Databases
The database consists of characters or a group of characters that form a field. A related group of fields creates a record. The records are combined to form a file. The files are grouped to form a database. Databases can contain only characters or can also include images, sound, and movies to form a multimedia database. Businesses need data so that it is available, modifiable, and controllable. Data files can be organized in a sequentially, direct, or indexed file. The data must be kept up to date and correct. To do this a data validation process must be used. The advantage of data files is that they are easy to use. The disadvantages are that when multip
This is the primary advantage of the database method of managing data. We also read a little on: database use in information systems such as personal databases and shared databases, data warehouses who share data through the use of data marts, data mining, multidimensional databases which is basically converting the data into graphs or charts, analysis of the data using on-line analytical processing (OLAP), and finally the database manager who manages the database. There are also object-oriented and object-relational databases. The most common type of database in use today is the relational database utilizing one of the relationships. The final disadvantage is that systems utilizing this system can be complex to develop. These databases store the data and instructions in the database. The database consolidates the different data files into one database and is managed with database management software. le data files are required for the business a lot of duplication of data and effort is involved; this is where databases comes to play. The database is a collection of data and relationships in the stored data. Another disadvantage is that the database is stored altogether on one disk, if that disk is damaged or destroyed all data is lost. The database will then update the other databases within the whole database based on that input. Database relationships can be one-to-one, one-to-many or many-to-many. With the use of database software queries can be used to access data in the form and with the elements desired in a rapid amount of time. Through the relationships established in the database the updating of the database normally requires single entries for one field or record.
