摘要

TLDRThe video serves as an introduction to SQL Server Integration Services (SSIS), explaining its role as an ETL (Extract, Transform, Load) tool. It highlights that SSIS is used extensively in the industry for data warehousing and migration projects. The presenter emphasizes that SSIS facilitates moving, copying, transforming, and loading data across different storage environments or servers. Commonly, organizations use it when they have a data warehouse setup. SSIS can handle database maintenance tasks as well, including things like rebuilding indexes and cleaning temporary tables. Besides SSIS, other ETL tools include Informatica and Teradata, but SSIS is specifically leveraged within the context of SQL Server environments. The course outlined in the video will cover the fundamentals of SSIS and how to implement data warehousing with it, focusing on control flow, data transformation, automation, and error handling. The instructor intends to provide real-world application scenarios as part of the learning experience.

    This video introduces SQL Server Integration Services (SSIS), a widely used ETL (Extract, Transform, Load) tool in the industry. SSIS is essential for data warehousing projects and data migration tasks, such as moving data between different databases or servers. It also supports database maintenance activities like rebuilding indexes and cleaning temporary tables. In the context of BI architecture, SSIS helps in copying data from various OLTP sources to data warehouses, establishing it as a core component in handling data preparation and processing tasks. The video outlines the course content, focusing on SSIS fundamentals and its application in data warehousing, including topics like control flow, data flows, transformations, and handling real-time scenarios with automation processes.

    welcome to analytics with nags
  • 00:00:26
    welcome to sql server integration  service introduction video and
  • 00:00:34
    this is about knowing what is ssis and  in what scenarios or what is the purpose
  • 00:00:43
    we need to use this particular tool let us explore  it in this video if you are new to this channel
  • 00:00:50
    hit the subscribe button and press  the bell icon for the notification
  • 00:00:57
    so it is sql server integration service or  ssis both are commonly used across the industry
  • 00:01:05
    and uh it is basically a etl tool so etl  stands for extract transform and load so we
  • 00:01:17
    have different data sources you need to extract it  and you need to do certain transformation before
  • 00:01:23
    loading it that is what the purpose of this  tool so when it will be used or most of the
  • 00:01:32
    organizations use this tool when they have a data  of arousing in place so if an organization having
  • 00:01:39
    data warehouse they need to have etl tool it  may not be a ssis it can be any other etl tool
  • 00:01:46
    like informatica or teradata there are a lot of uh  other etl tools available in the market but this
  • 00:01:56
    is one of the etl tool and it is used to implement  widely for data warehousing projects you also it's
  • 00:02:05
    used for data migration projects as well like  the existing applications the back end will be
  • 00:02:14
    oracle and the new edge applications they want to  build it whose database can be in the sql server
  • 00:02:23
    so they want to move this data from one database  to another or from different one server to
  • 00:02:28
    another servers as well so these kind of data  migration projects also people will use ssis
  • 00:02:36
    and finally last but not least like database  maintenance activities like sometimes we need
  • 00:02:44
    to rebuild the indexes and clean up some of the  temporary tables and also in the folder level you
  • 00:02:52
    need to do certain kind of cleaning process so  those kind of automation can also be achieved
  • 00:03:01
    using ssis so let us talk about uh the bi  architecture and we will try to understand
  • 00:03:11
    why this ssis plays the role right so this is  the sources different oltp sources and the data
  • 00:03:19
    preparation whatever you are seeing here the  second layer is called your data bursting layer
  • 00:03:25
    where you have a two different phases one  is staging and your data virus there will
  • 00:03:31
    be some other databases like dqs and mds most  of the companies using it some of them are not
  • 00:03:38
    using it depends that is fine but what  the role of ssis here as i said before
  • 00:03:44
    whenever you have a data virus in projects you use  some etl tools here it is ssis solves that purpose
  • 00:03:52
    like you need to take this data and store it here  that is moving your data it's not a moving it can
  • 00:03:59
    be a copying it should not say moving moving  means we will delete and load it here it's not
  • 00:04:04
    moving you want to uh copy the data from one place  to another place right then you will use this tool
  • 00:04:13
    right that is the main purpose so once you load it  here and you will build your fact and dimensions
  • 00:04:20
    in data arrows for that population also you will  use ssis and dqs to mds also you will need to move
  • 00:04:30
    here staging our either data virus it depends upon  the architecture so everywhere whenever there is a
  • 00:04:37
    data movement you will use it even here it will  be used like uh ssas processing task but it is
  • 00:04:45
    very small part of ssa is like five percentage  of it once you deploy it in ssas then you will do
  • 00:04:51
    regular processing those kind of stuffs you can  use it so as i said before it will be used for
  • 00:04:57
    data migration but the 80 percentage of the  organization used ssis for data warehousing
  • 00:05:04
    projects that is why i'm trying to explain the  ba architecture or data barrows architecture
  • 00:05:09
    with respect to ssis so what you can expect  in this course is like uh predominantly like
  • 00:05:18
    you will have ssis fundamentals like topics of  uh ssis fundamentals and then how to implement
  • 00:05:29
    the data variousing using ssis that is what i'm  going to cover in this entire ssis course right so
  • 00:05:40
    the fundamentals topics you can see control flow  data flows transformations control flow tasks then
  • 00:05:48
    i mean here you will have very high level overview  then we will jump deep into control flow task
  • 00:05:55
    precedence constraints what is containers looping  so this covers entire basics of ssis how you need
  • 00:06:03
    to work on a ssis project then there comes uh  implementation part like when you have a databar
  • 00:06:13
    rows you the ultimate aim is to build stat schema  dimension factor dimensions so how you use ssis
  • 00:06:20
    to populate this fact and dimensions and uh you  were fine with it right once you populated others
  • 00:06:28
    then in the event handlers like when something  is fail you need to automate some emails
  • 00:06:35
    those kind of real time scenarios i'm  going to cover then finally you have
  • 00:06:41
    these process are once you build it should be  stored somewhere so this is the place where
  • 00:06:46
    it can be stored and you can deploy it then you  will schedule an automation so this is what the
  • 00:06:53
    entire course is going to be let's try to explore  it in our upcoming videos if you like this video
