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.
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.
A database is a collection of organized data, while a database system is a software application that manages, stores, and retrieves data from that database. The database system includes software for managing the database, as well as tools for interacting with the data, ensuring data integrity, and controlling access to the data.
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.
A database is a structured collection of data that is organized in a way that facilitates efficient storage, retrieval, and updating of data. A data warehouse, on the other hand, is a specialized type of database that is specifically designed for data analysis and reporting. Data warehouses typically store large volumes of historical data from various sources to support business intelligence and decision-making processes.
The database state refers to the current data stored in the database, including all records and their values. On the other hand, the database schema refers to the structure of the database, including tables, columns, constraints, and relationships. The schema defines how the data is organized and stored in the database.
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.

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.

threats to data security may be _____ threats to the 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.

i will not tell you :P
A business could go in for a database if it has a lot of data and there are concerns about redundancies
DBA stands for database administrator in short. The DBA is person that is responsible for maintaining the data. A DBA has to ensure if the data is changed then it does not cause any inconsistency and integrity loss.The are different types of DBA's (Database Administrator)A Database administrator is responsible the all maintenance on the database servers he is charged with.DBA's are often times Database Developers as well.
A database is a collection of data. Data represents items that are stored within the database.
How do you validate and retrieve data from database?" How do you validate and retrieve data from database?"
The mean is changed.
