Databases 2023, May
A relational database management system DBMS is essentially nothing more than a computerized system that allows you to store data. Users are provided with the means to perform several types of operations on the data in the database or to manipulate its structure. DBMS are classified according to the structures
Issues of structuring information are in great demand in the modern world due to the fact that the space is oversaturated with various information. That is why there is a need for the correct interpretation and structuring of a large amount of data. Without this, it is impossible to make important managerial and economic decisions based on any knowledge
Living in today's world, among other things, means actively using the Internet and its endless resources. Sites with movies, games, news, weather, latest technology, cosmetics, various social networks, forums, portals, chats - the list of what a modern person may be interested in online can be endless, but the main thing is not
Information has always had adequate dynamic interest. The development of programming, databases and technologies has radically changed the content and structure of interest. However, as often happens in the nature of things, everything calmly flows and improves, but at the right moment it changes dramatically
NoSQL is storage that doesn't conform to the relational database model and characteristics, they don't have schemas, they don't merge, and they don't guarantee the ACID property. The NO-system scales horizontally and uses a wide amount of main memory of the computer, solving the problem of large amounts of information
The information contained in spreadsheets and databases is not always necessary for the user at every moment of his work in full.

An integral part of most database tables is the "Counter" field. What is the peculiarity of this column, what functions it performs and what properties it has, we will consider below.

When working with databases, the user needs to receive information in a form that is convenient for display, summarizing the results for various parameters, using calculations and expressions. In the Access database, queries for data selection and reports are used for this. The article discusses another way to display and select the required values - a cross query
Cloud storage allows you to save large amounts of files on the Internet, access them from almost any device, anytime and anywhere (after authorization). In Google Drive, you can additionally work with documents, spreadsheets, forms, and presentations. The service quickly gained popularity among users, because it is reliable and convenient
Access databases, like other databases, store a lot of information in their tables. Some of them are interconnected, some are reference, some are entered by the user, and others are calculated automatically by the system. The variety of data in the database makes it necessary to classify them by type, depending on what information is stored in this field
The use of data is a problem in programming and developing information systems. Before analyzing a “large amount” of data and making a decision that guarantees a reliable and objective result, it is necessary to determine this “large amount”. The task becomes more difficult if the flow of information is growing rapidly, and the time to make a decision is limited
At present, a modern person cannot imagine his life without the Internet, but not everyone uses it to the fullest. In addition to searching for information, communicating in social networks, watching funny videos, information and other electronic materials can be stored free of charge on the World Wide Web. Now there is no need to buy photo albums and store them in a closet. Everything has long become automated and comfortable for humans
What is a data warehouse? As a rule, this is a database in which the entire mass of information on the activities of a particular company is stored.
