what is difference between Data base administrator and Storage administration?
469138
Normally a database admin is going to do just that, administer a database. That may be Oracle, SQL Server or the like. They may design databases, tune queries, perform backup and recovery operations, and help spec things out. A storage admin is going to deal more with actual drive setups. Raid mirrored arrays, making sure drive space is available for the network, space for email on exchange and the like. A database administrator shouldnt have to worry about drive space and a storage admin shouldnt be concerned with the technical aspects of what database is used. The two roles may crossover in small organizations, but as you have them listed, they are two very different roles.

If you configure policy using gpedit.msc. That mean all user affected. Dont care it Administrator or user all user will affected by the rule you set. For example you restric drive C then all user included Administrator cannot open drive C.\nYou can do this by choosing Admistatif Template on Computer Configuration and User Configuration on Group Policy (start -> run -> gpedit.msc)

Your question relates to how data is stored on disks in computer systems.   The software which controls this is called a file system.\n\nThe physical disk is divided into a large number of areas usually called sectors or blocks.   (Sometimes, a file system treats several sectors together as one logical "block").  A block is the amount of data which is written to or read from the disk at once.  It's also the unit in which space is allocated on the disk to individual files.\n\nBlock level access to a disk means that the program using that kind of access can read or write individual blocks on the disk.   When this is done, there is no file system providing protection or management of the space.   File access means that the file system software is used, and the program is oblivious to the blocks, and refers to data in terms of files.  In this case (which is the more common, by far), the file system worries about figuring out and controlling which blocks are used to store each file on the disk.\n\nTo summarize, block level access provides no protection and no bookkeeping of where things are.  File access lets the progra treat the disk at a higher, more logical, level and ignore the physical aspects.

Defining SAN:\n\nStorage networks are distinguished from other forms of network storage by the low-level access method that they use. Data traffic on these networks is very similar to those used for internal disk drives, like ATA and SCSI.\n\nIn a storage network, a server issues a request for specific blocks, or data segments, from specific disk drives. This method is known as block storage. The device acts in a similar fashion to an internal drive, accessing the specified block, and sending the response across the network.\n\nIn more traditional file storage access methods, like SMB or NFS, a server issues a request for an abstract file as a component of a larger file system, managed by an intermediary computer. The intermediary then determines the physical location of the abstract resource, accesses it on one of its internal drives, and sends the complete file across the network.\n\nMost storage networks use the SCSI protocol for communication between servers and devices, though they do not use its low-level physical interface.\n\n\n\nBenefits:\n\nSharing storage usually simplifies storage administration and adds flexibility since cables and storage devices do not have to be physically moved to move storage from one server to another. Note, though, that with the exception of SAN file systems and clustered computing, SAN storage is still a one-to-one relationship. That is, each device (or Logical Unit Number (LUN)) on the SAN is "owned" by a single computer (or initiator). In contrast, Network Attached Storage (NAS) allows many computers to access the same set of files over a network. It is now possible to combine the SAN and NAS using a NAS head, such as the gateway manufactured by ONStor\n\nSANs tend to increase storage capacity utilization, since multiple servers can share the same growth reserve.\n\nOther benefits include the ability to allow servers to boot from the SAN itself. This allows for a quick and easy replacement of faulty servers since the SAN can be reconfigured so that a replacement server can use the LUN of the faulty server. This process can take as little as half an hour and is a relatively new idea being pioneered in newer data centres.\n\nSANs also tend to enable more effective disaster recovery processes. A SAN attached storage array can replicate data belonging to many servers to a secondary storage array. This secondary array can be local or remote.\n\n\nSAN types:\n\nSANs are normally built on an infrastructure specially designed to handle storage communications. Thus, they tend to provide faster and more reliable access than higher level protocols such as NAS.\n\nThe most common SAN technology is Fibre Channel networking with the SCSI command set. A typical Fibre Channel SAN is made up of a number of Fibre Channel switches which are connected together to form a fabric or network.\n\nAn alternative, and more recent (2003), SAN protocol is iSCSI which uses the same SCSI command set over TCP/IP (and, typically, Ethernet). In this case, the switches would be Ethernet switches.\n\nOne alternative to iSCSI is the ATA-over-Ethernet or AoE protocol which embeds the ATA protocol inside of raw Ethernet frames. While a raw Ethernet protocol like AoE cannot be routed without something else performing the encapsulation, it does provide a simple discovery model with low overhead.\n\nConnected to the SAN will be one or more servers(hosts) and one or more disk arrays, tape libraries, or other storage devices. In the case of a Fibre Channel SAN, the servers would use special Fibre Channel host bus adapters (HBAs) and optical fiber. iSCSI SANs would normally use Ethernet network interface cards, and often specialized TOE cards.\n\nStorage area networks are of two kinds - centralized storage area networks and distributed storage area networks\n\n\nCompatibility:\n\nOne of the early problems with Fibre Channel SANs was that the switches and other hardware from different manufacturers were not entirely compat

