Overview
Although they
are often a cornerstone of a company’s analytic toolkit, traditional databases,
such as Access, and query tools, such as SQL, are designed for storage and
simple queries, not for creating the complex analytics that are required by
today’s fast-moving businesses. New technologies can help organizations get
over the analytic limitations of Access and SQL, especially when dealing with
the demands to process more data, change analytics more frequently, and make
analytics available to more decision makers – all at greater speed than ever
before. To experience the benefits of an agile, visual analytic environment

Business Demands Are Driving the Need
for More Specialized Analytic Tools
Many organizations use using standard relational databases, such as
Access, and script-based query tools, such as SQL, for analytics. Because of
their wide availability, these products have represented for years the core set
of technologies on which business groups have managed their business. But
these tools were designed for data storage and for simple queries that are
often inadequate to tackle the analytic challenges that most businesses face
today. Today most organizations are relying more heavily on analytics to compete
and the analytics they need to perform to improve business performance are
forcing them to deal with:
- More data – Difference-making
business improvements require analysis of more data and more disparate data
sources, especially sources that that come from different business departments
and even from other businesses, such as partners, suppliers, and third party
information providers.
- More speed – Business
reaction time must be faster than traditional IT-led business intelligence initiatives
which can delay changes because of limited IT resources.
- More change – A
dynamic business world brings new data sources, relationships, competitors
& risks.
- More decision makers – More decisions mean more business questions, forcing IT to turn
from data owner to facilitator
Limitations of Relational Databases and
Query Languages
Access and SQL fall down in the face of the today’s analytic
challenges because they were designed around a relational database structure
that does not lend itself to today’s fast moving, ad hoc analytic environment.
Relational databases, such as Access, were designed for storage, reporting, and
simple queries and have the following limitations when it comes to analytics:
-
Table structure limits flexibility – instead of thinking directly about the analytic problem at hand,
analysts using relational databases are forced to view the problem in terms of
tables and to work with a complex collection of tables. But tables impose a
structure that is fairly rigid and blocks visibility to the data and imposes a
high overhead even for "small" changes. In some cases, if you want to add a
new data source to your analysis, you may need to tear down the original
structure and rebuild it to take into account the new requirements. Tables
also have size limits (2 GB for Access) that create a ceiling in terms of the
amount of data an analyst can consider. If you come close to the ceiling,
performance will degrade quickly and you will have to divide data up in less
logical chunks and restructure your queries based on the different data
divisions to perform your analysis.
-
Query interfaces are either too simplistic or
too complicated – Databases, such as Access, offer
wizard-based query tools (Access offers Expression Builder) , which limit the
analysis of complex expressions, or script-based query languages, such as SQL,
which increase the overhead associated with queries and limit the query
capability to very technical analysts and programmers. SQL is also difficult to
debug compared to more visual representations of analytic logic. There is no
middle ground that serves the need for more managers and analysts to have
free-form exploration or discovery capability – a critical analytic technique
for ad hoc analytics and for projects where you are trying to identify root
cause analysis and investigations require a long sequence of queries.
- Data modelling creates chick and egg problem – One of the major characteristics of analytic projects undertaken
with relational databases is the need to create a data model reflecting the
relationship between all the different tables. This is a time consuming and
difficult task and like the table structures themselves, it is essentially
creating a rigid structure not suited to changing business requirements. When
it comes to the success of an analytic project, this is often the hurdle that
causes most people to stumble because building the data model presumes that you
know all the questions that will be asked of the data set, but you usually
don’t know which questions you will want to ask until you have built the data
model on which the analytic application is built.
New Technologies Are Designed for
Analytics, Agility
Today there are alternatives
to relational databases that are designed from the ground up to address the
analytic needs for more data, more speed, more change, and more decision
makers. While several technology approaches exist, they all share these
characteristics:
- A flexible data model – No over-arching data model, or schema, is required so you can build
your analytic incrementally and immediately without waiting to gather all
possible requirements. This eliminates the overhead costs and effort
associated with the rigid structure of a traditional relational database and makes
it easier and more practical to unify highly diverse data sources or change an existing
analysis.
- Speed appropriate for rapid prototyping – The more flexible data model allows you to mash up data and build
analytics very quickly compared with traditional database and business
intelligence tools. This makes it more practical for you to consider new data
sources, explore data more completely, evaluate new hypotheses, and make ad-hoc
discoveries.
- Easy to use query interfaces – Query interfaces can be visual in nature or search-based allowing
not just programmers, but business analysts to investigate hypothesis and make
discoveries. Visual models have the added benefits that they can make processes
more consistent by visually documenting the step-by-step process, they can be
used to automate analytic processes, and they allow rapid, pinpoint changes.
The Lavastorm Analytics Engine – An Agile
Analytic Environment
The
Lavastorm Analytics Engine is a new breed of analytic technology that provides
an agile way to analyze, optimize, and control both your data and your
processes. Over the past 15 years, the product has generated billions of
dollars in business value in demanding analytic environments where
organizations needed to handle extremely high data volume, integrate very
dissimilar data, and respond in near-real time.
The
Lavastorm Analytics Engine’s visual, discovery-based environment allows
organizations to bring together diverse data with tremendous ease, helping them
reduce analytic development time by 90% or more, and use the analytics to
transform their business. The engine combines two unique capabilities that
allow you to capture the potential value from the data:
-
Data
discovery
– You can combine large volumes of diverse data and explore it freely using a
visual analytic development environment. Data discovery allows you to identify
new insights or to use the enriched data to make better-informed decisions.
- Continuous
analytics
– You can continuously run the visual analytic models that you create with the
engine, allowing you to automate various analytic processes, such as data
cleansing and data quality processes, and business processes.
Along with
these capabilities, the Lavastorm Analytics Engine is offers advantages over
Access and SQL for analytics when you have the following business requirements:
