Making small edits overwrite only the parts of the file that change, reducing write time and wear on SSD drives. The application loads only the data it needs, rather than reading the entire file and holding a complete parse in memory. Reading and writing from an SQLite database is faster than reading and writing files directly from disk. There are many advantages of using SQLite as an application file format: In contrast to most other database management systems, SQLite is not a client-server database engine but is embedded into the end program. SQLite is a relational database management system (RDBMS) that is contained in a C library. Below are the topics covered in this blog: In this blog on “SQLite Browser”, we will learn everything you need to know about this browser. It is for developers wanting to create databases, search, and edit data. In combination with Apple’s controller classes and key-value binding compatible view widgets, you can implement a complete MVC architecture with very little code.DB Browser for SQLite is a high quality, open-source tool to design, create, and edit database files compatible with SQLite. However, you may still want to learn Core Data for use as an object graph management framework. ![]() If you want a relational database, use SQLite (directly or via one of the Objective-C wrappers such as FMDB), or a relational database server. Thus, there is not really any conflict between using Core Data or SQLite directly. Conversely, you should not rely on being able to read Core Data’s SQLite data stores with other SQLite tools the schema is an implementation detail that may change. The BaseTen framework is also an implementation of the Core Data API using PostgreSQL as a backend.īecause Core Data is not intended to be an ORM for SQLite, it cannot read arbitrary SQLite schema. If you’re interested in how Core Data is implemented on an SQLite backend, you might want to check out OmniGroup’s OmniDataObjects framework, an open source implementation of a subset of the Core Data API. As others have pointed out, Core Data can also use XML or a binary format or a user-written atomic format as a backend (though these options require that the entire object graph fit into memory). It could have been implemented using a different relational database or even a non-relational database such as CouchDB. To implement its graph management, Core Data happens to use SQLite as a disk store. Core Data is thus an ideal framework for building the “model” component of an MVC architecture. keeping forward and backward links consistent when objects are added/removed to/from a relationship). Core Data also manages constraints on properties and relationships and maintains reference integrity (e.g. ![]() It manages a potentially very large graph of object instances, allowing an app to work with a graph that would not entirely fit into memory by faulting objects in and out of memory as necessary. It is, in fact, an object graph management framework. Although Core Data is a descendant of Apple’s Enterprise Object Framework, an object-relational mapper (ORM) that was/is tightly tied to a relational backend, Core Data is not an ORM. ![]()