administrative settings are there for a reason so you don't fuck up your works or schools computer.  If you really need access to something ask them, if you have a reason to access it (and no porn and games don't count) they will probably let you.

Whoa!  Bad things!\n\nThe superuser has ultimate power over the system, and therefore has complete control of the system, including the ability to completely demolish the filesystem.\n\nThe root of the UNIX filesystems is denoted by a single dot (".")\n\nIf a program with appropriate permissions executes the unlink (effectively a delete) command, it will remove the pointer to the root inode, and hence the entire filesystem will be lost.  Granted, the data will still be there but useless now.

Hi buddy,\n\nDatabase Management System is not a software or some kind of application. Its just a concept, It says how data are to be stored, maintained, modified or retrieved, etc.\n\nMs Access, Oracle, etc  are the softwares that come with the implementation of the Database Management System Concepts, where u can store ur data, retrieve it, delete it, etc. These softwares are bought by companies and are used for their database management.

Memory and hard drive space are 2 different things.  Memory is the amount of RAM that you have and hard drive space is the amount of storgae that you have.  \n\nI would place the programs on the fastest drive.  This is where you are doing all of the work so you want the best performance.

Go to My computer, right click on it and choose "manage" option. A console will open. Now choose "Disk Management" under "Storage" head. A complete graphical representatino of your hard disks (including partition informations and file system)will appear in front of you. As simple as that. Good Luck!

It depends on what type of operating program you have, but if you have Windows XP it is under the control panel, under User Accounts, change an account. If you only have one account, you should be the administrator already. If you have more than one, you need to be logged on to the administrator account to make any changes. Hope this helped.

You are the administrator.When it mentions administrator that is you. Register on the computer as the administrator,enter your name and serial number of the computer and other information about you and this will establish you as the administrator.

root is the main administrator account on linux and unix computers.  Or in simple words the person who runs that server.

difference: they are manufactured by different people, you can use them for the same purpose!!\n"MySQL is a database management system.\nA database is a structured collection of data. It may be anything from a simple shopping list to a picture gallery or the vast amounts of information in a corporate network. To add, access, and process data stored in a computer database, you need a database management system such as MySQL Server. Since computers are very good at handling large amounts of data, database management systems play a central role in computing, as standalone utilities, or as parts of other applications."\n\nWhat Is SQL Server 2005?\n\n"SQL Server 2005 is a comprehensive database platform providing enterprise-class data management with integrated business intelligence (BI) tools. The SQL Server 2005 database engine provides more secure, reliable storage for both relational and structured data, enabling you to build and manage highly available, performant data applications that you and your people can use to take your business to the next level."

Access is a file based database and Microsoft SQL Server a client server database.\nAccess utilises a File Server design while SQL Server employs a Client/Server approach. This is a fundamentally different architecture which has many, many implications.
