When it comes to Salesforce customisations, there are two main types, declarative and programmatic.
Declarative customisations are point and click. These allow non-developers to build powerful customisations by using a wizard to create custom fields, automation and tables of data. One of the latest developments Salesforce has brought out is Mulesoft Composer, which allows integrations into other systems to take place using only clicks!
Programmatic customisations on the other hand are built with code. Whilst you can do almost anything with declarative customisation, there is a limit to more complex solutions. Apex is Salesforce’s coding language and may be required if the requirement is particularly complex.
Lightning development, on the other hand, is Salesforce’s UI coding language, this can be used to create completely custom screen layouts. In addition, it’s common that in most integrations, some level of coding experience using API’s will be needed.
