Data Warehousing

Whether you are building a large data warehouse for your enterprise or a series of small data marts for your business, we can design the right database for you. It is a common misconception that to have successful data warehouse you need lots of expensive tools. While some tools can indeed provide value, they do not always provide clear ROI. A more valuable data warehouse can often be developed with nothing more than a good design and simple tools like Microsoft Access. Epsolon has the experience to meet with you and help you move towards a data warehouse solution that will provide optimal value within your budget.
Already have a data mart or data warehouse? Trying to figure out why it's running slow or why you cannot get the right answer out of it? One of our consultants can review what you currently have in place and make suggestions for how to make it better. Top consulting firms routinely take their designs and conduct peer reviews to come up with the best solution. One of our consultants can fill this role for your company. Our philosophy is to take a collaborative approach to understand what you have done so far and make suggestions for improvements in the future. We will not criticize what has been done so far, but we will often challenge the status quo and challenge you to take the steps necessary to put an improved design in place for the benefit of your business and your data warehouse users.
If you already have a data warehouse, chances are you have some type of Extraction, Transformation and Loading (ETL) process to move data from your source systems into your warehouse. There are many tools on the market that do this, and we have experience with most. Whether you are building Informatica mappings, Ascential jobs, or PL/SQL packages we can help you design and build an efficient structure for you ETL and help you put in place a quality delivery mechanism for you data warehouse.
Epsolon is experienced in creation and configuration of metadata management tools. A single repository of business and technical definitions is critical for design, development, and implementation of any data warehouse. Metadata management is the first step in defining a single version of the truth, and the framework for building and scaling the data warehouse.
Is your organization ready for a business intelligence or data warehouse project? Or if this initiative is underway, does your project have the ability to succeed? These projects are large and expensive and require a certain degree of readiness and commitment to ensure their success. Epsolon can evaluate your organization to determine these requirements. Epsolon helps our client become successful from any point in the project life cycle by determining factors of risk within your organization.

Epsolon provides assessments and reviews for ETL and report writing tools. Organizations are often faced with difficult decisions on whether to build or buy BI/DW tools such as ETL software or OLAP programs.

Our experience in both large-scale enterprise data warehouses and small-scale niche data warehouses will help guide you through this process.
Epsolon Data warehouses are designed to perform well with aggregate queries running on large amounts of data. We develop the structure of data warehouses is easier for end users to navigate, understand and query against unlike the relational databases primarily designed to handle lots of transactions. Our Data warehouses enable queries that cut across different segments of a company's operation. E.g. production data could be compared against inventory data even if they were originally stored in different databases with different structures. We develop Queries that would be complex in much normalized databases could be easier to build and maintain in data warehouses, decreasing the workload on transaction systems.
