, implement authentication and authorization, and use middleware to enhance the functionality of the API. Writing test cases, documenting the API using tools such as Swa...

The Power of ChatGPT and Whisper Models

A Deep Dive into Natural Language Processing Natural Language Processing (NLP) has seen a significant boost in recent years due to advancements in artificial intelligence and machine learning. Two models that have shown remarkable success in NLP are ChatGPT and Whisper. In this article, we will delve into the power of these models and their applications in the field of NLP. ChatGPT is a transformer-based language model developed by OpenAI that uses unsupervised learning to predict the next word in a sentence based on the context of previous words. ChatGPT is a generative model that is trained on large datasets of text, such as books and articles, and can be fine-tuned for specific tasks, such as question-answering or dialogue generation. ChatGPT is known for its ability to produce human-like text, making it an ideal tool for applications such as chatbots, content creation, and language translation. Whisper, on the other hand, is a paraphrasing model developed by Google that is based on...
