If data is changed in a database, it can lead to inaccurate information, potentially causing incorrect decision-making. It may also impact system performance if the changes are not properly managed, leading to data inconsistencies or loss. Regular backups and proper access controls can help mitigate these risks.

What is a document that describes database objects and their data types?
A data dictionary is a document that describes database objects such as tables, columns, and their corresponding data types. It provides information about the structure, relationships, and constraints of the database schema.
What diff between the database and database system?
In simple terms, you can look at the database as being the files or tables with the data. A database system includes the other elements like queries, reports, forms, programs and other elements that manipulate and support the data in the database.
What is the name of the system database that contains descriptions of the data in the database?
The system database that contains descriptions of the data in the database is called the data dictionary or metadata repository. It stores information about the structure, definition, and organization of data elements within the database to help users and systems work with the data effectively.
Data base state vs database schema?
The database schema is the description of the database. It defines how the database is set up and what data it is to contain and control. This description is given to the DBMS to manage the data. The database state is an image of how the database looks at any given time. The database schema is set unless you change how the database is structured. The database state will change whenever new data is entered into the database and the database is updated.
What is the difference between database and data warehouse?
Typically, a database versus a data warehouse, is "OLTP" (online transaction processing). That means that live inserts/updates/deletes happen to the database all the time. A data warehouse is used for statistics and trending. Nighly data feeds from stores are populated into the tables. During the day, no inserts/updates/deletes occur on the database--it is used for data gathering (queries) only.
How would copy and paste data in a way that the data automatically updates when the original information changes?
If you are copying formulas, then updates will occur when the actual data is changed. Raw data must be changed by hand. Data can also be linked between applications, so if the data is coming from another program, like a database or a word processor , if a paste link has been done, then the changes will happen in the linked file.If you are copying formulas, then updates will occur when the actual data is changed.

Why would you copy a table from access and paste it as a link in Excel?
It is possible to share data between different applications. It is often better to do some kinds of processing work in one application than another. So if you had data in a database that you wanted to do a lot of calculations on, and also keep up to date with what is in the database, then you could put a link into the spreadsheet. The spreadsheet can then do its calculations and if anything changes in the database, then those changed will be recognised in the spreadsheet. That way you would not have to keep copying data across to Excel from Access.It is possible to share data between different applications.

Is data duplication is a desirable aspect of a database?
No it is not. A well designed database will have no duplication. Duplication of data takes up more space. It can also lead to inconsistencies in the data. If the same data is there more than once, it can sometimes that not all copies of it are changed when they have to be. So for example, you could have a person listed twice in a database. If they got a new phone number and this was only changed in one of the entries for them on the database, you would now have the same person listed twice, but with each having a different phone number. If they are on the system once only, then there cannot be those kinds of inconsistencies.No it is not. A well designed database will have no duplication. Duplication of data takes up more space.
