Study Notes
Knowledge Age
- Peter Drucker introduced the concept of the 'knowledge age' in 1959.
- A key characteristic of knowledge is that it can be derived from old knowledge.
Databases
- Smartphones have GPS functionality that tracks your whereabouts.
- A database that supports data distributed across different sites is known as a distributed database.
- A desktop database is a database that is used by an individual on a single computer.
- A multiuser database that supports hundreds of users across many departments in an organization is an enterprise database.
- A database is classified as single-user or multiuser based on the number of users who can access it simultaneously.
- In a single-user database, only one user can access the database at a time.
- When a multiuser database supports fewer than 50 users, it is typically classified as a workgroup database.
Data Types
- Data best suited for deriving monthly totals and average sales is structured data.
- Semistructured data is commonly encountered and described as data that is not fully structured but has some level of organization.
- Unstructured data has not been processed to the same extent as highly structured data.
- Unstructured data typically found in corporations includes information such as emails, videos, and social media posts.
Data Management
- Data management is essential for proper decision-making and is a core activity for various entities.
- Data management involves the generation, storage, and retrieval of data.
- A discipline that focuses on data management is called data management.
- Efficient data management typically requires a database management system (DBMS) and a data dictionary.
Data Issues
- A problem that arises from the introduction of computerized file systems is data inconsistency.
- Data inconsistency can lead to incorrect decision-making processes.
- A data anomaly is an error or inconsistency in a database system.
- A data anomaly can be caused by inconsistent changes made to a database, also known as data corruption.
- Data integrity is important for a database to maintain accurate and reliable data.
Database Systems
- The DBMS is often referred to as the heart of a database system.
- The data dictionary is a component of a database system that stores relationships between data.
- The purpose of using relationships stored in the data dictionary is to ensure data integrity.
- The primary function of administrative utilities provided by a DBMS is to manage the database system.
- A DBMS accepts end-user requests through a user interface, such as a query language like SQL.
- A significant disadvantage of database systems is the cost of maintaining and updating them.
SQL and APIs
- Structured Query Language (SQL) is a special-purpose language used for managing relational databases.
- The purpose of providing application programming interfaces (APIs) to procedural languages in a DBMS is to allow for customization and integration with other systems.
