Relational databases are based on the relational model, an intuitive, straightforward way of representing data in tables. In a relational database, each row in the table is a record with a unique ID called the key. The columns of the table hold attributes of the data, and each record usually has a value for each attribute, making it easy to establish the relationships among data points.

Cassandra has tables.

```
CREATE TABLE movies (
    movie_id UUID,
    title TEXT,
    release_year INT,
    PRIMARY KEY (( movie_id ))
);

```

Data being relational has nothing to do with support of ACID properties.

2. Why Cassandra is considered NoSQL database? despite it has tables
