- Custom Attributes: Different attribute types (
integer,string,float,double) with operator overloading. - Record Management: Create, copy, and print records with ease.
- Relations: Handle multiple records, attribute types, and perform operations like union, difference, cartesian product, projection, selection, and renaming.
- Natural Join: Perform natural joins between relations.
- DNF Formula: Support for Disjunctive Normal Form (DNF) formulas for complex selections.
- Overloaded operators for comparison.
- Pure virtual function
copy_attrfor creating copies of attributes.
- Manages a collection of attributes.
- Supports copying and printing of records.
- Manages multiple records.
- Supports various operations like union, difference, cartesian product, projection, selection, and renaming.
- Contains utility functions for validating and performing operations on relations.
- Derived classes from
Attrfor handling specific types of attributes. - Implement comparison operators and
copy_attr.
- Structure for handling complex selection conditions in DNF.
-
Compile the project:
g++ -o rdbms rdb-*.cpp fort.cpp -
Run the executable:
./rdbms
-
Explore the functionality:
- Create relations
- Add records
- Perform operations like union, difference, cartesian product, projection, selection, renaming, and natural join.
