What is VGA?
VGA is a video standard created for computer graphics. This standard allows images to be transmitted in real time from a computer to a monitor that has this output. VGA is the abbreviation for “Video Graphics Array”, works in analog mode, that is, it only serves to transmit images.
The VGA was introduced by IBM in 1987.
There are several cables in the market that convert the VGA standard to other standards, such as VGA to HDMI, VGA to SCART or VGA to S-Video.
A VGA camera is a camera that takes photos with 640×480 resolution, meaning there are currently cameras that take pictures with much higher resolution.
Commonly called “VGA”, the connector that connects the computer to the monitor is actually called “D-SUB connector” or “DB connector”.
It is a VGA extension called ” Super Video Graphics Array ” and works with other types of video cards, supporting even higher resolutions than its predecessor, the VGA.
What Is Data Warehouse:
Data warehouse is a digital data warehouse that is used to store detailed information about a company, creating and organizing reports through histories that are then used by the company to help make important decisions based on the facts presented.
The data warehouse serves to gather information from a company, so that it can better control a particular process, providing greater flexibility in the searches and the information they need.
In addition to maintaining a history of information, Data Warehouse creates standards by improving the analyzed data of all systems, correcting errors and restructuring data without affecting the operating system, presenting only one final, organized model for analysis.
Data Warehouse and Data Mart
A data mart is a subdivision or subset of a data warehouse. The data marts are like small slices of data warehouse, which store data subsets.
Usually the data mart is directed to a line of business or team, and your information usually belongs to a single department.
Data Warehouse Advantages and Disadvantages
Some of the key advantages of the data warehouse are:
- Inconsistencies are identified and resolved before data is loaded, which facilitates analysis and reporting;
- They contribute to the decision-making process through trend reports, exception reports and reports that reveal goals versus actual performance.
The data warehouse also has some disadvantages, among which:
- They are not an adequate solution for unstructured data;
- They can have high costs and can be outdated quickly.
Data Warehouse and Business Intelligence
Business intelligence is the process of collecting and processing information that supports the management of a business.
Usually, the various aspects of business intelligence use information gathered in a data warehouse. However, not all data warehouses are used in the context of business intelligence, because not all business intelligence applications require a data warehouse.
OLAP ( Online Analytical Processing ) is one of the most widely used tools for data warehouse exploration. OLAP makes it possible to change and analyze large amounts of data in several different perspectives.
The application of this tool can be used by managers of any area and level, providing information and assisting in the final decision. The use of OLAP can be applied in very different functions, and some of the most used ones vary from financial functions (analysis, cash flows, accounts, budgets, etc.) to marketing (price analysis, market volume, concluding in sales forecasts, profit, customers).
