Create a standalone and portable database

Until now, i have been coding my programs in visual basic 6, and i am used to create my desktop applications building an exe file and attaching a .dbm database beside it.
That way, it was easy to port them to another computers.
Now im trying to do something similar with java, and some people recommended me to use JavaDB - But i think i cannot achieve the same portability as i described i was using until now.
Does anyone have any idea on how to do this?
Thanks!

Yes, JavaDB is another embeddable database. It's delivered with the JDK, if I remember correctly (never used it). Be aware that it's not installed with the JRE, however. So if you want to distribute your application, you'll have to distribute the JavaDB jar file as well.
A third candidate would be H2.

How can i create a new and tableless database using database configuration

How can i create a new and tableless database using database configuration
Just don't install the sample schemas. See the installation guide
http://docs.oracle.com/cd/E11882_01/server.112/e10831/installation.htm
Using the Database Configuration Assistant
When you install Oracle Database with the Oracle Universal Installer, the sample schemas are installed by default if you select the Basic Installation option. Selecting the sample schemas option installs all five schemas (HR, OE, PM, IX, and SH) in the database. If you choose not to install the sample schemas at that time, you can add them later by following the instructions in section "Manually Installing Sample Schemas".
Choose a custom install and don't install the sample schemas.
All other schems/tables installed are REQUIRED by Oracle

Creating a Trigger and some Database Design

Here is the scenario, we have the following tables
Orders, OrderDetails, Products, ProductsToInventory, Inventory, and InventoryDetails
Orders is where the orders are saved and their details are in OrderDetails (orderdetails has a column called Type and that type can either be a product, inventory, shipping, fee, so that we can distinguish what each one is in the order)
Products are the products we sell and ProductsToInventory refers each product to the inventory items required for it.
Inventory lists the the name, size, and weight of the item
then InventoryDetails stores the cost, original quantity received, and the current quantity (since the company receives different quantities of the same product at different pricing all the time) (I would appreciate all the comments on this, this is
the best way I thought of doing this but if you have another way i'd appreciate it)
So that's the design, now we created a trigger that basically does this...
When an order is created and a PRODUCT is inserted into the the orderdetails, we will, using trigger, run the following query to insert the INVENTORY into the orderdetails
   INSERT INTO OrderDetails (...., OrderDetailPrice)
   SELECT ..., OrderDetailPrice?
FROM inserted i INNER JOIN ProductToInventories pt
    ON i.productid = pt.id
    INNER JOIN Inventories inv
    ON pt.InventoryID = inv.InventoryID
    LEFT JOIN InventoryDetails idet
    ON inv.InventoryID = idet.InventoryDetailInventoryID
    WHERE OrderDetailType = "PRODUCT"
This works perfectly fine, however... for the price, we don't know what to do here, since the price is not in the inventory, the price is under the inventorydetails and we will have to look up to that table to see which one has quantity > the quantity
needed here and then grab the price for that and then we need to update the quantity on that as well.

Here is the scenario, we have the following tables
Orders, OrderDetails, Products, ProductsToInventory, Inventory, and InventoryDetails
Orders is where .....
Good day TheSQLNewb,
I did not read more than I quote above... This is a starting of a nice story :-) but in the forum and in DBA's life we prefer to get DDL+DML instead of stories.
Please post queries to create the relevant tables (this is DDL by the way), and queries to insert some sample data (DML). with this information we will be able to reproduce the tables in our server and work on them.
Thanks :-)

Include or create a view in the database and use this view?

Well, I need to get related data of the main table from another related tables, so one way to do that is to use the Include method in Entity Framework to get this related data.
However, I am thinking in another option, create a view in the database and use this view in entity framework. In this way, I avoid the needed of the include, because I think that is expensive in resources. But I am no very sure about that.
I would like to know if the use of views on entity framework is a good idea to improve the performace or is better to use the include.
For example, if I use the include I have the advantage that I get only one the main record and all the related data I have in the navigation properties, so the info is more shorted.
Which is the advanteges and disadvantages of both methods to get related data in entity framework?
Thank so much.

