Sql Dba Tools

Presumably every DBA would like to challenge the data import time, the shorter the work efficiency, the more sufficient to prove their strength. In the actual work sometimes need to import a large amount of data into the database, and then for various program calculation, this article will recommend a challenge 4 seconds limit to let millions data into SQL Server experiment case. This experiment will use the 5 method to complete this process, and detailed records of the various methods of time spent. The tools used are Visual Studio 2008 and SQL Server 2000, SQL S ...

With regard to NoSQL and SQL, it is well known that NoSQL only allows data to be accessed in restricted predefined modes. For example, DHT (Distributed Hash Table) is accessed through the Hashtable API. Other NoSQL data service access modes are also restricted. Scalability and performance structures are therefore predictable and reliable. In SQL, access patterns are not known beforehand, SQL is a common language that allows data to be accessed in a variety of ways, and programmers have limited control over the execution capabilities of SQL statements. In other words, in s ...

What is the real difference between NoSQL and SQL? Essentially, because different access patterns lead to differences in NoSQL and SQL scalability and performance. NoSQL only allows data to be accessed in restricted predefined modes. For example, DHT (Distributed Hash Table) is accessed through the Hashtable API. Other NoSQL data service access modes are also restricted. Scalability and performance structures are therefore predictable and reliable. In SQL, access patterns are not known beforehand, and SQL is a ...

MAPR today updated its Hadoop release, adding Apache Drill 0.5 to reduce the heavy data engineering effort. Drill is an open source distributed ANSI query engine, used primarily for self-service data analysis. This is the open source version of Google's Dremel system, which is used primarily for interactive querying of large datasets-which support its bigquery servers. The objective of the Apache Drill project is to enable it to scale to 10,000 servers or more servers, while processing in a few seconds ...

According to the IDC survey, global data volumes reached 1.2ZB at the end of 2010. By 2020, global electronic devices will have a 30 times-fold increase in data storage, up to 35ZB (equivalent to 1 billion 1TB of hard disk capacity). But for the prepared enterprise this is undoubtedly an information gold mine, with the progress of data mining technology, valuable information will become easy to obtain. With the advent of the large data age, data storage, data mining, and processing and analysis of large data-related technologies are more concerned than ever. Big data is becoming the cornerstone of enterprise development, and gradually ...

How fast is the tide of big data? IDC estimated that the amount of data produced worldwide in 2006 was 0.18ZB (1zb=100), and this year the number has been upgraded to a magnitude of 1.8ZB, which corresponds to almost everyone in the world with more than 100 GB of hard drives. This growth is still accelerating and is expected to reach nearly 8ZB by 2015. The storage capacity of the IT system is far from adequate, let alone digging and analyzing it deeply. In this article, Baidu Chief scientist William Zhang, Teradata Principal customer Officer Zhou Junling, Yahoo!...
