Salesforce is easy to learn


- August 29, 2017

Apex is a programming language for Salesforce development that acts as a pure backend technology and was specially designed for the development of business applications.

Properties of Salesforce Apex

Apex is a strongly typed and object-oriented programming language. Its syntax is similar to Java and C #. The programming language is one of three Salesforce technologies alongside Lightning and Visualforce. Apex is used exclusively in backend development, which takes place entirely on the servers.

Apex takes a uniquely productive approach to creating function and logic: Developers can concentrate fully on the elements specific to an application, while all other elements are taken over by the platform. This significantly reduces the development effort

Salesforce Apex architecture

Apex is based on the model-view-controller model. Entries made by a user on the user interface trigger processes so that a controller makes changes to the data model. The changed data model is then displayed in the view.

Apex is responsible for the manipulation of the data model, while Visualforce takes over the representation in the view.

Benefits of Salesforce Apex

Integrated: With Apex, specific features of the platform can be used, for example DML (Data Manipulation Language) calls, Inline Salesforce Object Query Language (SOQL) and Salesforce Object Search Language (SOSL) queries, call loops to call multiple data records in bulk API calls.

In our individual Salesforce administrator training, we offer you training in the administrative area that is specially tailored to your requirements and that builds on your previous knowledge.

Easy to learn: The syntax is similar to that of Java, so many similar variables, expressions, and statements are used. Easy-to-understand syntax and semantics are used for new elements, resulting in efficient code.

Data-driven: Apex bundles multiple queries and DML calls within a unit of work on the server.

Strict: Apex is a strictly typed programming language that uses direct references between schema objects, such as object and field names.

Hosted: Operations are carried out entirely on the platform and controlled from there.

Multi-tenant: Apex, like the rest of the platform, runs in a multi-tenant environment. Any code that disregards the resulting limitations is displayed with an error message.

Automatically updated: If Salesforce updates are released, no code has to be rewritten. It will be updated automatically.

Easy to test: Apex is delivered with integrated tools for creating and evaluating unit tests. After an update, automatic tests are run to ensure the functionality of the code.

Versioned: The generated code can be saved for different versions of the API, so that the functionality is ensured even after updates and old versions can still be used after updates.

Development with Apex

The integrated Salesforce development environment can be used for development. It is, however, in great need of improvement. However, deficiencies can currently be compensated for using plugins. However, it is advisable to use more powerful development environments such as Cloud9 or Sublime Text, especially for more complex projects.
