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.

Realm.io features and specs

  • Easy Integration
    Realm is designed to be easy to set up and integrate into existing projects, with straightforward APIs and comprehensive documentation.
  • Performance
    Realm provides high performance with minimal overhead. It's faster than many traditional databases for many use cases, especially with large datasets and complex queries.
  • Cross-Platform Support
    Realm supports multiple platforms including iOS, Android, and React Native, allowing for easy cross-platform development.
  • Real-Time Data Sync
    Realm offers real-time synchronization of data between devices and a server, ensuring consistency and enabling collaborative features.
  • Rich Data Types
    Realm supports complex data types such as lists and objects, making it more flexible for various types of applications.

Possible disadvantages of Realm.io

  • Learning Curve
    Despite extensive documentation, there can be a learning curve for developers new to Realm, particularly if they are accustomed to traditional SQL databases.
  • Storage Size
    Realm databases can become large quickly, especially if not properly managed, potentially impacting app performance and storage costs.
  • Limited Query Language
    While powerful, Realm's query language isn't as mature or feature-rich as SQL, which might limit some advanced querying needs.
  • Tooling
    The tooling ecosystem for Realm is not as extensive as those for more established databases like SQLite or MongoDB, which could impact developer productivity.
  • Vendor Lock-In
    Using Realm might lead to vendor lock-in, as migrating away from it to another database system can be complex and time-consuming.

  • Can I have my Lightroom catalogue pointing at two sources...?
    Yes. A Lightroom catalog file is, after all, just a SQLite database. (Srsly, make a copy of your catalog file, rename it whatever.sqlite and use your favorite SQLite GUI to rip it open and look at the tables and fields). It's just storing the pathame to the RAW file for that file's record in the database. Source: almost 2 years ago
  • Building a database to search Excel files
    I use visidata with a playback script I recorded to open the sheet to a specific Excel tab, add a column, save the sheet as a csv file. Then I have a sqlite script that takes the csv file and puts it in a database, partitioned by monthYear. Source: about 2 years ago

  • "Managing" a SQLite Database with J (Part 2)
    With this in mind, I wrote a few versions of this post, but I hated them all. Then I realized that jodliterate PDF documents mostly do what I want. So, instead of rewriting MirrorXref.pdf, I will make a few comments about jodliterate group documents in general. If you're interested in using SQLite with J, download the self-contained GitHub files MirrorXref.ijs and MirrorXref.pdf and have a look. - Source: dev.to / over 2 years ago
  • "Managing" a SQLite Database with J (Part 1)
    SQLite, by many estimates, is the most widely deployed SQL database system on Earth. It's everywhere. It's in your phone, your laptop, your cameras, your car, your cloud, and your breakfast cereal. SQLite's global triumph is a gratifying testament to the virtues of technical excellence and the philosophy of "less is more.". - Source: dev.to / over 2 years ago

  • I built a WebComponents-based framework
    Looks really cool, I like to make very minimalistic dependency choices for the web apps I work on. Web Components look interesting and it's great to see frameworks that build upon it and provide features that are currently missing from it. When I landed on the page I remembered another Realm framework I used a lot long time ago. https://realm.io has the same name and the logo looks very similar too.

  • Looking for android java developer mentor
    I would focus on Kotlin instead of Java, there's really no point in sticking to Java at this point. And when it comes to databases, some local ones that are pretty easy to get into are Realm and ObjectBox, SQLite can definitely be a bit overwhelming at the beginning. Source: almost 2 years ago
