In case you have an in depth description of the software program you wish to construct you’ll be able to use it. However for a complete conversion of your design notes to one thing that’s simply ingestible by GPT-Engineer, this can be a logical path to take.

Right here is the immediate the writer used with ChatGPT-4 to generate a design doc:

Generate a top quality design doc that can be utilized by our mission crew to design the software program described under. It ought to be full and usable as the only design documentation to get our crew to finish our mission.

Easy key-value database engine written in Python utilizing solely customary library modules (besides these talked about under).

The fundamental interplay with the database engine when it’s operating ought to be by way of imported Python module with a transparent and concise library API.

There must also be a separate console that may be run to behave as a command line REPL for interacting with the database engine and databases.

Further strategies of interplay ought to embrace an API created with Quick API (exterior library).

Design specs:

A key-value database is a kind of NoSQL database that shops knowledge as a group of key-value pairs. In contrast to conventional relational databases, key-value databases don’t implement a inflexible schema, offering flexibility and scalability for sure use circumstances. Designing a key-value database entails contemplating a number of essential specs.

Instructions that ought to be accessible:
– connect with database
– delete database
– get key
– insert knowledge
– replace knowledge
– delete knowledge
– seek for existence of each keys and values

Knowledge Mannequin: Every file consists of a singular key and an related worth. The worth is usually a easy scalar worth or a fancy knowledge construction (corresponding to JSON or XML).

Key Construction: The important thing serves as the first identifier for every knowledge entry and should be distinctive inside the database. Keys may be alphanumeric strings, integers, and even composite keys (a number of values mixed to type a single key).

Worth Construction: The worth related to every key may be of any knowledge kind. It will possibly vary from fundamental knowledge sorts (strings, numbers, booleans) to extra complicated buildings like nested objects or arrays.

Efficiency and Caching: In-memory caching methods ought to be employed to hurry up learn operations and cut back latency.


And right here is the design doc that ChatGPT-4 produced:

## Overview
The primary purpose of this mission is to design and develop a light-weight key-value database engine written in Python, utilizing solely customary library modules, and FastAPI for the HTTP interface. The appliance will present the important options of a key-value database, together with connecting to the database, knowledge insertion, replace, deletion, and retrieval, together with search performance for keys and values.

The database will likely be interfaced by way of three strategies:
1. A Python module that may be imported by different Python packages.
2. A command line REPL console for guide interplay.
3. An API created with FastAPI for distant interactions.

## Parts
The database engine may have the next essential elements:

1. **Knowledge Retailer**: The precise storage for the key-value pairs. As a easy Python implementation, this could possibly be a dictionary the place keys are distinctive identifiers and values may be of any datatype. The information retailer ought to have environment friendly strategies for accessing, including, updating, and deleting knowledge.
2. **Database Engine**: The engine that gives the strategies to work together with the information retailer.
