Nice Systems (NICE), a maker of contact center software, has agreed to buy Causata, a provider of customer behavior analytics software. Ideally, the two technologies combined could provide a real-time picture of what a customer has been up to the moment he calls a company's call center.

The merger, announced Wednesday, would allow Nice to integrate Causata's analytics into its Customer Engagement platform, which tracks companies' interactions with their customers. Causata is based in San Mateo, Calif.

The merger will allow Nice to integrate Causata's database of customer interactions into its software, allowing the company to create customer profiles and track interactions through several channels, NICE said in the news release.

"The acquisition of Causata is another important step in executing on our strategy to help organizations get closer to their customers by providing real-time solutions which address the entire customer journey across touch points," said Zeevi Bregman, president and chief executive of Nice, in the news release.

The companies expect the merger to close in a few days.
