新功能


SAS® 9.4 has something for everyone. High-performance analytics. The ability to deploy in cloud environments. Standardized data management. It's more of what you need. And more of what you’ve come to expect from SAS.

Get up and running faster than ever. The unified SAS 9.4 platform reduces the time required to install, manage and maintain SAS deployments.

Simplify the user experience – from deployment, to administration, to one-to-one user interaction. Remove technology and skill barriers, so everyone can gain analytic insights from all relevant data.

Apply discoveries and insights to solve problems and drive innovation. SAS 9.4 takes advantage of distributed computing and storage technologies, and open standards. Arm developers with new programming languages that deliver SAS analytics directly to the data – no matter where it resides.

Gain ultimate flexibility in how you deploy SAS. With SAS 9.4, you can install solutions on-site. Or have SAS host the deployment. Or deploy SAS in a private or public cloud environment. It's your choice.



Performance


• High-performance features. A SAS 9.4 upgrade includes high-performance features that break analytic tasks into pieces to speed up processing. But as your data grows and you need more complex analyses, your high-performance code automatically scales to run in a distributed environment. No further action from you is required.
• Add prescriptive analytics to your arsenal. We enhanced SAS Visual Analytics with scenario analysis and decision trees, so now you can predict with more precision. Interactive decision trees are especially cool because they visually show you what’s most likely to happen, before it happens – in just seconds.
• Deliver results when and where needed. New APIs make it even easier to integrate SAS into your business processes. These interfaces help you quickly create analytic applications that deliver answers when and where needed. And mobile delivery options make it easy to deliver SAS data visualizations to the iPad®, iPhone® and Android tablets.


Management


• Management made simple. It’s easier to track things you can see – environments, solutions and servers. With SAS Environment Manager, you can visualize and easily understand your entire SAS deployment using advanced monitoring and management capabilities.
• Stop trouble before it stops you. Everyone's happier when things are working. With SAS Environment Manager, you can keep tabs on the details when it works best for you – daily, weekly or monthly – and make adjustments before your users even know there's a problem.
• See what matters to you. Keep an eye on what’s most important to you with customizable dashboards. The SAS Environment Manager collects alerts, notifications and data from your servers and presents that information in a dashboard you can customize easily. You can also create plug-ins that tie them directly into the dashboard.


Deployment


• It's cloudy. And that's cool. Your data is already in the cloud. Naturally, you want to run your applications in the cloud, too. No problem – just install SAS in the cloud and go. Or, we can handle those details for you in the SAS Cloud.
• It's a private matter. Many organizations opt for private clouds where applications and data remain on-site. To speed deployment and create a highly available environment, SAS Grid Manager allows you to allocate and manage jobs to run in pieces across a shared grid. This helps you balance workloads, optimize hardware capacity, improve performance and adjust the environment on the fly. We also provide hosted and managed cloud options if you want a private cloud environment – but don’t want to build, manage and maintain it yourself.
• No more hardware headaches. Start using SAS right away without having to install and configure any hardware. We'll handle those details. SAS Cloud Analytics gives you rapid access to SAS analytics tools and solutions. We’ll help you prepare and move your data to the SAS Cloud. You can add more data later at your convenience. We perform all hardware and software management – guaranteeing you have the most current version of SAS software at all times.


Availability


• No assembly required. Now you can get value from your analytic deployments faster than ever. Fewer software integration points reduce costs and simplify installation, maintenance and support. Even better, middle-tier components are provided. Everything you need to run robust web and cloud applications is included with SAS 9.4.
• No time for downtime. Who has time for data loss and system downtime? We designed SAS applications to be available when you need them, 24/7. Clustering your midtier and metadata servers provides a more highly available platform. If one node in the cluster fails, users can continue working using the remaining components.
• Fine-tune your workloads. Our midtier server meets the precise requirements of SAS workloads without excess overhead. Because it’s optimized for SAS workloads, you can improve your operational efficiency and scale to meet the need for increased computing power. These are also the capabilities that enable SAS 9.4 to deliver a cloud-friendly platform.





Business Executives

Identify opportunities, and find your own answers – fast. And empower others to do the same. Interact directly with visualizations to refine your analysis, and dive into data more deeply to illuminate insights and opportunities. A wide range of report delivery options, including mobile, gives you access to powerful analytics and reporting no matter where you are.




IT Experts

Lower your risk with a platform that's easier to install and manage. And it’s more secure. We eliminated the complexity of integration with external software and provided built-in redundancy of critical server components. It’s more resilient – designed to keep running when things go bump in the night. And on-demand cloud offerings give you more options for deploying analytics.




SAS Administrators

SAS Administrators Monitor and address performance concerns before your users are even aware of them. You can easily look into the overall performance and health of the individual servers you manage. And gain insights into the usage patterns of SAS workloads.
