Fundamentals of Datawarehouse

A data warehouse is a data repository which is used to store large quantities of historical data that are mostly used for creating reports that help businesses to identify their weaknesses and strengths. For example, demographics data about people of a region can help businesses identify the needs and preferences of the region’s population. A data warehouse acts as a central storage for storing data that comes from one or more heterogenous sources. It also consists of data which can be old and of historical value. One of the most important applications of this type of system is that it is used for supporting business intelligence and data analytics applications.

Question

### Creating an Entity in SQL

**Task:**
Write an SQL statement to create the entity shown. Use appropriate data types for the data that must be stored in each attribute.

**Entity Diagram:**
The diagram displays a table named `MEMBERSHIP`. The primary key (PK) of the table is `MEM_NUM`. The attributes of the table are as follows:
- `MEM_FNAME`
- `MEM_LNAME`
- `MEM_STREET`
- `MEM_CITY`
- `MEM_STATE`
- `MEM_ZIP`
- `MEM_BALANCE`

**SQL Statement:**
Here is an example of how you could create this entity using an SQL `CREATE TABLE` statement with appropriate data types:

```sql
CREATE TABLE MEMBERSHIP (
MEM_NUM INT PRIMARY KEY,
MEM_FNAME VARCHAR(50),
MEM_LNAME VARCHAR(50),
MEM_STREET VARCHAR(100),
MEM_CITY VARCHAR(50),
MEM_STATE CHAR(2),
MEM_ZIP VARCHAR(10),
MEM_BALANCE DECIMAL(10, 2)
);
```

**Explanation of Data Types:**
- `MEM_NUM`: Integer type (`INT`) used as the unique identifier for each record.
- `MEM_FNAME` and `MEM_LNAME`: String type (`VARCHAR`) with a length of 50 characters for storing first and last names.
- `MEM_STREET`: String type (`VARCHAR`) with a length of 100 characters for storing the street address.
- `MEM_CITY`: String type (`VARCHAR`) with a length of 50 characters to store the city name.
- `MEM_STATE`: String type (`CHAR`) with a fixed length of 2 characters for storing the state abbreviation.
- `MEM_ZIP`: String type (`VARCHAR`) with a length of 10 characters to accommodate different ZIP code formats.
- `MEM_BALANCE`: Decimal type (`DECIMAL`) with up to 10 digits total and 2 digits after the decimal point, used to store balance amounts.

This SQL statement creates a `MEMBERSHIP` table with columns tailored to storing membership information, ensuring that each column has the appropriate data type for the kind of data it will hold.

Assumptions: You can make the following assumptions in this project. The database stores information about houses, each with a house ID, address, and zip code. The database stores information about person, including person ID, house ID where the person lives, person name, phone number, and status where 1 means currently tested positive (i.e., the most recent test result is positive), 0 means currently tested negative (i.e., the most recent test result is negative), and null (no test so far so status is unknown). The database stores information about a person's all past tests, including person ID, test date, and result (1 means positive and 0 negative). The database stores information about events (could be gathering, party, etc.). Each event has an event ID, event name, date, and address.
