Documenting SSIS Packages using Sequence Diagrams

Documenting SSIS Packages using Sequence Diagrams

November 25, 2020 by

In this article, I am going to explain in detail how to document SSIS packages using Sequence Diagrams and the importance of these diagrams in the field of software engineering, no matter which programming language are you using. In my previous article, I have talked about the various UML Diagrams that are being used to document various software engineering processes. Also, I have talked about modular ETL architecture and how to create such a modular package in SSIS. Sequence diagrams are also a part of the broader UML Diagrams which define the interaction between the various components in the system in a chronological manner.

Implementing a Modular ETL in SSIS

November 24, 2020 by

In this article, I am going to demonstrate about implementing the Modular ETL in SSIS practically. In my previous article on Designing a Modular ETL Architecture, I have explained in theory what a modular ETL solution is and how to design one. We have also understood the concepts behind a modular ETL solution and the benefits of it in the world of data warehousing. We have also related the concept of microservices architecture in software development to that of the modular ETL solution.

Designing a Modular ETL Architecture

November 17, 2020 by

In this article, I am going to demonstrate in detail the Modular ETL Architecture. ETL is a vast concept which explains the methodology of moving data across various sources to destinations while performing some sort of transformations within it. This is an advanced article that considers that the user has a substantial amount of understanding about how ETL is implemented using different tools like SSIS and the underlying working principle along with how to deploy multiple packages using SSIS. It is extremely important to implement a well-designed ETL architecture for your organization’s workload, otherwise, it might lead to performance degradations along with other challenges. To keep things simple, I will just explain the Modular ETL Architecture in this article which will be followed by a detailed hands-on tutorial in the next article – “Implementing Modular Architecture in ETL using SSIS”.

Explore the SQL query table hint READPAST

November 14, 2020 by

SQL Server creates an optimized execution plan based on the available inputs such as statistics, indexes. By default, it chooses a cost-optimized execution plan and executes the query. Sometimes, we use SQL queries table hints to override the default mechanism. Developers popularly use WITH (NOLOCK) query hint in a Select statement to avoid blocking issues.

Build a Google BigQuery Resource

November 12, 2020 by

Introduction

We can rely on Azure SQL to build reliable, high-quality relational database solutions. In the cloud, Google offers BigQuery as a big data product that has large data capacities, and a standard SQL syntax. Although it can handle data manipulation, it works better as a data warehouse product because of certain product limitations. If we can integrate these products, they become even more useful. This two-part article will show how to link these products together. Part one here will show how to build a BigQuery resource, and then build a Google OAuth refresh token, or security key. Part two will show how to set up an Azure SQL data resource, and build, configure, and test the Azure Data Factory that will link those resources.
