Fast, reliable data access is crucial for AI-powered features, and the key to a great user experience. A cloud-only database is great for fixed-location apps with fast, reliable internet connectivity. But for apps at the edge, such as mobile or IoT apps, cloud-only databases are problematic; internet latency and outages can hamper AI responses, ruin the user experience, and lead to business downtime.\u00a0\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Embedded Database to the Rescue<\/span><\/h2>\n<p><span style=\"font-weight: 400\">Using an <\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Embedded_database\"><span style=\"font-weight: 400\">\uc784\ubca0\ub514\ub4dc \ub370\uc774\ud130\ubca0\uc774\uc2a4<\/span><\/a><span style=\"font-weight: 400\">, operating directly within an app on device, solves internet dependency issues. Apps access and save data locally versus in the cloud. The app becomes less reliant on the internet, faster, and more available.<\/span><\/p>\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/SQLite\"><span style=\"font-weight: 400\">SQLite<\/span><\/a><span style=\"font-weight: 400\"> is the most well-known embedded database, and might seem an obvious choice for mobile or IoT app developers. But being well-known does not make it the best option for AI applications at the edge. Read on to learn why.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">What Is SQLite?<\/span><\/h2>\n<p><span style=\"font-weight: 400\">SQLite is a lightweight, self-contained SQL database engine that operates as an in-process library embedded directly within the host application. It is open source and easy to use, making it a good option for freestanding or \u201c<\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Air_gap_(networking)\"><span style=\"font-weight: 400\">air-gapped<\/span><\/a><span style=\"font-weight: 400\">\u201d apps where data is saved and accessed locally without requiring a network connected database. This is what makes SQLite a popular choice for standalone applications that need to operate without internet connectivity or direct access to a cloud backend database.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Where Does SQLite Shine?<\/span><\/h2>\n<p><span style=\"font-weight: 400\">SQLite is great for apps designed to work in isolation \u2013 such as personal health monitors, notes organizers, or sketching apps \u2013 where there is a single user, data does not need to be shared, and the user experience begins with a relatively blank slate where data is collected.<\/span><\/p>\n<p><span style=\"font-weight: 400\">When the above criteria apply, developers can use SQLite in their mobile, desktop, and IoT applications to store personal information, logs, device readings, user-created content, and other sorts of data.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Because it eliminates the need for a separate connected database, SQLite also eliminates the latency and downtime that are common with internet-connected apps.<\/span><\/p>\n<p><span style=\"font-weight: 400\">With all this upside, it might seem that SQLite is an ideal solution for any edge computing app \u2013 including those with AI features \u2013 but it has limitations that developers need to know, as well as better alternatives.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">AI at the Edge<\/span><\/h2>\n<p><span style=\"font-weight: 400\">Enterprise-scale mobile and IoT apps are global in scope, support many users who share information, and require high guarantees of speed and uptime. <\/span><a href=\"https:\/\/blog.couchbase.com\/edge-computing-architecture-introduction\/\"><span style=\"font-weight: 400\">\uc5e3\uc9c0 \ucef4\ud4e8\ud305<\/span><\/a><span style=\"font-weight: 400\"> is an alternative architecture to cloud computing for apps where ultra-low latency and high availability are paramount requirements. The overarching goal of edge computing is to eliminate internet dependencies by moving data processing closer to applications by using edge data centers and embedded data storage directly on devices. It\u2019s important to note that edge computing does not replace the cloud for running apps; more accurately, it&#8217;s an architecture that extends data processing from cloud to edge.<\/span><\/p>\n<p><a href=\"https:\/\/thenewstack.io\/cloud-to-edge-ai-with-a-mobile-database-platform\/\"><span style=\"font-weight: 400\">\u201cEdge AI\u201d<\/span><\/a><span style=\"font-weight: 400\"> is a concept that includes AI processing into edge computing architectures. This involves running <\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Large_language_model\"><span style=\"font-weight: 400\">LLM<\/span><\/a><span style=\"font-weight: 400\"> alongside the database in each architectural layer from cloud to edge, including <\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Small_language_model\"><span style=\"font-weight: 400\">SLMs on-device<\/span><\/a><span style=\"font-weight: 400\">. These sorts of topologies bring the same guarantees of speed and uptime for apps to the AI models that power their features.