What is SQL?

SQL, which stands for Structured Query Language, is a standardized language specifically designed to interact with relational databases. It serves as a database language, enabling the management of transactions on data. Recognized as an American National Standards Institute (ANSI) standard, SQL facilitates the processing and backend storage of data, which is essential for websites and various applications such as Facebook, WhatsApp, and Instagram.

SQL is used to perform a variety of functions on databases, including creating, accessing, and manipulating data. It allows for the creation of new databases, tables, and views, as well as inserting, updating, and deleting records in a database. SQL is also used to retrieve data, and it does this quickly and efficiently, making it a go-to language for data processing. Due to its interactive and functional nature, SQL has become the most commonly used database language, supporting the needs of nearly any company that stores relational data.

Furthermore, SQL's design as a Client/Server language helps connect the front-end with the back-end of applications, ensuring seamless data management and protection from unauthorized access. Its integration capabilities with other scripting languages like Python and R extend its use to areas such as machine learning. Notably, SQL does not require extensive coding skills to use, making it accessible for a wide range of users and applications.

SQL Plugins for Excel

Master Data Services Add-in for Excel

The Master Data Services Add-in for Excel is a robust tool that facilitates the interaction between Microsoft Excel and Master Data Services (MDS). It streamlines the process of loading, modifying, and publishing data directly from Excel by allowing users to load filtered lists of data from MDS into their spreadsheets. This add-in is compatible with Windows operating systems and supports SQL Server versions 2016 SP2, SQL Server 2017, SQL Server 2019, and SQL Server 2022.

Data Manipulation and Publishing

Once data is imported into Excel using the Master Data Services Add-in, users can leverage Excel’s familiar interface to work with the data. This includes creating entities, attributes, and utilizing Data Quality Services (DQS) for matching data before loading it back into MDS. After making necessary changes or analysis, the data can be published back to MDS, ensuring that the central data repository is up-to-date with the latest changes.

Pre-requisites and Limitations

To use the Master Data Services Add-in for Excel, certain prerequisites must be met. ActiveX controls must be enabled, and Office Automation Security settings need to be configured to either Level 1 or Level 2, which correspond to enabling macros or using the application's macro security level, respectively. Furthermore, there is a payload size limitation of 5 MB for requests and responses, and the add-in restricts the size of a range to five million cells for get operations.
