SQLite features and specs

• Zero Configuration
  SQLite does not require any server setup or configuration, allowing for easy integration and deployment in applications.
• Lightweight
  It is extremely lightweight, with a small footprint, making it ideal for embedded systems and mobile applications.
• Self-Contained
  SQLite is self-contained, meaning it has minimal external dependencies, which simplifies its distribution and usage.
• File-Based Storage
  Data is stored in a single file, which makes it easy to manage and transfer databases as simple files.
• ACID Compliance
  SQLite supports Atomicity, Consistency, Isolation, and Durability (ACID) properties, ensuring reliable transactions.
• Cross-Platform
  SQLite is available on numerous platforms, including Windows, MacOS, Linux, iOS, and Android, providing a broad compatibility range.
• Public Domain
  SQLite operates under the public domain, allowing for unrestricted use in commercial and non-commercial applications.

Possible disadvantages of SQLite

• Limited Scalability
  SQLite is not designed to handle high levels of concurrency and large-scale databases, making it less suitable for large, high-traffic applications.
• Write Performance
  Write operations can be slower compared to server-based databases, especially under heavy write loads.
• Lack of Certain Features
  SQLite lacks some advanced features offered by other RDBMS like stored procedures, user-defined functions, and full-text search indexing.
• Security
  As SQLite is file-based, it might lack some of the security features present in server-based databases, such as sophisticated access control.
• Concurrency
  SQLite uses a locking mechanism to control access to the database, which can lead to contention and performance bottlenecks in highly concurrent environments.
• Backup and Restore
  While it's straightforward to copy SQLite database files, it lacks the advanced backup and restore features found in more complex RDBMS.

UnQLite features and specs

• Lightweight
  UnQLite is an embedded NoSQL database engine designed to be lightweight, making it ideal for applications with limited resources or those that require a simple, efficient database solution.
• Single File Storage
  The entire database is stored in a single file, which simplifies deployment and management, and reduces the overhead associated with multiple files.
• Zero Configuration
  UnQLite requires no configuration, allowing developers to easily integrate it into their applications without having to deal with complex setup procedures.
• Embedded JSON Document Store
  It includes a built-in JSON document store which allows for storing and querying JSON documents efficiently, making it suitable for a variety of applications, especially those that handle JSON data.
• Support for Key/Value Storage
  UnQLite supports key/value storage, providing flexibility in data modeling by allowing developers to choose between a document-oriented or a key/value store.
• Cross-Platform
  UnQLite can be used across different operating systems, offering the flexibility to develop applications in a variety of environments.

Possible disadvantages of UnQLite

• Limited Scalability
  UnQLite, being an embedded database, may not scale well for extremely large datasets or highly concurrent environments compared to other distributed database systems.
• Lack of Advanced Features
  UnQLite lacks some advanced database features found in other DBMS such as complex transactions, extensive query capabilities, and built-in replication.
• Community and Ecosystem
  The community and ecosystem around UnQLite are not as large or active as those around more popular databases, which might limit the availability of third-party tools and resources.
• Limited Documentation
  While UnQLite has basic documentation, it may not be as comprehensive as that of other more established database systems, potentially hindering new users.
• SQL Incompatibility
  Unlike SQL databases, UnQLite uses its own query language, which might be unfamiliar to developers accustomed to SQL, requiring additional learning and adjustments.
