What is a HashTable Data Structure - Introduction to Hash Tables , Part 0
 
07:37
This tutorial is an introduction to hash tables. A hash table is a data structure that is used to implement an associative array. This video explains some of the basic concepts regarding hash tables, and also discusses one method (chaining) that can be used to avoid collisions. Wan't to learn C++?

02 How to configure Rang partition In oracle database
 
15:35
Now a days enterprises run databases of hundred of Gigabytes in size. These databases are known as Very Large Databases (VLDB). From Oracle Ver. 8.0 Oracle has provided the feature of table partitioning i.e. you can partition a table according to some criteria . For example you have a SALES table with the following structure Suppose this table contains millions of records, but all the records belong to four years only i.e. 1991, 1992, 1993 and 1994. And most of the time you are concerned about only one year i.e. you give queries like the following select sum(amt) from sales where year=1991; select product,sum(amt) from sales where year=1992 Group by product; Now whenever you give queries like this Oracle will search the whole table. If you partition this table according to year, then the performance is improve since oracle will scan only a single partition instead of whole table. This type of partitioning is useful when dealing with data that has logical ranges into which it can be distributed; for example, value of year. Performance is best when the data evenly distributes across the range

A Story of Indexes and Full Table Scans: Finding All the Red Sweets Part 1
 
08:43
"Why isn't Oracle using my index?!" is a common question people have when tuning SQL queries. In this episode Chris compares two methods for finding all the red candies from party bags he's prepared. He shows how these are like a full table scan and an index range scan. He goes on to compare the performance of these two approaches. He shows when a full table scan becomes more efficient than an index range scan and vice versa. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

Data Structures and Algorithms: Linked Lists, Trees, Hash Maps
 
09:18
Dr Jim Webber, Neo4j Chief Scientist, reviews the fundamentals of computer science from university apply to building databases. What are the cheapest data structures for reading? For insertion with limited write contention? For random access? As an amateur arborist, Jim also discusses reading from and writing to trees. In the next part of this short video, Jim talks about the choice of data structures used for implementing Neo4j. An important property of Neo4j is what we call “index-free adjacency” — Graph traversals in Neo4j are (Pointer Size) * (Offset), which is an O(1) implementation. Of course, we pick and choose other data structures and algorithms for high performance graph storage. We have trees, for example, to implement indexes to find the starting points for graph traversal very affordably. We use lists in Neo4j for scenarios with modest amounts of data to enable high write performance — property chains, as an example.

Post-Quantum Zero-Knowledge and Signatures from Symmetric-Key
 
33:34
We propose a new class of post-quantum digital signature schemes that: (a) derive their security entirely from the security of symmetric-key primitives, believed to be quantum-secure, and (b) have extremely small keypairs, and, (c) are highly parametrizable. In our signature constructions, the public key is an image y=f(x) of a one-way function f and secret key x. A signature is a non-interactive zero-knowledge proof of x, that incorporates a message to be signed. For this proof, we leverage recent progress of Giacomelli et al. (USENIX'16) in constructing an efficient sigma protocol for statements over general circuits. We improve this sigma protocol to reduce proof sizes by a factor of two, at no additional computational cost. While this is of independent interest as it yields more compact proofs for any circuit, it also decreases our signature sizes. We consider two possibilities for making the proof non-interactive, the Fiat-Shamir transform, and Unruh's transform (EUROCRYPT'12,'15,'16). The former has smaller signatures, while the latter has a security analysis in the quantum-accessible random oracle model. By customizing Unruh's transform to our application, the overhead is reduced to 1.6x when compared to the Fiat-Shamir transform, which does not have a rigorous post-quantum security analysis. We implement and benchmark both approaches and explore the possible choice of f, taking advantage of the recent trend to strive for practical symmetric ciphers with a particularly low number of multiplications and end up using LowMC. This is joint work with Melissa Chase, David Derler, Steven Goldfeder, Claudio Orlandi, Christian Rechberger, Daniel Slamanig and Greg Zaverucha.  See more on this video at https://www.microsoft.com/en-us/research/video/post-quantum-zero-knowledge-and-signatures-from-symmetric-key/

Diagnosing Your Application on the JVM
 
50:50
Have you ever had an application behave in an unexpected way and wondered what tools there are for diagnosing it? This session covers all the tools that ship with the JDK that can be used to diagnose application problems. It looks at a wide range of tools and problems. Among other things, it shows how to monitor heap usage, check for deadlocks, analyze thread dumps, and look at heap contents. The session focuses on demos of the tools and practical tips but also covers the background and details of the implementation of the tools. It also gives a sneak preview of what is coming down the road. The goal of the session is to provide an overview of the available tools and what you can use them for.

AWS Webcast - Data Modeling for low cost and high performance with DynamoDB
 
01:00:02
Efficient schema design reduces cost and eliminates barriers to scalability. This requires a different approach to data modeling, with a focus on optimizing for usage patterns rather than merely describing objects. In this session, you will learn best practice techniques for minimizing payload size and modeling one-to-many relationships in DynamoDB, leveraging the versatility of hash+range primary keys. These methods have been used extensively by customers with substantial workloads on DynamoDB, enabling them to grow their applications quickly and cost-effectively.
