Aura

💬 In Plain Words: Salesforce has three generations of UI frameworks. Visualforce is the oldest (page-per-server-trip). Aura was the first component-based framework, but it is slow and heavy. Lightning Web Components (LWC) is the modern web standard and is vastly faster. The rule today is simple: All new custom development must be LWC. For declarative (no-code) development, use Lightning App Builder to assemble pages, and Dynamic Forms to put fields conditionally on a page without writing code. 📌 The Strategy Example: Imagine your org has a 2014 Visualforce quote PDF, complex Aura components built in 2018, and a brand new business requirement. The Verdict: Keep the Visualforce page (it's still the best engine for rendering PDFs). Leave the working Aura components alone, but freeze them (no new features). Build the new business requirement entirely in LWC. UI migration is a roadmap, not a reckless rewrite.

💬 In plain words: Salesforce Object Search Language (SOSL) lets you search for a specific word or phrase across multiple, completely unrelated objects (like Accounts, Contacts, and Opportunities) at the exact same time. When you combine SOSL with Lightning Web Components (LWC) or Aura, you can build powerful, Google-style global search bars that instantly return categorized results to your users without bogging down the system with dozens of separate SOQL queries. In enterprise Salesforce applications, users rarely want to search just one table at a time. They want to type a company name and instantly see the Account, the related Contacts, and any open Deals. While SOQL is great for fetching specific fields from a single object hierarchy, it is slow and inefficient for full-text searching across multiple objects. To build a true search engine widget, you must wire a SOSL query in Apex to your LWC or Aura frontend.
