Business challenge story

Growing pains

Molina Healthcare specializes in providing comprehensive medical care and insurance services to meet its members’ complete healthcare needs. By retaining a sharp focus on excellent service, the company has achieved enviable growth in recent years.

As Molina grew, soaring data volumes in the production databases supporting its medical claims application platform began to impact the company’s database size and storage costs.

Trinh Montrenes, Principal Architect at Molina, explains: “Our core systems provide functionalities that are crucial to our ability to successfully deliver quality healthcare services to our members. We manage systems that encompass every facet of member services, claims processing, payment, quality assurance and provider management.”

She continues: “Like other companies, we face the challenge that the volume of data we manage is growing significantly over the years. When you have data in your production systems that is not used, or is only used infrequently, it can incur significant storage expenses, performance degradation, and maintenance overhead.”

However, slimming down those systems also posed a significant challenge, because the complex structure of modern relational databases makes it difficult to remove old or infrequently used records in a clean and consistent manner.

Every time a row of data is moved from one database to another, it is vital to understand all the relationships and dependencies that the row has with rows in other tables. If the referential integrity of either the source database or the target database is broken, it may lead to orphan records in the production system and unrestorable data in the archive.

Marc Hebert, Chief Operating Officer at Estuate, an IBM Business Partner specializing in information lifecycle governance that worked with Molina on this project, comments: “With relational databases, it’s always easier to put data in than to pull it out. You have to do it very carefully to make sure you extract the whole business object intact, and don’t leave orphaned records that can impact the stability of your application.”

The cost savings on storage using IBM InfoSphere Optim have enabled us to achieve a positive return on our investment within the first year.

Transformation story

Finding the cure

After checking the vital signs of solutions from several vendors, Molina deployed a data archiving solution based on IBM InfoSphere Optim Archive. Estuate provided support during the implementation.

“Based on Gartner research at the time, Optim was a leader in the data management space in its capacity to archive both structured and unstructured data,” recalls Trinh Montrenes. “We also saw IBM as a well-established company with strong presence and industry longevity. We enlisted the support of Estuate following a recommendation from IBM. We found the Estuate team to be very responsive, flexible and enthusiastic. It was a pleasure to work with them.”

First, Estuate helped Molina use the IBM solution to create a standard template of business rules and policies that define the criteria for when and how a record should be archived.

Next, the teams worked together to develop a custom data model that would define each type of business object and ensure that the relevant related records would be handled correctly during the archiving process. This was a collaborative effort between the Estuate team and subject-matter experts from across Molina’s business.

Trinh Montrenes comments: “We recognized that understanding data dependencies and how they impact the business process was crucial to the success of the project. Estuate did a good job of helping us clearly define and document our requirements to ensure that our objectives would be met.”

Following an initial process to archive its backlog of historical data, Molina is now able to archive its data on a quarterly basis, using its archiving template and data model to identify data no longer needed to be stored in the production environment. The solution leaves any open transactions, cases, claims and documents untouched.

Results story

Slimmer databases for a healthier outlook

With the IBM solution, Molina has gained a reliable, consistent method for archiving records in its production database – helping to ensure full referential integrity for its data.

Trinh Montrenes says: “Reducing the size of our production database helps us maintain good performance in our medical claims applications, while reducing the amount of time and effort we need to spend on database maintenance and indexing. For the first time, we are able to delete and archive records from production in a robust and consistent process. And most important, the deleted records can reliably be brought back into the production database again at a later time, if we need them.”

She concludes: “From a financial perspective, the archived data can now reside on more economical storage devices. In fact, the cost savings on storage devices alone have enabled us to achieve a positive return on our investment within the first year, with even more savings forecast for the future.”
