Data is the most powerful resource in any field or subject of study. In Biology, data comes from scientists and their actions, while any institution that makes sense of the data collected, will be in the forefront in their respective research field. In the beginning of any data collection endeavour, it is critical to find proper management techniques to store data and to maximise its utilisation. This presentation reflects upon the current trends and techniques of data modeling, architecture with a highlight on the uses of database, focusing on Bioinformatics examples and case studies. Finally, the future of bioinformatics databases is highlighted to give an overview of the modeling techniques to accommodate the biological data escalation in coming years.

2. In a nutshell….
Today almost every scientist realizes the need of storing their data sets using relevant
technology and models.
The architecture of a database system is greatly influenced by the underlying computer
system of the database system runs.
The access to relevant data, combining myriad data sources and coping with distinct
and heterogeneous systems is a tremendously difficult task.
Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of Science, University of Malaya
Advanced computing power, advanced informatics and the Internet has changed the way biological data are stored,
located and disseminated. In the past 20 years, scientists have engaged themselves in the
informatics discipline :
querying multiple remote or
local heterogeneous data
sources
integrating
manually
received data
manipulating it with
advanced data analysing
and visualizing tools.

4. Database
Fundamentals
Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of
Science, University of Malaya
In the simplest form, a database can be defined as
an organised and formal collection of information
stored in a computer readable format.
• Flat Files – Records without structured relationships
• Relational Databases- first introduction in 1970;
data in tabulated form
• Multidimensional (OLAP)- created using inputs from
a relational database where data is stored in a
cube or a multidimensional array.
• Graph and ontology based databases (NoSQL
databases)- Ontology based databases are in
principle made of the object oriented approach,
where the datasets are treated as objects, with
values and properties.
Common
approaches

9. Uses of
Databases
Knowledge
extraction
Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of
Science, University of Malaya
Databases are built to support front end applications which
ranges from simple query based systems to sophisticated
Artificial Intelligence enabled systems.
With the concept of big data that has taken Information
Technology - databases are extensively used for knowledge
extraction using algorithms that are run through large
volumes of data.
Thus, databases now have bigger role to play in many data
centric domains to function as platforms for machine
readable and machine interpretable format of information.
Protein Information and Knowledge Extractor (PIKE)
Lynx, a database and knowledge extraction engine for integrative
medicine.
Encyclopedia of Life (Parr et al., 2014).
10. • Databases are very useful for storing massive and ever growing
amount of data, which can be utilised for discovering patterns and
rules, automatically or even semi-automatically.
• This method is widely known as data mining and is conceived based
on logics in database systems (Paramasivam et al., 2014).
• A clean set of integrated data is usually stored in a data warehouse
before the data mining techniques applied. Key techniques
commonly used in data mining : classification, clustering,
prediction, association, text mining, link analysis and regression.
• Data mining is seen as an important concept in databases as the
process involves collecting data, creating database and
management, analyzing data and finally interpreting data (Han et
al., 2000).
Uses of Databases

11. Uses of
Databases
Visualisation
Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of
Science, University of Malaya
An effective visual design aids decision making
and interpretation to generate knowledge.
A data visualisation software or a script can be
used to find pattern, correlations or trends to
generate knowledge, which could not be seen in
textual or numerical content in a database.
One good example of data visualisation is using
graph based databases whereby the data is
retrieved in a visual context.
12. Focus of Presentation - Biological databases
Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of Science, University of Malaya
Database - a core
element of any
discipline that
produces large
amounts of data.
In Biology (particularly in
genomics), massive amounts of
data are being accumulated on
a daily basis via experimental
work, field work, software
analysis, illustrations,
microscopic photographs and
image acquisition.
This scenario has lead to
the construction of not only
single databases but also
the consortiums managing
large amounts of biological
data.

