What is data integration?
data integration is to merge multiple data sources into a single data source. This practice is often very time consuming and involved, because different data sources are probably incompatible. Things as simple as the different column names in the table are sufficient to require reformatting the date. This process is most common in situations where two groups started without connection, but are placed together after they worked independently. Data integration has become a more important topic due to the prevalence of free data sources and online databases.
The data integration data part can be almost anything if it is stored in the computer system. The actual data content is rarely as important as the way the data is stored. Most of the time the data is stored in databases, organized information systems. These systems contain unique items and fields that allow users to quickly find information.
The largest obstacle to any datintegration process is the data itself. In many casesCH, when the data was first set, there was no intention to merge the data file with another. This means that although two data sets can apply to the same thing, they are completely incompatible.
almost anything will be incompatible database. Something as simple as the difference in the presentation, such as the order of the field or the width of the column, may be enough to prevent easy merger. If the data is significantly different, for example one database that contains more or less information, the merger is much more difficult.
Two situations that require data integration more than any other are in the field and research areas. In the business world, the merger of department or companies requires combining previously separate information into a single structure. This form of integration is generally very difficult if the original groups used similar software and had similar information goals.
When an integra is carried out for the purposes of researchCE data, generally it is much more smoother. When one researcher allows you to access his information to another, both parties are generally engaged in the same process. This means that they will use similar methods to the catalog and store their data.
In the past, data integration has been a relatively small area of study data, but it has changed since the beginning of the 21st century. Since free online databases become more popular and accurate, companies are trying to get their information in sharing format. This allows them to release their information in public form and integrate private versions of well -known public interfaces into their systems.
