RDBMS:
RDBMS stands for Relational Database Management System. It is a database management system based on the relational model i.e. the data and relationships are represented by a collection of inter-related tables. It is a DBMS that enables the user to create, update, administer and interact with a relational database. RDBMS is the basis for SQL, and for all modern database systems like MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access.

OODBMS:
OODBMS stands for Object-Oriented Database Management System. It is a DBMS where data is represented in the form of objects, as used in object-oriented programming. OODB implements object-oriented concepts such as classes of objects, object identity, polymorphism, encapsulation, and inheritance. An object-oriented database stores complex data as compared to relational database. Some examples of OODBMS are Versant Object Database, Objectivity/DB, ObjectStore, Caché and ZODB.

Sir, on draw.io there are many types of tables available. Is there a particular notation we should use?

Are we to submit only the logical diagram or the logical schema as well? I missed that part in the beginning of the lecture.

Sir for the CW do we have to put our UoW ids in the front of the entity name and attribute names?

The data type of a column defines what value the column can hold: integer, character, money, date and time, binary, and so on.

SQL Data Types

Each column in a database table is required to have a name and a data type.

An SQL developer must decide what type of data that will be stored inside each column when creating a table. The data type is a guideline for SQL to understand what type of data is expected inside of each column, and it also identifies how SQL will interact with the stored data.

Note: Data types might have different names in different database. And even if the name is the same, the size and other details may be different! Always check the documentation!

MySQL Data Types (Version 8.0)

In MySQL there are three main data types: string, numeric, and date and time.

String Data Types

Numeric Data Types

Note: All the numeric data types may have an extra option: UNSIGNED or ZEROFILL. If you add the UNSIGNED option, MySQL disallows negative values for the column. If you add the ZEROFILL option, MySQL automatically also adds the UNSIGNED attribute to the column.

Date and Time Data Types

DATE

A date. Format: YYYY-MM-DD. The supported range is from '1000-01-01' to '9999-12-31'

DATETIME( fsp)

A date and time combination. Format: YYYY-MM-DD hh:mm:ss. The supported range is from '1000-01-01 00:00:00' to '9999-12-31 23:59:59'. Adding DEFAULT and ON UPDATE in the column definition to get automatic initialization and updating to the current date and time

TIMESTAMP( fsp)

A timestamp. TIMESTAMP values are stored as the number of seconds since the Unix epoch ('1970-01-01 00:00:00' UTC). Format: YYYY-MM-DD hh:mm:ss. The supported range is from '1970-01-01 00:00:01' UTC to '2038-01-09 03:14:07' UTC. Automatic initialization and updating to the current date and time can be specified using DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP in the column definition

A time. Format: hh:mm:ss. The supported range is from '-838:59:59' to '838:59:59'

YEAR

A year in four-digit format. Values allowed in four-digit format: 1901 to 2155, and 0000.
MySQL 8.0 does not support year in two-digit format.

SQL Server Data Types

String Data Types

Numeric Data Types

decimal(p,s)

Fixed precision and scale numbers.

5-17 bytes

numeric(p,s)

Fixed precision and scale numbers.

5-17 bytes

float(n)

Floating precision number data from -1.79E + 308 to 1.79E + 308.

4 or 8 bytes

Date and Time Data Types

Other Data Types

sql_variant

Stores up to 8,000 bytes of data of various data types, except text, ntext, and timestamp

uniqueidentifier

Stores a globally unique identifier (GUID)

xml

Stores XML formatted data. Maximum 2GB

cursor

Stores a reference to a cursor used for database operations

table

Stores a result-set for later processing

MS Access Data Types
