Finding the Right SQL Developer with a Good Job Description


Structured query language (SQL) is the foundation for back-end database programming and design. It’s the language that allows us to access and manipulate databases, execute queries, retrieve data, edit data, and insert new data—essentially, everything that makes databases interactive, not static. If you want your website or application to be dynamic and interactive, you’ll need a SQL developer to design and program your database.


Using the SQL coding language, a SQL programmer designs tables, writes queries, and ensures that these queries perform at optimal speeds. Most SQL developers are either database administrators or experts in managing database development. There are different flavors of SQL depending on the platform you use, but they all perform the same basic functions—retrieve, add, edit, and delete database data. And a SQL programmer will be well-versed in all of these functions. Continue reading this article at UpWork

This blog post helps explain SOQL, or the Salesforce Object Query Language, to developers familiar with SQL. SQL is the granddaddy of query languages, and it’s no surprise why.

Almost every developer has a working knowledge of SQL and the basics of communication with an RDBMS. This makes it easy to adopt SOQL. After you read this post, you’ll understand a few basic tenets of how SOQL works and why Salesforce even bothered to create its own SQL-like language.

Trust, multitenancy, SOQL, and the query optimizer

Multitenant architecture is fundamental to the Salesforce platform. Without an understanding of this, you will puzzle at certain behaviors and features. The multitenant architecture white paper is a must read. There’s also a Trailhead unit on our architecture that’s worth a few minutes of your time.

At the database layer, multitenancy means that there is a single set of tables shared by many different customers. This is the “real” data model in our data centers. It’s complex and consequently requires highly complex joins to get the right data to the right customer and user for any given request. Consequently, we abstract the “real” data model and materialize this into a customer-facing and customer-specific data model in the form of SObjects (Salesforce Objects).
