Database tools

August 6, 2009
We have so many database tools. Simplify and automate your database development process, design, explore and maintain existing databases, build compound SQL query statements, manage database user rights and manipulate data in different ways.
There are so many database tools available.
1. Data Quality Tools
2. Database Administration Tools
3. Database APIs & Connectivity Components
4. Database Comparison Tools
5. Database Development Tools
6. Database Documentation Tools
7. Database Engines
8. Database Management Systems
9. Database Query Building Components
10. Miscellaneous Database Tools
11. Online Analytical Processing (OLAP) Components
Data Quality Tools:
Data quality tools are used in data warehousing to ready the data and ensure that clean data populates the warehouse, thus enhancing its usability. Use these tools to keep your data in great condition. Ensure consistency, cleanse, remove duplicates, reformat and more .There are so many quality tools are available in the industry. Using this tool, we can make or keep clean up our database. In addition, to avoid the redundancy of data.Data quality tools generally fall into one of three categories: auditing, cleansing and
These tools are used to audit the data at the source, Transform the data so that it is consistent throughout the warehouse, segment the data into atomic units, and ensure the data matches the business rules. The tools can be stand-alone packages, or can be integrated with data warehouse packages. Data flows from the source database into an intermediate staging area, and then into a data warehouse. Different tools can be used at each stage.

Some of the quality tools as follows:

Platform Support
WizRule Inc.
Database Administration Tools:
A person who is responsibilities for the environmental aspects of the database is known as database administrator. He has so many responsibilities in the database environment as follows.
  1. Recoverability
  2. Security
  3. Availability
  4. performance
  5. Duties of DBA
1. Recoverability (crating and testing Backups)
Suppose any error occur in the database like data loss or hardware filer. The Database administrator can bring the data from data warehousing unit. Recoverability activities include making database backups and storing them in ways that minimize the risk that they will be damaged or lost, such as placing multiple copies on removable media and storing them outside the affected area of an anticipated disaster. Recoverability is the DBA¬タルs most important concern.
2. Security :
The DBA finds about the access restrictions to be defined and defines security checks accordingly. Security means that users¬タル ability to access and change data conforms to the policies of the business and the delegation decisions of its managers.
Basic securities:
1. Server security
2. Database connection
3. Restricting database access
There are many ways to prevent open access from the Internet and each database system has its own set of unique features as well as each OS. Therefore, I am merely going to touch on a few methods.
1. Trusted IP addresses
2. Server account disabling(password Lock)
3. Special tools
Oracle Advanced Security Transparent Data Encryption (TDE) makes encryption of sensitive data simple with no changes to the existing application code
3. Availability:
Availability means that authorized users can access and change data as needed to support the business. Increasingly, businesses are coming to expect their data to be available at all times .The IT industry has responded to the availability challenge with hardware and network redundancy and increasing online administrative capabilities.
4. Performance:
Designing the database and database interaction so that it performs to be required: On the database side, there are four items of PRIMARY importance
1. Design your database properly – a normalized database design is usually a better starting point of designing. Occasionally you may have to demoralize something – but only do so as a result of testing showing the need – and AFTER optimizing the database in the normalized design.
2. Make the database better to work – Building SQL queries and stored procedures that deliver data as close to your “final product” as possible. This means that you should minimize the number of round trips – for instance, by minimizing the number of queries to obtain a set of data.
5. Duties of Database administrator:
1. Installation of new software :it is a regular job of the DBA to install new versions of DBMS software, application software, and other software related to DBMS administration.
2. Configuration of hardware and software with the system administrator :In many of the cases the system software can only be accessed by the system administrator. In this case, the DBA must work closely with the system administrator to perform software installations, and to configure hardware and software so that it functions optimally with the DBMS
3. Security administration :one of the main duties of the DBA is to monitor and administer DBMS security. This involves adding and removing users, administering quotas, auditing, and checking for security problems.
4 Responsible for the administration of existing enterprise databases and the analysis, design, and creation of new databases.
1. PhpMyAdmin 2.11.4 for MYSQL
2. SQL Maestro  for Oracle Maestro 6.11,MS SQL Maestro 8.1 , PostgreSQL Maestro 7.12 released
