You want to know the full form of i p s?
The full form of IPS:-Indain Police Service..... Hope u got it....
What is the fundamental questions would you ask when designing forms and reports?
Without knowing the entire background to the form, can I -your customer- complete it without detailed help text? If not, consider using simpler/more common terms for frields.
Does it make sense considering your database design? If not, reconsider the form or your database.
Is it easy to program? If not, it could be more complex to a customer than you may think, or may be an incorrect way of approaching the problem at least.
I can help you with that. In my case, I had neither experience nor certification. Currently I am a database administrator making $70,000/yr. How? The key is in the title "Database Administrator." What does it mean? As it turns out it has two definitions:
1) a person who maintains a database server, the hardware and software that the database runs on, administers its users access rights, and tunes its performance for the many different users of the server 2) a person who creates databases, tables, views, and SQL statements and links those databases and tables with other technology (like web sites) (as a back-end developer), and reporting tools (like Crystal Reports or Excel, or what-have-you). I am the 2nd kind. I found my job through the government as a contractor. I do not think I could have landed the job myself, though; the secret is that a normal civilian cannot apply for a government contract and expect to win it. Instead, get hired with a contracting company that already owns those contracts and needs people to fill them. That is where the money is.
Good luck! May you find job karma.
Whether sms is connectionless or connection oriented?
I would say it is connectionless, as it sends the message to the person to revive it without establishing the connection first so there's no way to know if they revived it.
A simple query would do something like just list of data in the table, without any other elements such as conditions or sub-queries or being a parameter query or using functions or formulas. So if all you wanted to do was list of all the names of people in a table, that would be a simple query.
What is the Slogan for oracle?
Information driven(PRESENT)
For the Oracle Database: "Can't break it, can't break in"and "Unbreakable"
As of 2008: "The Information Company"
As of 2010: "Software. Hardware. Complete."
As of late 2010: "Hardware and Software, Engineered to Work Together"
What is object oriented classes and the relationship between them?
I would need more info on the specifics of what you are asking, since this is a pretty broad question.
A class is a definition for the rules an object follows.
There can be lot's of relationships between classes in loads of different ways, for example, in the browser each tab is an object, and within each tab is a page, which is an object, inside that object is the document object, which contains elements on the page, all objects, and each object has more objects as it's children defining things like attributes, image urls and text content.
Or you could mean that an object is built on another, for example using the browser again as an example all elements on the page are children to the same basic build, but each one has different features and defaults, an input box is still a HTML element, but it contains features others may not have. they do however have the same basic structure.
Oracle PFT = Oracle Profitability Manager which is a tool used in the financial end.
Where assignments will be stored in pega rules database?
Workbasket assignments are stored in pc_assign_workbasket. Worklists assignments are stored in p_assgn_worklist.

1000 kb in a mb
1000mb in a gb
1000 gb in a tb(terrabyte),and so on,never stops!
How do you set a downloaded cursor as your cursor?
If you already downloaded the cursor heres what to do: (1 Go to the start menu on your pc (2 Click settings and go to control panel (3 Click printers and other hardware (4 Then click mouse (5 Click pointers (6 Click browse: Click on the file (7 finish with a smile (^-^)
Yes. Conditional distribution applies to fractions of rows/columns. Marginal distribution applies to the totals for each row/column
Why must create user in oracle todo your work in oracle?
A user in Oracle corresponds to a schema.
Objects, such as table and indexes, must exist within a schema.
Without creating a user/schema, use of the database will be limited to the built-in schemas and objects, such as the one-row DUAL table and standard PL/SQL packages.
Difference between network model and hierarchical model?
