Registering a challenge

Booking a holiday home online can be a pain, with multiple agencies making various offerings, and no easy way to compare prices. On top of this, the Belgian government recently introduced legislation requiring all holiday accommodation be officially registered, placing administrative strain on real estate agents.

Franky Deleu is Chief Information Officer at ORIS—the representative partner for the Belgian real estate industry for e-Government initiatives and industry-wide IT services and partnerships, which also manages the sector’s central data systems. He explains: “This year, the Belgian government has brought in new legislation, requiring all holiday homes to be registered and licensed by the government. That obviously creates a lot of extra work for real estate agents, who now need to register every rental property in their portfolio. There’s also the issue of how estate agents promote themselves online. With so many property websites out there, it can be hard for agencies to promote themselves across all of them.”

In addition, agents faced challenges with processing customers’ requests. ORIS had previously developed an online booking system using another service provider, but the system was too slow to be effective.

“The main issue was price and occupation time queries,” Franky Deleu explains. “Customers would want to view a property, but the existing solution was just too slow in checking the central database, and struggled to load the information fast enough. Customers would get bored of waiting, and that meant the solution never really took off. We realized that, in moving to a new solution to help agents handle the new government legislation, we also had an opportunity to improve our customer service, and help agencies with online promotion.”

The market adoption rate is higher than we ever could have predicted—last time we checked, 90 percent of the Belgian market was using it.

Working with IBM Business Partner CD Invest, ORIS created the Lazee platform, an online portal which automatically registers holiday rental properties with the government, as well as providing an online booking platform for consumers, by centralizing data from the majority of agencies across the country.

Koen Decorte, Business Partner at CD Invest, explains: “The Lazee platform offers secure connections with the government’s web platform, the VLIS, so agencies can make sure they are complying with property registration requirements. The system automatically validates all the addresses in an agency’s portfolio, and also generates a PIM number for each new property.

“What’s more, the Lazee platform works as a portal for several different holiday booking websites, which means agencies don’t have to create separate listings on each one. There is total coordination of property data, so we avoid double bookings. As soon as a customer reserves a holiday home, even if they do it over the phone or in a high street branch, the system automatically takes it off all the travel websites running on Lazee for those dates.”

The front-end of the solution runs on a Linux partition on an IBM Power Systems™ S814, with the core database and some other elements running on IBM i on the same physical server, alongside ORIS’s core business systems. “It’s a mutually supportive operation,” continues Koen Decorte. “All the data and the photos for each property reside on the i, as well as some of the system logic. But then you have some features, like local sights and restaurant recommendations, that are added by the end consumers, and those features are all running in Drupal on Linux.

“We’re seeing excellent performance with this combined system—it’s loading data and responding to queries much faster than the previous solution ever did. What’s more, the new web portal is completely integrated with the back-end systems running on IBM i, many of which our client has been successfully using for a number of years. In this way, the solution combines tried-and-trusted systems with the latest in open source innovation to create new value.”

In addition to Drupal, the solution makes use of several other open source packages including Curl and ImageMagick, and takes advantage of the IBM Db2® driver for Linux to query the integrated Db2 database on IBM i. All webservices were developed using RPG and SQL on IBM i – the RPG applications send responses to the front-end in the form of JSON documents.

We have such great support from CD Invest, and there’s so much potential with the i solution, that we feel really energized to keep being ambitious, and make life as smooth as possible for both estate agents and end consumers.

Results Story

Sunny days ahead

With the Lazee platform running on IBM Power Systems in place, ORIS has seen far more interest in its online real estate solutions.

“We’ve seen a huge spike in demand since we moved the web portal to run on IBM i on our Power S814 server,” says Franky Deleu. “The market adoption rate is higher than we ever could have predicted—last time we checked, 90 percent of the Belgian market was using it to register and promote their holiday homes, which means property listings can be coordinated nationwide in a way they weren’t before.

“The solution also delivers huge time savings in terms of compliance. It used to take agents weeks to manually register each property with the government—now each registration can be completed within days, or even hours. This frees up agents to focus on other more value-adding tasks.”

Looking to the future, ORIS plans to expand the Lazee platform even further, and create greater efficiencies through automation.

Franky Deleu concludes: “We’re currently exploring the automation of contracts, payments, monitoring of cleaning and repairs to each property, and even systems to manage insurance policies and report maintenance figures directly to agencies.

“We have such great support from CD Invest, and there’s so much potential with the i solution, that we feel really energized to keep being ambitious, and make life as smooth as possible for both estate agents and end consumers.”
