Everybody building a web application with a modern framework, is already probably using an ORM<\/a> (Object-Relational Mapping).\u00a0 Most frameworks include one out of the box.\u00a0 But digging deeper into the subject, ORMs do vary from each other, and some cases, very significantly.<\/p>\n

Most variations are coming from two main approaches: Active Record<\/a> and Data Mapper<\/a>.\u00a0 I’ve heard the terms for a long time, but today decided to look into the meaning and the actual difference.<\/p>\n

The two approaches seem very similar.\u00a0 The difference is described in a multitude of articles online.\u00a0 I particularly liked this one<\/a>.\u00a0 In essence, Active Record is a better choice for simpler, CRUD-based applications.\u00a0 Data Mapper, on the other hand, is better for domain-specific applications, as it provides another level of abstraction between the domain objects and the persistence layer.<\/p>\n

Most of my work these days is done with CakePHP framework<\/a>, which I now thought uses the Active Record pattern.\u00a0 But it turns out that CakePHP ORM<\/a> so powerful, because it’s more than just one of those:<\/p>\n

The CakePHP ORM borrows ideas and concepts from both ActiveRecord and Datamapper patterns. It aims to create a hybrid implementation that combines aspects of both patterns to create a fast, simple to use ORM.<\/p><\/blockquote>\n

It looks like I need to do some learning and dig deeper into the subject.\u00a0 Pointers are welcome.<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