The network model is a database model conceived as a flexible way of representing objects and their relationships. Its original inventor was Charles Bachman, and it was developed into a standard specification published in 1969 by the CODASYL Consortium. Where the hierarchical model structures data as a tree of records, with each record having one parent record and many children, the network model allows each record to have multiple parent and child records, forming a lattice structure. The chief argument in favour of the network model, in comparison to the hierarchic model, was that it allowed a more natural modeling of relationships between entities. Although the model was widely implemented and used, it failed to become dominant for two main reasons. Firstly, IBM chose to stick to the hierarchical model with semi-network extensions in their established products such as IMS and DL/I. Secondly, it was eventually displaced by the relational model, which offered a higher-level, more declarative interface. Until the early 1980s the performance benefits of the low-level navigational interfaces offered by hierarchical and network databases were persuasive for many large-scale applications, but as hardware became faster, the extra productivity and flexibility of the relational model led to the gradual obsolescence of the network model in corporate enterprise usage.
What is a supermarket checkout system?
All these processes are very helpful for the purposes of dealing with an individual customer's purchases. However, when computers are linked in a network, many new uses are possible.
Now, I am going to draw a different system boundary. The components of this supermarket checkout system are the checkout terminal, the network and the database server. A database server is used to make the data in databases available to other computers on the network, and therefore to users. You met a specialised form of database server in Section 14.2: the FirstClass server. In the following sections, I'll focus on the network first and then look at the database server.
You might be wondering about the users of the system: the customer and the checkout operator. For the time being, we are focusing on the computers and network, rather than thinking about the end users.
What are the five types of knowledge produced from data mining?
• Acquired knowledge comes from outside the organization. In some
cases, an organization purchases the knowledge from another source.
Similarly, information can be leased or rented. For example, some "rented"
knowledge comes from consultants. Institutional research relies heavily on
rented knowledge such as U.S. Census Data, Integrated Postsecondary
Education Data System (IPEDS) files, research methods, to name a few.
Davenport and Prusak note that "originality is less important than usefulness"
in acquired knowledge.
• Dedicated resources are those in which an organization sets aside
some staff members or an entire department (usually research and development)
to develop within the institution for a specific purpose. These dedicated
resources are usually protected from competitive pressures to develop
profitable products. Offices of institutional research are by themselves good
examples of dedicated resources to the extent that they generally serve specific
purposes, which are not duplicated or shared by other departments and
offices. This is particularly true when institutional research functions are
centralized within one office.
OVERVIEW OF KNOWLEDGE MANAGEMENT 11
• Fusion is knowledge created by bringing together people with different
perspectives to work on the same project. The resulting projects represent
more comprehensive expertise than possible if members of the team represented
one perspective. But Davenport and Prusak note that fused knowledge
often involves conflict, and a team needs time to reach a shared knowledge
and language. Cross-functional teams are becoming popular in higher
education institutions and are examples of fusion. Institutional researchers
are often called upon to participate in various teams due to their expertise.
• Adaptation is knowledge that results from responding to new processes
or technologies in the market place. The expansion of on-line instruction
offered by higher education institutions is an example of adaptation.
• Knowledge networking is knowledge in which people share information
with one another formally or informally. Knowledge networking often
occurs within disciplines; for example, an institutional researcher communicating
with another.
Which of these is used to open an database?
Depends on what kind of database you are opening. I only know of OLEDB (Access) database.
Dim conn as New System.Data.OledbConnection
conn.ConnectionString="C:\a.mdb"
conn.Cpen()
'code goes here
conn.Close()
That's how you open an database.
How do you toggle the BIOS reset jumper?
The BIOS rest jumper is toggled by placing the jumper of the specific jumper pins. This causes the connection to close the circuit and trip the internal reset.
What are the advantages of distributed systems?
its is the risk sharing burden .....................it gives u infrastructure such as storage facility, transport facility, ...............it gives u first hand information from the market.......it builts your relationship.........it is usefull for market mapping..............
Single-user database support only one user at a time
Why DBA understand query optimization?
he is the main person for the data administration for the relational database management systems. therefore, he needs to understand the query plan and be able to suggest the suitable query plan that would satisfy the query.