Hello ComptonAlvaro,
>>I would like to know if the use of views on entity framework is a good idea to improve the performace or is better to use the include.
If your view would use a Join syntax to query master-child relationship tables, it actually is similar with the Include() method which actually results a duplicate records from master table, you could check this
link for detail description.
>>Which is the advanteges and disadvantages of both methods to get related data in entity framework?
One visible difference is that records from Views are not editable by default(if you want edit them, you could refer to this
blog).
In your case, my suggestion that you could use the lazying load which will load the matter table once and disable the trace if you only need to display data.

Hi, how do I create a standalone installer for Mountain Lion, ie, download once and then no more broadband required, thanks?

Hi, how do I create a standalone installer for Mountain Lion, ie, download once and then no more broadband required, thanks?
Context is that my other computers are not mobile and I do not have broadband worth troubling for a 4GB download - so will go to Apple Store with MacBook Pro for first download.

The easiest way is to download the installer but do not open it.
Next, make a copy of it and store it where it won't get lost.
Then take one of the copies and place into the applications directory and open it to begin the installer.
This has saved me the trouble of ever having to download the installer twice, plus you can mess around with the installer and try different options without having to worry about not having a clean install file if needed.
Best wishes

How do I create a product or item database so I can search fr the product and its files with hte pro

How do I create a product or item database so I can search for the product and its files with the products name or four digit code

Ok so I made some progress on this. I have figured out, that I can add a chained "add to cart" to certain items, then when they click the button for Buy now, it will add both items to the cart. However, this would require me to manually build each product page and generate a custom button for each one with both product IDs in it.
Can anyone offer help on how to put some JS in that would append a second function to the onclick function that BC Generates dynamically?
For the products that require a set up fee, I would assume I would add in to either the product templates or in to the item description some JS that would find the onclick of the buynow button and append a second function to also add to cart the setup fee product. The end result being code that looks like this:
<input type="submit" class="productSubmitInput" onclick="AddToCart(188536,6314368,'',4,'','',true);AddToCart(188536,6314367,'',4,'','',tr ue);return false;" value="Buy Now" name="AddToCart_Submit" />
Except of course, the product ID on the first AddToCart would be the main product with the second one being the one appended.
Does any of that make sense? lol

Create another sid and "database"?

Hello,
I've just installed a Oracle 8.0.5 into a linux box and
making some tests using the SID (ora) I gave to the installer
prompt. This means I can make a connection to this
database using sqlplus, e.g sqlplus user/passwd@ora.
I'm missing some terminology here, but I'd like to create
another database/tablespace/instance/whatever to be something
for testing, e.g. sqlplus user/passwd@tdev.
This far I've managed to alter the files listener.ora and
tnsnames.ora, so that the listener now says:
./lsnrctl status
Services Summary...
extproc has 1 service handler(s)
ora has 1 service handler(s)
tdev has 1 service handler(s)
But what is the next step here? When I try to create a
database that corresponds with the SID "tdev" I get:
./svrmgrl
connect internal
shutdown
startup nomount
create database tdev <lots of parameters>
ORA-01501: CREATE DATABASE failed
ORA-01504: database name 'TDEV' does not match parameter db_name
'ora'
Yours,
Marko
null

Many thanks for your advice, now it almost works.
I was able to create the database tdev and
after after adding users in it, I'm able to
connect it as well.
However, if I now try to connect any other database
(those ones on the same machine or those ones that
are depicted in tnsnames.ora), I always get the message:
ORA-01034: ORACLE not available
tnsping to those databases works fine and lsnrctl start
command gives me:
Services Summary...
extproc has 1 service handler(s)
ora has 1 service handler(s)
tdev has 1 service handler(s)
The command completed successfully
Yours,
marko

Create Temporary databases and Permanent databases

Hi,
How to configure or setup Temporary databases and Permanent databases ?
Need separate steps to install or setup Temporary / Permanent databases
Windows 2003 & 32 bit OS and 8 GB RAM
In web site http://docs.oracle.com/cd/E21901_01/doc/timesten.1122/e21633/comp.htm#CHDBEDHC
it is said as it is configured with DSN (Data Source Name)
but to how to setup Temporary databases and Permanent databases
Note:Oracle database has not been installed,only Oracle TimesTen has been installed.
Temporary databases are not stored to disk.
Permanent databases are stored to disk automatically through a procedure called checkpointing.
I need to keep the data in memory and need to pass the data to another server via replication or some other way.
Thanks!

