ABOUT US:

We design and develop the data storage and processing engine for the Oracle Database and the Exadata Database Machine, exploiting innovative and emerging technologies like NVRAM (Non-Volatile Memory), RDMA, and SIMD / GPU processing. Our focus is on big-data, in-memory data management, high performance OLTP and hardware-software co-design for real-time in-memory analytics. Some of the highlights of this team are as follows:

a) Delivering Oracle Database In-Memory Option, announced by Larry Ellison at the September 2013 Openworld conference in San Francisco. This new In-Memory Database technology provides the ability to process hundreds of billions of rows per second, and is one of the most visible areas in the Oracle Database at present.

b) Industry-leading innovations in Data Management with 100 patents awarded in the last few releases.

c) Active contributors in the database community, regularly publishing papers in conferences such as VLDB, SIGMOD, and ICDE. Recent research publications span the areas of Database In-Memory, Real-time In-Memory Analytics, Database File System, Temporal Databases, and Oracle SecureFiles.

d) Responsible for leading edge innovations for Exadata: Smart Scan, Hybrid Columnar Compression and Columnar Flash Cache.

We are one of the fastest innovating teams in the industry, with our technology regularly featured within the Top 5 features in the database by external sources for multiple releases. Our innovations extend the Oracle Database to be far more than just a data processing framework - for example, Flashback / Temporal technology allows the Oracle database user to travel back in time, Secure Files and the Database File System allow Oracle to serve as a very high performance unstructured content repository, Advanced Compression and Advanced Data Optimization allow Oracle Database to facilitate the role of an automatic broker for information life-cycle management. Our largest customers entrust their data management needs to the Oracle Database because of technologies built by this team.

The Data Technologies group covers three areas:

1. Data Storage

The Data Storage group designs storage and access structures for the entire database, including in-memory columnar data formats, b-tree and bitmap indexes, heap tables, index-organized-tables, secure files and lobs, hybrid columnar storage formats, etc. We also design blazing fast access paths for retrieval of all data stored in the database (including relational, XML, text, spatial and graph data), by leveraging techniques such as SIMD vector processing, in-memory JSON processing, RDMA access, etc. We are also responsible for making the storage sub-system more intelligent, thus allowing the database to push predicate evaluation, projection, aggregation etc. into the storage layer, effectively moving the evaluation logic closer to the data, resulting in accelerated query performance.

From the constantly changing landscape of processor and storage technology to new application requirements (such as XML, JSON, media streaming, indexing), this is a pivotal group that has the charter of providing technology leadership for the Oracle Database server. Our recent efforts have spanned the areas of in-memory columnar databases, compression, encryption, file-system caching, and providing extreme availability in cloud-scale distributed environments, where the database spans clusters comprising hundreds of nodes, but provides a single system image to the end user.

2. Transaction Processing

The Transaction Processing team develops the engine for transaction processing for the database and the mid-tier. This team is responsible for transaction locking, multi-versioning concurrency control, parallel and distributed coordination protocols, cache fusion protocols for clusters, self-learning undo management, and transaction recovery. Ongoing and future projects are in the areas of in-memory column store maintenance, continuous query notifications, cluster-wide distributed transactions (transaction fusion), historical data store, flashback transaction, auto correcting undo management, and application integration.

3. Space Management

Space management is a fundamental component of the Oracle Database that provides an abstraction to the database storage subsystem. Space requirements for the database are primarily of two kinds - temporary scratch space required to store intermediate results generated in the database and persistent storage used to store user data. From managing the temporary space for sorting a terabyte of data to finding the best slot in a petabyte volume disk for storing the next piece of employee payroll information, intelligent space management is one of the foundations for high-performance OLTP and data warehouse systems. Developing an efficient storage management component that works for all data types and also scales for several hundred thousand concurrent users is the mission of the space management team.
