However, you might not yet be familiar with its counterpart: the ILIKE operator. To learn, visit .If youвЂ™ve done any pattern matching in your PostgreSQL queries, youвЂ™ve probably become acquainted with the LIKE operator.

Unlike the LIKE function, string matching is case-insensitive. TypeScript is an extension to JavaScript that adds a strict type system. Allows matching of strings based on comparison with a pattern. TypeORM uses TypeScript exclusive features for defining your entities, and although it's not required to use TypeORM, it makes it much easier to do so. You can then define properties in these classes that map to the respective columns in the database, and even include custom methods in the entities that manipulate them.ДЇor starters, you'll want to have TypeScript and TypeORM installed. Data Mapper allows you to represent tables and other data as Entity classes. We'll be demonstrating examples with both Data Mapper and Active record patterns.Д«oth the Data Mapper and Active Record patterns are supported by TypeORM, and we'll cover the former first.

This allows ORMs to simplify your logic that manipulates data in the database. ORM stands for object-relational-mapping and allows you to interact with your database using objects from your programming language's type system rather than hand writing queries. This works fine, and will be perfect for many applications, but one may also choose to opt for using an ORM instead.