Big data domains - 2025
Stephens et al. (2015) compared other Big Data Domains such as, astronomy, youtube and twitter in their recent study on Genomics
perceiving to be Big Data science . They estimated that genomics is leading or at par with the other big domains in terms of terms of
data acquisition, storage, distribution, and analysis. Hence, the need to accommodate the data surge in biology is a challenge.

the Oxford Academic Journals.
Another important source of biological databases is the BMC Bioinformatics
(https://bmcbioinformatics.biomedcentral.com/).
31. Issues
Pertaining to
Biological
Databases
HETEROGENITY
Data is still in various forms, locations and in diverse formats
. One of the most intriguing phase in promoting the growth
of biological information centres is to correlate, synthesize,
disseminate, share and retrieve information in the form of
databases. Linking data is challenging.
DATA INTEGRATION
The fundamental problem affecting data integration is the
adoption of data standards. In Biology, data standards in
terms of vocabularies and ontologies have facilitated data
integration tremendously. However an undesirable situation
could arise if developers are from the computing
background and do not really understand the available data
standards in Biology, while, biologists are not very keen to
undertake technical tasks such as developing databases.
DATA SHARING
Publishing databases online is still not favored by scientists
especially if they are the data owners, as it may give rise to
copyright issues as well as misuse of the data by some
fraudulent parties. Scientists who may not want to share
unpublished data have their valuable data stored in personal
computers which are most of the time untapped. These kind
of speckled data, both textual and image date, will not allow
discovery of new knowledge and its evident that correlated
data can give rise to new discoveries in science.
DIGITIZATION
The development of databases require data to be in the
digital form and digitizing biological data is a daunting task.
It requires extensive manpower, enough equipments and all
of these requires funds. However, this can be overcome if
world class biological data centres makes databasing lenient
enough for underprivileged scientists.

Biological databases -
an integral part of
research in many
scientific areas (data
extraction, knowledge

biological simulations
to advanced analysis).

Important to relook at
models and
infrastructure
deployed in
construction of these
databases.

Older database models
such as relational, which
have been the core
technology behind
biological databases, are
losing its relevance with
regards to handling
exponential increase of
data.
4
In line with the
exponential increase
in size and
heterogeneity of
biological data, new
database models have
been proposed,
33. no SQL Database• Recent studies have explored the practical implementations of
NoSQL databases to help in developing a viable and usable
practice in information management.
• The growing data in genomics, metabolomics, proteomics and
metagenomics can be regarded as Big Data if these data sources
are harmonised.
• It is critical to explore back end data integration that are
streamlined into front end resilient computer systems for
performing seamless transactions, whether for simple search
algorithms or high level data science.
• In order to achieve this vision, these data sources need to be
mediated via ontologies and noSQL databases by adopting
parallel computing technology and Artificial Intelligence. In order
to facilitate the new paradigm, automated methods need to map
relational models (SQL based) into noSQL models which are the
essence of big data applications.
• NoSQL graph model has recently become very popular as it
presents a solution to many of today’s challenges such as
visualisation of data with complex connections and rich
relationships.Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of Science, University of Malaya
34. ARE NoSQL Databases
taking over traditional
relational databases?
Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of Science, University of Malaya
35. Advantages of noSQL over Relational
Data Science & Bioinformatics Laboratory, Institute of Biological Sciences, Faculty of Science, University of Malaya
Implementation and infrastructure costs are high. Most NoSQL database systems are open-source and can run on
inexpensive commodity hardware architectures.
Contrary to relational databases, NoSQL distributed databases offer higher performance that is capable of
spanning data across server nodes, racks, or even multiple data centers with no single point of failure.
NoSQL databases provide high availability due to its distributed nature and data replication.
Increasing heterogeneity of bioinformatics data such as free-text notes, images and other complex data that are unstructured or semi-
structured require new storage alternatives. Flexible data models or schemas powered by NoSQL databases allow complex data to be
stored easily.
Size of bioinformatics are escalating over time and eventually became a bottleneck for traditional relational systems.
NoSQL databases are based on horizontal scalability which permits effortless and automatic scaling.