Hi,
You dont need to install something. You need to configure your DSN only.
For creating Temporary database you should set up the Temporary DSN parameter (http://docs.oracle.com/cd/E21901_01/doc/timesten.1122/e21633/using.htm#BCGJAJDI).
If you want using Permanent database just uncheck Temporary DSN parameter.
Temporary databases are not stored to disk. Permanent databases are stored to disk automatically through a procedure called checkpointing. No. TimesTen databases (Permanent and Temporary) store data in memory. It is the main purpose. Permanent db saves a copy of data on disk only for recovery purpose. Temporary db doesnt do it.

Gennady

Difference between Instance Crash and Database Crash in Standalone and RAC?

Sivaprasad S wrote:

Literally, database crash means that the database itself is damaged in some way. A disk is no more. Data files are corrupted. Etc. The database itself thus causes the crash - and a database crash will also cause all database instances (RAC or single) for that database to crash too.
An instance crash will therefore mean that the crash occurs in the instance due to an Oracle bug or similar. In other words a s/w error and not a database error. The database is still "fine", but the instance not. Instance crashes. However, any other instance on that same (RAC) database will still be fine as the database itself is unaffected by that s/w error in the crashed instance.
If you mean something different, please enlighten us. Not all crashes are equal. {noformat};-){noformat}

How to create a .mdf SQL Server database from a Data-Tier Application file that has data?

This is a noob question, though I do use SQL Server databases all the time with Entity Framework when I code in C# using Visual Studio 2013. The development environment is found below at [A]. I am trying to make a clone of a SQL Server 2008 R2
database (.mdf) that exists online. I can read, connect and work with this database in Visual Studio 2013, but I wish to make a local copy of the database, as an .MDF file. Somewhere in my notes I have a way of creating a local copy from
an online database when using Visual Studio but I forgot how (it seems, reviewing my notes, that it deals with ADO.NET which is deprecated in Visual Studio 2013 these days, or so it seems). So I'm looking for another way. What I did was create
(or export) a "Data-Tier Application File" from the online SQL Server database, with data, and it seems to have worked in that this Data-Tier Application file exists on my hard drive and seems to have data in it ("SQL Server Replication Snapshot"
is the format it seems). It contains skeleton code to create a database, but when I tried to execute it with SQL Server 2014 Management Studio, I got a bunch of errors.
So my question is:
1) Can I somehow create a .MDF SQL Server Database from an Data-Tier Application file that has data? What tool do I use? I saw this link, http://social.technet.microsoft.com/wiki/contents/articles/2639.how-to-use-data-tier-application-import-and-export-with-a-windows-azure-sql-database.aspx
and it relates to Azure, but is there a tool for C#Visual Studio 2013, standalone?
2) If there's an easy way to create a .mdf SQL Server Database file from an online file, within SQL Server Management Studio? I don't think so, since it would require Administrator permissions on the online server, which I don't have. I have permission
to read, update, delete the online database file, but strangely not to download it (the service I use has a tool for backup, but not for download).
3) same question as 2), but for Visual Studio 2013? I don't think so, since I notice none of the templates even mentions ADO.NET anymore, but instead they go with Entity Framework. Using EF I can of course do anything I want with the online database
(CRUD), but it remains online. Maybe there's a switch to make a local copy? I guess I could write a short program to suck all the data out of the online database and put it into a new, duplicate database having the same tables, that I create on
my localhost, but my question here is if there's an easier way than this, maybe a tool or command I can run from inside Visual Studio?
Any advice on any of the above questions is appreciated.
Thank you,