<\/span><\/p>\n<p><span style=\"font-weight: 400\">SQLite, an embedded database, can run on edge devices and may seem like a good fit for an edge AI architecture. However, if your app requirements go beyond the simple ones described earlier, you may want to reconsider.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Top 5 Reasons SQLite Is Wrong for Edge AI<\/span><\/h2>\n<p><span style=\"font-weight: 400\">Achieving the edge AI architecture requires a database that can run in isolation and, critically, securely synchronize data between the cloud and other app clients, while integrating seamlessly with AI models wherever they are hosted.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Here are five reasons SQLite struggles in an edge AI architecture:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400\"><b>Inflexible data model:<\/b><span style=\"font-weight: 400\"> SQLite is relational and follows a rigid schema, which can make it a challenge to articulate the model requirements for your apps in an efficient and appropriate way. Because of this rigidity, doing something as simple as adding a new field to the database can require an update of the entire schema. This means a new release of your mobile app with an updated data schema will require expensive database schema migrations to be performed on app launch, adding to your app startup costs. SQLite\u2019s relational model also limits the data formats it can support, which in turn limits AI accuracy and context. GenAI requires a broad range of data formats, so the more the database can support, the better. An alternative is to use a NoSQL database that supports JSON document data storage, which can handle massive amounts of data in multiple formats \u2013 ideal for AI.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>No built-in data synchronization:<\/b><span style=\"font-weight: 400\"> For multi-user apps that go in and out of connectivity, data synchronization is what provides consistency for a great user experience \u2013 as well as the fastest, most accurate AI responses. Data sync also enhances security; if a user permission changes, data sync instantly reflects the change across the app ecosystem to ensure that no one accesses something they shouldn\u2019t. SQLite does not support data synchronization out of the box, developers must <\/span><a href=\"https:\/\/www.couchbase.com\/blog\/ko\/build-mobile-data-sync-solution\/\"><span style=\"font-weight: 400\">build their own solution<\/span><\/a><span style=\"font-weight: 400\"> or integrate with third-party solutions, complicating the architecture and stealing development focus away from the core app functionality.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>No enterprise-grade backend database:<\/b><span style=\"font-weight: 400\"> Even with local data storage, a mobile app still needs a backend database as a central aggregation point for data; this is how a distributed mobile app ecosystem remains scalable and performant. As such, a backend database server \u2013 often deployed in the cloud \u2013 is an important part of the edge AI architecture. SQLite does not offer a freestanding scalable database, it is solely an embedded database. In order to gain a scalable backend for apps using SQLite you must integrate with a third-party database server technology. This makes deployments more complex and maintenance and upgrades more time-consuming for developers.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>No enterprise-level security:<\/b><span style=\"font-weight: 400\"> When using synchronized and decentralized data storage, it\u2019s important to access, transmit, and store data securely. To cover this completely, you need to address authentication, data at rest, data in motion, and read\/write access control. SQLite does not natively support role-based access or data encryption. If stringent data security is important \u2013 as it certainly is for AI \u2013 developers must build their own security integrations leveraging third-party security extensions.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>No vector search:<\/b><span style=\"font-weight: 400\"> For GenAI features such as conversational chatbots, recommenders, or AI-assistants, vector search enables easy integration with LLMs (large language models) through techniques such as retrieval-augmented generation (RAG) where the current local vector data is passed along with prompts to provide better precision and context for LLM responses. SQLite does not support vector search, meaning it cannot be used for RAG-based features or semantic search on-device, completely collapsing the edge AI benefits.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400\">In short, when building and deploying enterprise-class, high-scale AI-powered applications at the edge, you will arguably face many development hurdles if you go with SQLite.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Couchbase Mobile: The Right Database for Edge AI<\/span><\/h2>\n<p><span style=\"font-weight: 400\">Don\u2019t lose time trying to develop around SQLite\u2019s shortcomings when building and deploying AI-powered apps at the edge.
