The document discusses the advantages of using a relational database management system (RDBMS) for bioinformatics data. RDBMSs provide concurrent multi-user access, security features, and easy web integration. They represent data using tables of rows and columns that enforce consistent data types. Common RDBMSs support the standardized SQL query language and have interfaces that allow integration into web applications. RDBMS transactions have ACID properties - atomicity, consistency, isolation, and durability - to maintain data integrity.

2. The rapidly growing amount of data
in bioinformatics makes the use of a
database management system
(DBMS) indispensable. Additionally,
modern DBMS provide advantages
like concurrent multiuser access,
security features, and easy web
integration.

3. The relational data model is based on the
single concept of relations for data
representation. Relations are perceived by the
user as tables whose rows are called tuples
representing the objects. All entries in a
column of a table are atomic values from the
same domain, and a single column is called an
attribute.

6. The use of relational DBMSs
has several advantages. Owing to its widespread
applicability, several commercial and even open-
source relational DBMSs are available. With SQL,
there exists a standardized and easy-to-learn query
language. Several standard interfaces available for
SQL allow the integration of databases into web
applications or other information systems.

7. ACID properties and RDBMS
Four crucial properties define relational database transactions:
atomicity, consistency, isolation, and durability—typically
referred to as ACID.
 Atomicity defines all the elements that make up a
complete database transaction.
 Consistency defines the rules for maintaining data
points in a correct state after a transaction.

8. Isolation keeps the effect of a transaction
invisible to others until it is committed, to
avoid confusion.
Durability ensures that data changes
become permanent once the transaction is
committed
