Why Your Business Needs SQL


Thanks to the fast-evolving technologies, there has recently been an enormous increase of information. Did you know that more data has been created in the last two years than over the last few millennia combined? Every piece of information you see is stored somewhere, and often SQL Server helps with that.

What is SQL?

TSQL, short for Transact SQL is the main programming language used to retrieve, insert and update data held within a SQL database. The language is used by a front-end user interface system such as a web portal, allowing better organization and storage of information. TSQL is central to Microsoft’s SQL Server, which is our program of choice when working with databases.

When should SQL be used?

Managing your business’s data can become an annoyance if you don’t have the proper tools. While traditional spreadsheets can be used for managing small to medium sized data, they’re not equipped well enough to handle large amounts of data. If there’s too much data, the spreadsheet might even crash. This is where SQL steps in – it can handle data of any size, be it 100’s of records or billions of records.

As your business grows the more complex your data gets, and SQL is excellent for customizing queries for information retrieval. It can be used to search for specific pieces of information based on your criteria.

For example, Doctor Photo, one of our clients has several groups of customers in their system. They requested having a count of overall services an entire group uses within a month, because once a certain number is reached that group gets a discount. These are all constraints that we have effortlessly implemented in SQL with maximum efficiency.

Often, it is necessary to perform several updates to certain data. For example, to transfer money between two bank accounts, one account must be debited and the other credited. It needs to be ensured that neither update will fail as it would result in money loss for one of the involved parties.

To avoid these issues, databases use transactions. They are useful when performing multiple updates to the information in the database while retaining its integrity between individual updates. If a transaction is successful, all data modifications are saved to the database permanently. If it encounters any errors, all changes are rolled back and the database is not affected. Transactions also ensure all data is valid and committed without interference from other transactions that might be in place.

Integration with Power BI and Data Warehousing

In case your business deals with reporting services, we have some good news for you: SQL can easily be integrated into Power BI for data visualisation, interactive reports and drill through dashboards, and also plays a key role in data warehousing.

The term business intelligence refers to tools, technologies and applications whose purpose is to analyse and present business information, which helps optimize decision making and performance. Power BI is one of those tools and, along with features mentioned above, allows extracting insights and sharing them within your organization.

Although data warehouses may appear similar to databases, there are a few key differences between them. Databases are optimized to enable fast access to current data in any ongoing business processes, using a single source. Data warehousing, on the other hand, uses multiple data sources, its main purpose being reporting and analytics.

More and more businesses are becoming digitized, which means the emphasis is on database management. If the information load gets complex, it’s easier to make errors when trying to manage data manually. SQL keeps things simple and organized, protects your database and ensures faster performance of your business processes. It’s quick and efficient, and if you decide it’s worth it, we at Dolphin Networks can help you achieve your goals.
