What do you suggest me me to task "Please comment up all tables in the database.

I in Oracle database 10g in a diagram ca 600 ('business') tables created. Most of these tables have no comments.
I do not understand most of the tables, and nobody does. Can you give me some advice, how should I start to comment on these tables?
I just want to put comments first to tables, later, I shall refer columns.
I understand that some tables are with mandatory data to the system, something like table ala "What" would sound to be with mandatory 3 rows that are needed for the system to run. some tables contains mandatory data for the system, such as ala 'UserOptions"which sounds like it contains data that the user has inserted itself, if these data are not important for the system. Maybe I could distinguish between tables in other, perhaps some other tips are important to clarify the purpose of the table.
Can you suggest something useful how do I do the commentary to these 600 tables?
If you're dazzled that there are not many people who might know the porpouse of the tables, then you should not be surprised, take this as a reality.
I dig in the Java code that uses these tables, I think what's ' will be a lot of comments either.

If I were you CharlesRoos, I would be first to reverse engineer the schema/database. It is easier to understand the link between the business tables when you see actually graphically ;-)

Also, you may find that some tables are on security (users, roles, profiles, granted by screen, etc), others may be connected to a workflow "internal" demand, etc etc.

It's easier to do when you have the graphics. I'm saying; I just hope that you do not try to understand your database using SQLPlus :))

See you soon,.

  • I used to have "app tabs" and it has now disappeared. I recently upgraded to Firefox & I also changed the skin. What can you suggest for me?

    How can I get that back?

    You could try story ('Alt + S') > "Restore preivous session", then also of the story then 'restore Windows' > 'restore all windows.

    You get back them or re-create them, I would suggest that you save all in a folder of bookmarks for your restore them immediately and pin them each, or altogether if you have the extension «Multiple Tab Handler»

    Although I don't have a problem with them disappear when I run Firefox, they have always seemed like a potential problem over time. I use them, but I often start their from a folder Favorites so are 'clean' only one page by app - tab.

  • What would you suggest that I update on my computer?

    I got a hold of a pretty nice computer, but I don't know what to do to make a platform game "evolutionary" (at the lowest possible cost).

    You can opt for another AMD card. Something like a 270 R9 or 270 x would give a helping hand

    for game performance. These cards are low/medium of mid-range, respectively.

    Power supply - depends on which of the two versions provided with this unit.

    The model 85 + money would be desirable, as a 525W PSU is close to the minimum capacity for a

    R9 270/270 X that has a minimum of 500W (suggested minimum of Gigabyte).

    -A good quality all about 600W power would be necessary with a 280 R9 or 280 X.

    You should read a few comments (material, not NewEgg or Amazon sites) to compare the performance between the above four maps, or the 260 series if you want something less expensive.

  • When you import photos into LR4, import feature does not all photos in the folder

    I have a catalog with all the imported pictures from a trip I just got back from.  But when I compare the catalog for real photos in the folder, there are 104 missing photos from the catalogue.  If I try to sync the catalog, it says 104 photos must be imported, but the import process said that there are no new photos.

    I created a new catalog and tried to import the file again, but its lack still the same images of 104.

    I don't know what to do here.  Help, please.

    There are only three reasons that I see which files are not imported:

    1. the issue of Raw + Jpeg, you already have reduced.

    2 not supported file types. So is there anything on these 104 images that are unusual in a perspective of file type? What kind of file, what device, what version of LR4 (4.0 or 4.1).

    3. already imported file. Seems more likely that you said that you "they remind of where everything what he. Have you tried to identify one of the 104 files and then find in Lightroom (use the text search option in the library filter bar).

    Hello

    There are a number of possible reasons, your computer may run slowly - virus infection or malware, missing to defragment the hard drive, too many programs loading at startup - and all with different causes / solutions. So here goes:

    Virus/Malware - Download, install and run these scanners (only Avast so you do not have your own antivirus installed):

    Malwarebytes': http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html .

    SuperAntiSpyware: http://download.cnet.com/SuperAntiSpyware-Free-Edition/3000-8022_4-10523889.html .

    Avast Antivirus: http://download.cnet.com/Avast-Free-Antivirus/3000-2239_4-10019223.html .

    Disk Defragging - install and run this app: http://download.cnet.com/Auslogics-Disk-Defrag/3000-2094_4-10567503.html .

    Startup programs - install this application, then select start only the programs you need to run at startup, as your antivirus, firewall, but not your Disk Defragmenter (examples):

    Splash Guard: http://download.cnet.com/Startup-Guard/3000-2239_4-10958203.html.

    Also, your system's drivers are up-to-date? Updated the driver can also slow down your system. Go to HP.com and insert the complete your laptop model number in the search box to find your latest drivers.

    Let me know if these speed up your pc.

  • End of the year catching up... what will you do?

    As we approach the end of the year, many of us (especially those in B2B) will see the last two weeks and the first week (maybe) to slow down a little. With ALL that extra time on your hands (not) what you pick up that you have not had time to do earlier in the year? Metrics? Data cleansing? Deduping files? Drive speed test?

    For me this year it will be all about the lead flow. We have many different processes and groups, and this year I will take the time to look at where everything is happening, how long it takes to get where it needs to go, and where the gaps are.

    What will you do

    We will be transitioning our lead scoring model to the new interface of E10, which will involve a lot of tests and re-evaluation.  We must determine a way to translate the A1, B1, C1, etc. in gross to mesh with some marking campaign that we have in Salesforce.

    I also need to archive some contacts bounced and unsubscribed off Eloqua... because of some new lead gen efforts, we hit our limit of contact. Yay!

  • Remote Desktop connection - how do you find the databases

    Objective: see Web site and code that someone has written/produced in ASPX.NET and MS SQL Server 2008 database.

    The reason is that, the website and the database need some changes (to be able to do that, I also know the names of tables-> SQL-> database query).

    I didn't have the right to communicate with someone who made this Web site (this task is different)

    Using Remote Desktop connection, I connected to the server where our Web site is hosted.

    It shows me this:

    http://S13.postimg.org/5xkwpn7lj/Pic_1.jpg

    http://S3.postimg.org/niz6si5cz/Pic_2.jpg

    Question: How do you get to the tables in the databases?

    I'm still a beginner on this remote connection.

    Do you need to download another SQL Server (Microsoft SQL Server 2014 Express) software on my laptop and ASPX.NET to add remote connection via the connection code?

    Can I change/add code directly to its SQL Server software?

    I also see its databases?
