![]() ![]() They are likely not going to perform better when very complex queries are involved.Learning how to use ORM tools can be time consuming.You write less code when using ORM tools than with SQL.ORM tools are built to eliminate the possibility of SQL injection attacks. Handles the logic required to interact with databases.It speeds up development time for teams.Here are some of the advantages of using an ORM tool: Now let's discuss some of the advantages and disadvantages of using ORM tools. Base One Foundation Component Library (BFC)īFC is a framework for creating networked database applications with Visual Studio and DBMS software from Microsoft, Oracle, IBM, Sybase, and MySQL This tool doesn't do most of the things an ORM tool would do like SQL generation, caching results, lazy loading, and so on. It is mainly used to map queries to objects. NHibernate is an open source object relational mapper with tons of plugins and tools to make development easier and faster. It supports SQL, SQLite, MySQL, PostgreSQL, and Azure Cosmos DB. Entity FrameworkĮntity Framework is a multi-database object-database mapper. ![]() RedBeanPHP is a zero config object relational mapper. Qcodo provides different commands that can be run in the terminal to interact with databases. CakePHPĬakePHP provides two object types: repositories which give you access to a collection of data and entities which represents individual records of data. Laravel comes with an object relational manager called Eloquent which makes interaction with databases easier. SQLAlchemy provides persistence patterns designed for efficient and high-performing database access. ![]() SQLObject is an object relational manager that provides an object interface to your database. Web2py is an open source full-stack Python framework for building fast, scalable, secure, and data-driven web applications. Djangoĭjango is a great tool for building web applications rapidly. The data can be transformed into either relational data or XML elements. You can use Oracle TopLink to build high-performance applications that store persistent data. You can also use this tool to build type safe SQL queries. JOOQ generates Java code from data stored in a database. EclipseLinkĮclipseLink is an open source Java persistence solution for relational, XML, and database web services. It can be used as a stand-alone POJO (plain old Java object) persistence layer. Apache OpenJPAĪpache OpenJPA is also a Java persistence tool. Hibernate is highly performant and is also scalable. Hibernate enables developers to write data persistent classes following OOP concepts like inheritance, polymorphism, association, composition. NET development: Popular ORM Tools for Java 1. Here are some of the most popular for Java, Python, PHP, and. Most OOP languages have a variety of ORM tools that you can choose from. ORM tools can generate methods like the one in the last example. Note that every ORM tool is built differently so the methods are never the same, but the general purpose is similar. So the code above does the same as the SQL query. On the other hand, an ORM tool can do the same query as above with simpler methods. Using the WHERE clause, we specified that the information should be from a user with an id of 20. The code above returns information about a user - name, email, country, and phone_number - from a table called users. Here's an example of SQL code that retrieves information about a particular user from a database: "SELECT id, name, email, country, phone_number FROM users WHERE id = 20" ![]() So instead of creating your own ORM software from scratch, you can make use of these tools. What is an ORM Tool?Īn ORM tool is software designed to help OOP developers interact with relational databases. While using SQL for this purpose isn't necessarily a bad idea, the ORM and ORM tools help simplify the interaction between relational databases and different OOP languages. By design, you use SQL for performing these operations in relational databases. When interacting with a database using OOP languages, you'll have to perform different operations like creating, reading, updating, and deleting (CRUD) data from a database. Put another way, you can see the ORM as the layer that connects object oriented programming (OOP) to relational databases. Object Relational Mapping (ORM) is a technique used in creating a "bridge" between object-oriented programs and, in most cases, relational databases.
