Data Access Modes in SSIS OLE DB Destination: SQL Command vs. Table or View

October 5, 2021 by

This article compares the SSIS OLE DB Destination SQL command with the “Table or View” data access mode. In a previously published article, SSIS OLE DB Destination vs SQL Server Destination, in this series, we explained the OLE DB Destination component in SSIS and illustrated how it differs from the SQL Server Destination component. So, in this article, we will focus on the OLE DB Destination data access modes, not the component itself.

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”.

An introduction to SSIS Data Lineage concepts

September 3, 2020 by

In this article, I am going to discuss SSIS data lineage concepts, which are often used while designing ETL workloads on a data warehouse. Although this article is focused on implementing data lineage using SSIS, it does not only confine to SSIS but to any ETL tools in the market using which data is moved from one source to a destination. In my previous article, Understanding Data Lineage in ETL, I have already discussed the generic importance of data lineage concepts for any ETL tool. I would definitely suggest you have a look at it if you want to understand in general how data lineage helps to track the source of a single record in the warehouse.

Understanding Data Lineage in ETL

September 3, 2020 by

In this article, I am going to explain what Data Lineage in ETL is and how to implement the same. In this modern world, where companies are dealing with a humongous amount of data every day, there also lies a challenge to efficiently manage and monitor this data. There are systems that generate data every second and are being processed to a final reporting or monitoring tool for analysis. In order to process this data, we use a variety of ETL tools, which in turn makes the data transformation possible in a managed way.

Getting started with SSISDB

July 13, 2020 by

In this article, I am going to explain how to start using the SSISDB database, also known as the SSIS Catalog database. In my previous article, I have provided an overview of this SSIS catalog database in detail. I would recommend you read that article, before moving on further with this if you want to understand how the SSIS catalog database works. The SSIS catalog database is one single database in which you can deploy all your SSIS packages and then organize and manage those packages centrally.

Introduction to the SSIS Catalog database (SSISDB)

July 7, 2020 by

In this article, I am going to explain in detail the SSIS catalog that can be used to deploy SQL Server Integration Services (SSIS) projects. Using this catalog, developers and database administrators can easily deploy and manage their integration services projects after deployment. The SSIS Catalog database was introduced in SQL Server 2012 and prior to that users had the following three options to deploy their SSIS packages:

Understanding SSIS memory usage

July 3, 2020 by

In this article, I am going to explain in detail SSIS memory usage and how can we optimize our tasks and the data flow to leverage maximum benefits from the in-memory operating tool. As you might be aware, SSIS also known as SQL Server Integration Services is a data integration tool, provided by Microsoft which comes shipped with the SQL Server editions. SSIS is an enterprise-scale, in-memory data integration tool which can be used to move data between different databases or different servers in a comfortable yet manageable way.

Using the SSIS Script Component as a Data Source

June 25, 2020 by

Introduction

SSIS Script component is one data transformation tasks in SQL Server Integration Services (SSIS). SSIS is an integration tool in the Microsoft BI family to extract data from heterogeneous data sources and transform it to your need. Apart from the standard data sources such as databases, text files, excel files, and web services, there can be instances where you need to retrieve non-traditional data sources. For example, let us say you want to extract the details of text files such as file sizes, created date, etc. In these types of scenarios, traditional data sources cannot be used.
