The ability to use real-time data has become the key to the success of any organization. Due to the revolution of Internet technology in the past, the amount of information that Received every second is a lot. Today, no matter what business or industry you are in, all business decisions are based on statistics. But here we must understand that the real power is not in the numbers themselves, the important thing is to turn those data into useful information.
Data Warehousing And Business Intelligence
The process of converting data into business understanding is called Business Intelligence. There are many different business solutions in the market such as SAP BI Suite, Microsoft SSIS/SSRS and Qlik along with QlikView and Qlik Sense. Many organizations struggle to choose the right solutions and – most importantly – integrate this in the right way. Let’s focus on Qlik, because it has a unique way of solving problems. Qlik relies on in-memory technology to create internal files that can act as virtual databases. Many developers who do not use Qlik technology have seen how Qlik works as a front-end solution, but most importantly not a backend. They tend to think of it as a “good looking” reporting tool, and position Qlik as the easiest BI software to remember.
Business Intelligence & Data Warehousing Simplified
One can do extensive analysis and advanced, powerful reporting with QlikView without creating a database. But if you want to have many QlikView applications created in many places in the organization and analysis and based activities, it will be a great benefit to think in the Data Warehouse.
· If your database has long tables that connect one table to another and dirty data?
If your answer is yes to just one of them, there is a 99 percent chance that you can improve the quality of your analysis and reporting by starting a data warehouse.
Key To Business Intelligence!. “the Greatest Value Of A Picture Is…
A data warehouse is an integrated database that stores data from multiple data sources and converts it into a comprehensive, quantitative data format for efficient querying and analysis. You can think of it as a “source of truth”. In simple terms, a data warehouse is a database used only for analysis and reporting that collects operational data, calculates and cleans it to create a unified copy used to display high data. level and detailed information.
In this step, the Qlikview application integrates different data and queries the necessary data and saves the extracted data in a QVD file. When stored in QVDs, Qlik takes advantage of disk compression and decompression. QVDs are files that deal with pointers and hash tables. They are very dense (10:1 ratio) and 10 to 100 times faster than traditional data access methods.
This step is very important and consists of a few steps. The former must be cleared in writing. Create new data fields that are used internally, join tables and create links between tables, to create data models. The data model in Business Intelligence is centralized, meaning that multiple tables are combined to create meaningful data for the end user.

In the final step we only need to read the converted QVD files so that someone can create QV applications for business users.
· It is not necessary to press save action every time when we restart the QV program after a small change in the program. For a long time, Business Intelligence and Data Warehousing were synonymous. You can’t do without another: to analyze a large amount of historical data, you have to organize, collect and summarize them in a special way in the database.
But BI’s reliance on this storage infrastructure has its downsides. Historically, data storage was or could be an expensive, limited resource. They take months and millions of dollars to establish, and even if they are, they only accept one type of analysis. If you want to ask new questions or process new types of data, you are facing a powerful development effort.
Data Warehouse Modernization
We will explain business intelligence and data warehousing in a modern way, and question the importance of data warehousing in BI.
Business Intelligence (BI) is the process of analyzing data and providing insights to help businesses make better decisions. In good BI practice, analysts and data scientists discover relevant hypotheses and can answer them using available data.
For example, if management asks “How can we improve the site’s conversion rate?” BI can determine why the conversion is low. The reason may be the lack of interaction with the content on the website. In a BI system, analysts can determine what engagement leads to conversion, and what’s at the root.

Tools and technologies that enable BI to take data – stored in files, databases, warehouses, or even large data stores – and run queries on that data, in SQL form. Using the answers to the questions, they create reports, dashboards and visualizations to help extract insights from the data. Insights are used by managers, middle managers, and employees in their daily operations for practical purposes.
A database is a relational database that collects structured information across organizations. It pulls data from multiple sources – the most common being online transaction processing (OLTP). Data warehouse collects, organizes and collects data for comparison and analysis.
The data warehouse maintains its integrity and integrity using a process called Extract, Transform, Load (ETL), which packages the data in chunks and places them in the desired database.

A data warehouse provides a long-term view of data over time, focusing on the collection of large amounts of data. The data warehouse component includes an online analysis engine (OLAP) to enable querying of many types of data.
Data warehouse software integrated with BI tools such as Tableau, Sisense, Chartio or View. They enable analysts to use BI tools to search for data in databases, make hypotheses, and respond to them. Analysts can also use BI tools, along with database information, to create real-time dashboards and reports and monitor key metrics.
Over the past few decades, many organizations have used decision aids to make data-driven decisions. These apps are polled and provide data directly from the data in the business database – no intermediary data warehouse. This is similar to the modern method of storing large amounts of unstructured data in a data lake and querying it directly.
Big Data And The Bi Ecosystem » Martin’s Insights
Colin White lists five problems that occur during the day of the license application, without a database:
These, and more, are the reasons why almost every industry has adopted a data warehouse system. All five of these problems still exist today. So we can do without a data warehouse, while still being able to do effective BI and reporting?
With the integration of data and technologies such as Hadoop, many organizations are moving away from complex ETL processes, where data is processed and stored in a data warehouse, to a simpler and more flexible approach called Extract, Load, Transform (ELT).
Data Warehouse Design And Development Approaches
Today ELT is widely used in data lakes, which store large amounts of unstructured data, and in technologies such as Hadoop. Data is dumped into the data lake without much preparation or structure. Analysts then identify relevant data, extract it from the data lake, transform it to fit their analysis, and explore it using BI tools.
ELT is a workflow that enables BI analysis while extracting data from data warehouses. But those same organizations that use Hadoop or similar tools in the ELT paradigm, also have data warehouses. They use it for critical business analysis of their business metrics – financials, CRM, ERP, etc.
Databases are still needed for the same five reasons mentioned above. Comprehensive data must be organized and transformed to be able to analyze business data with complex structures. If the manager wants to receive a weekly report, or an in-depth analysis of the income of all areas of the business, the information must be prepared and approved; Cannot be mined together from the data lake.

Can such analysis occur without a robust ETL process? Or in other words, are ELT strategies useful in information retention?
The new storage, data storage is a game changer, by allowing Download-Load-Transition (ELT) in enterprise data storage.
Make it possible to link and store large amounts of structured and unstructured data. With their data already in a trusted data warehouse, analysts can use queries to edit data online when needed, and work on editing tables in their BI tool of choice.

The main advantage is the short analysis time. With next-generation databases, you can go from raw data to analysis in minutes or hours, instead of weeks or months.
Databases have come a long way. The Monolithic Data Warehouse (EDW), which required a multi-million dollar project to set up, and only allowed very limited BI analysis for structured data types, will soon be a thing of the past.
