Home Economy 11 Key Advantages and Disadvantages of a Flat Organizational Structure 11 Key Advantages and Disadvantages of a Flat Organizational Structure Economy Jul 7, Flat organizational structure is an organizational model with few or in most cases no levels of middle management between the executives and the staff level employees. It was designed with the idea that knowledgeable and well-trained workers will be more productive when they are directly involved in the decision making process of the organization, rather than being supervised by many management layers.
This post is not about installing and configuring SQL Server or setting up a database on it. The very first query you will get when connecting to SQL Server data source includes an option for choosing the Data Connectivity mode.
Also, you need to put your server name; If your SQL Server instance is the default instance on your machine, you can use.
After selecting tables, click on Load. The data load dialog in this connection mode will be much faster because there is no process of loading data into the memory. This time, only metadata will be loaded into Power BI.
The data remains in SQL Server. The Data tab shows you the data in the Power BI model. However, with DirectQuery, there is no data stored in the model.
Also at the bottom right side of the Power BI Desktop, you will notice that there is a note about DirectQuery connection. You can check this process in SQL Profiler.
And running a SQL Profiler will show you that every time you refresh that report page or change something, there will be one query for every single visualization! One query, for each visualization. Even if two visualizations are showing the same thing, they still send two separate queries to the database.
Performance The understanding of how DirectQuery mode works, bring you straight to one point: How is the performance of this connection? The question about the performance is a very valid question to ask.
You must ask this question from yourself Before deciding to use this connection type of course. DirectQuery is performing much slower than the Import Data option. Import Data loads data into memory. It is always faster to query data from memory Import Datarather than querying it from disk DirectQuery.
However, to answer the question that how much faster it is, we need to know more details about the implementation. Depends on the size of data, specification of the server that the database is running on it, the network connection speed, and factors such as is there any database optimization applied on the data source, the answer might be entirely different.
The critical thing to understand is that this type of connection is the slowest type of connection, and whenever you decide to use it, you must immediately think about performance tuning for your database.
Using DirectQuery without performance tuning the source database, is a big mistake that you should avoid. Assume that we have a large table in a SQL Server database, a table with 48 million rows in it. And we are querying the only Sum of Sales column from that table.
Here is the performance I get when I have a normal index on my table with 48 Million records; A regular select sum from my table with 48 million records takes 4 minutes and 4 seconds to run.
That is a whole different topic on its own. And the most important thing is that; Performance tuning is different for each data source.
Your friend for this part would be Google, and the vast amount of free content available on the internet for you to study. Query Reduction One of the newest features added in Power BI is to help to reduce the number of queries sent to the database in the DirectQuery mode.
The default behavior of a slicer or filter in Power BI is that by selecting an item in slicer or filter, other visuals will be filtered immediately. In the DirectQuery mode, it means it will send multiple queries to the database with every selection in filter or slicer.
Sending multiple queries will reduce the performance of your report.
You may want to select multiple items, but with only selecting the first item, five queries will be sent to the database. Then with selecting the second item, another five queries will be sent to the database. The speed, as a result, will be twice slower. To fix this issue, you can set a property in Options of your Power BI file.
Then click on Query Reduction on the left-hand side the last item There are two sections in the query reduction. The first item is what I do not recommend in most of the cases.Disadvantages Forming a corporation requires more time and money than forming other business structures.
