If you are a company or organization in the health services industry and you work with personal patient data, then you have most probably heard about HIPAA compliance. The Health Insurance Portability and Accountability Act (HIPAA) is a law passed in 1996 by US Congress that sets standards and protocols for the protection of patient data in the healthcare industry. Many of our users and customers asked us about building HIPAA compliant applications ... Read More

Feed: Blog – ArangoDB. Author: Willi Goesgens. This is an update of the 2016 blog post How to put ArangoDB to Spartan-Mode. A lot of things have changed in the last years. We moved our API implementation from JavaScript to C++. ArangoDB now has a new (default) storage engine, namely RocksDB instead of MMFiles. RocksDB is a great storage engine. However, it also trades memory for speed. If you start with the default configuration you might end up with using much more memory for ArangoDB than expected. Therefore let’s focus on our new storage engine, and make a configuration to ... Read More

Feed: Blog – ArangoDB. Author: Daniel Larkin-York. Sometimes we want sorted output from a query and, for whatever reason, cannot use an index to do the sorting. In ArangoDB, we already cover this critical case with finely tuned query execution code. Sometimes though, we do not need to return all output, and follow our SORT clause with a LIMIT. In ArangoDB 3.4 and earlier, we did not handle this case any differently from returning the full data, at least with respect to sorting – we would sort the full input, then apply the limit afterwards. In many cases though, it is possible to ... Read More

Feed: Blog – OrientDB. Author: Leann. More than 2.5 quintillion bytes of data—as much as 250,000 times the printed material in the U.S. Library of Congress—come into existence every day. What this data means for the average enterprise is opportunity: the opportunity to improve fraud protection, compliance and personalization of services and products.But first, you need to make sure you are working with the right data and that your data is consistent and clean. While data governance itself is not a new concept, the need for significantly better data governance has grown with the volume, variety and velocity of data ... Read More

Feed: Blog – OrientDB. Author: Leann. Today, banks, credit unions and other financial services firms must cross many data chasms to keep customer information secure, accessible and functional for modern service application development and risk detection. Yet, the intertwined nature of aging data architectures and tangled data lineages make rapid application development difficult to accomplish—and buries organizations in technical debt.What is Technical Debt? Technical debt refers to the financial, time and risk costs of running services and applications from outdated system design or IT infrastructure. Within financial services firms, IT architecture is built upon multiple databases and software systems in ... Read More

Feed: Blog – OrientDB. Author: Leann. The power of graph database solutions means that creating data and finding relationships between data sets is not constrained by defined data classifications, formats, storage locations or original data structure.By storing and monitoring relationship data, graph solutions enable organizations to act on changes to their data model without the limitations of a set database structure, known as schemas. A database that isn’t limited to one schema type also simplifies data modeling and querying of connected data. Although graph solutions support schema-less use, you might still want to use a schema to enforce some structure ... Read More
