What is Inernet databases?
Internet databases are repositories of data that are stored and accessed through the internet. They allow users to store, manage, and retrieve structured information over the web, enabling a wide range of applications such as online shopping, social media, and cloud computing. Websites and applications can interact with internet databases to dynamically display and update information in real-time.
Give two reasons why data servers may be popular for object-oriented databases but not for relational databases?
Data servers are good if data transfer is small with respect to computation, which is often the case in applications of OODBs such as computer aided design. In contrast, in typical relational database applications such as transaction processing, a transaction performs little computation butmay touch several pages, which will result in a lot of data transfer with little benefit in a data server architecture. Another reason is that structures such as indices are heavily used in relational databases, and will become spots of contention in a data server architecture, requiring frequent data transfer. There are no such points of frequent contention in typical current-day OODB applications such as computer aided design.
Where are databases found?
Databases are found in a wide range of systems, such as computer applications, web platforms, cloud services, and enterprise servers. They are essential for storing, managing, and organizing structured data in various industries, including finance, healthcare, e-commerce, and more.

How is Access different from other Microsoft Office applications?
Each of the Microsoft Office applications are completely different to each other. Microsoft Access is for creating databases. Microsoft Excel can do some databases, but it is not designed to do them, as it is a spreadsheet application. Microsoft Access has many facilities to create databases. Those things are not present in the other applications, which are each designed for their own tasks. Microsoft Access allows you create tables, queries, forms and reports as the main elements of its functionality.

The relationships between users database applications DBMS and database?
The relationships between database applications DBMS and databases is as follows: Databases can be simple or complex. simple databases can be kept in a Microsoft Excel spreadsheet or they can be maintained in a user generated Microsoft Access database which can be programmed to query certain data that has been entered into that database over a period of time. Microsoft Excel and Microsoft Access are also applications that are used to build databases that can be incorporated into DBMS or Database Management Systems. These systems can be extremely complex or they can be simple meaning that maintenance to these systems is not demanding. If the DBMS is complex it may require an entire team of technicians and in some cases engineers.The relationship between users, database applications, databases, and Database Management Systems can be simplified even further - Users can access a database that has been created with a database application to query managed data that is a part of a uniform Database management system.
