Breaking Through the Analytic Limitations of Access and SQL

Breaking Through the Analytic Limitations of Access and SQL.

Editorial Note

This article is in the Product Showcase section for our sponsors at CodeProject. These reviews are intended to provide you with information on products and services that we consider useful and of value to developers.

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.

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:

  1. 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.
  2. 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:
