What is the data package?
The data package is a collection of information stored in the finished database. The purpose of the data package is to "teach" the computer program to the package information and provide a one -off solution for instructing items such as software agents, programs that operate to provide links and other information to other programs. Data packages streamline the exchange of information between two sources on your computer, which excludes the need for end users manually enter long lists of information.
Think about the data package as an injection of knowledge for the computer. Normal uses for data packages include long lists of raw facts, such as a list of various major cities in the world around the world, or a list of employees and telephone numbers for organization. Compressing all this information into the data packages format allows the end user to quickly distribute information across a large number of computers without forceing every computer user to sit and write in the list literally.
This is largely a time -saving device for end users and computers, but the use of data packages also tends to increase simultaneous concerns in the network. Concurrent concerns relate to the need for everyone in the network to access the same data. In other words, for one network computer, it wouldn't have had a capital of the United Kingdom as London, while another computer has a Madrid. By installing information from data packages, the human typing error is largely minimized: all information installed on a computer or computers will be identical in all directions.
It is important that data packages are set correctly, as errors in the initial creation of data packages can undermine data integrity and turn what would otherwise have less errors for errors that can now go through the system. This emphasizes thpokud time to evaluate the information contained in the originalM data package needs strict control of facts. Without controlling reality, serious problems can easily occur during the width and network width.
Once the data package is installed, the host computer can then search the information and answer the questions. Since data packages are miniature databases, obtaining information is usually done through the structured query language (SQL). For example, when considering a data package containing countries and their main cities, SQL would "choose capital from countries where countries =" Russia "would immediately return" Moscow "to the end user. In this way, data packages can turn computer terminals into finished encyclopedies for searching for basic facts.
