Defining databases: specifies the data types, structures, and constraints of the data to be stored. The database definition or descriptive information is also stored by the DBMS in the form of a database catalog or dictionary; it is called meta-data. 2. Constructing databases: is the process of storing the data on some storage medium, 3.

Study Notes
Implicit Meaning of Data
- Data carries underlying significance and interpretations that extend beyond its explicit representation.
- Contextual understanding is often required to uncover insights and patterns from raw data.
Database Management System (DBMS) Functionalities
- Facilitates the definition of databases, outlining data types, structures, and constraints for effective data storage.
- Stores database definitions and descriptive information as meta-data in a catalog or dictionary for easy access and management.
- Enables the construction of databases, which involves saving data on a specified storage medium.
Constructing Databases
- The process includes organizing, structuring, and saving data in appropriate file formats and storage systems.
- Ensures data integrity and accessibility for future use by implementing proper storage strategies.
Database Catalog or Dictionary
- Represents a repository containing meta-data that describes the database, including its structure, types, and constraints.
- Provides a foundational blueprint that guides data management and retrieval processes within the DBMS.
Representation Requirements
- A database must effectively represent all necessary data types and relationships to ensure comprehensive data management.
- A well-structured database facilitates efficient query processing and data manipulation.
Database Definition
- Involves the specification of the data types and structures to be stored, essential for managing data integrity and relationships.
- Meta-data serves as critical information for the DBMS, allowing it to optimize storage and retrieval operations.
